一种煤矿井下突水预警监测装置及方法An early warning and monitoring device and method for water inrush in a coal mine

技术领域technical field

本发明涉及煤矿突水预警技术领域，尤其涉及一种煤矿井下突水预警监测装置及方法。The invention relates to the technical field of coal mine water inrush early warning, in particular to a coal mine underground water inrush early warning monitoring device and method.

背景技术Background technique

矿井突水是掘进或采矿过程中当巷道揭穿导水断裂、富水溶洞、积水老窿，大量地下水突然涌入矿山井巷的现象。当巷道底板下有间接充水层时，便会在地下水压力和矿山压力作用下，破坏底板隔水层，形成人工裂隙通道，导致下部高压地下水涌入井巷造成突水。矿井突水一般来势凶猛，常会在短时间内淹没坑道，给矿山生产带来危害，造成人员伤亡。在富水的岩溶水充水的矿区及顶底板有较厚高压含水层分布的矿山区，在构造破碎的地段，常易发生矿井突水。Mine water inrush is a phenomenon in which a large amount of groundwater suddenly pours into the mine shaft when the roadway exposes the water-conducting fracture, the water-rich karst cave, and the water-filled hole during the excavation or mining process. When there is an indirect water-filled layer under the roadway floor, under the action of groundwater pressure and mine pressure, the floor aquifer will be destroyed, forming artificial crack channels, resulting in the influx of high-pressure groundwater from the lower part of the well and roadway. Mine water inrush is generally ferocious, often flooding tunnels in a short period of time, causing harm to mine production and causing casualties. In the mining area filled with water-rich karst water and the mining area with thick high-pressure aquifers distributed on the roof and floor, mine water inrush is often prone to occur in the section with broken structure.

水灾对矿井造成的破坏是毁灭性的，由于水灾发生的预测性难的原因，一旦水灾发生，不仅会造成矿井人员的严重伤亡，造成难以估算的损失，同时还会对矿井造成难以修复的结局，造成的经济损失更是不言而喻。更有一个明显的问题就是水灾造成的矿井灾害抢救难度大，一旦产生水灾，基本上很难在有限的时间内挽回人员的生命和经济损失。所以说水害是影响矿井安全的非常重要的问题之一。The damage caused by floods to mines is devastating. Due to the difficulty in predicting the occurrence of floods, once a flood occurs, it will not only cause serious casualties of mine personnel and cause incalculable losses, but also cause difficult repairs to the mine. , the economic loss is self-evident. Another obvious problem is that it is very difficult to rescue mine disasters caused by floods. Once floods occur, it is basically difficult to save lives and economic losses within a limited time. Therefore, water damage is one of the very important issues affecting mine safety.

现有煤矿突水监测方法往往采用水质、水量、温度、湿度、气体成分、裂隙等单一监测指标对矿井突水进行监测，监测结果准确性差。对于现有通过监测水质来进行煤矿井下突水预警监测的监测装置，因为水流中掺杂有碎石等杂物，容易撞击到水质传感器，造成水质传感器的损坏，不利于进行长期稳定的水质监测，对于简单设置滤网进行遮挡的方式，滤网容易堵塞，使监测装置丧失监测功能。现有煤矿突水监测方法只能监测是否发生突水或者在突水前进行预判，却忽视了对于已经发生突水的矿井的水仓内的水位监测，因此无法对水仓内的设备进行及时安全有效地抢救。The existing coal mine water inrush monitoring methods often use single monitoring indicators such as water quality, water quantity, temperature, humidity, gas composition, and fissures to monitor mine water inrush, and the monitoring results are inaccurate. For the existing monitoring devices that monitor water quality in coal mines for early warning and monitoring of underground water inrush, because the water flow is mixed with debris such as gravel, it is easy to hit the water quality sensor, causing damage to the water quality sensor, which is not conducive to long-term and stable water quality monitoring. , For the way of simply setting the filter screen to block, the filter screen is easy to block, so that the monitoring device loses the monitoring function. The existing coal mine water inrush monitoring methods can only monitor whether water inrush occurs or make predictions before water inrush, but ignore the water level monitoring in the water tank of mines where water inrush has occurred, so it is impossible to monitor the equipment in the water tank. Timely, safe and effective rescue.

与现有技术相比，本发明的上述技术方案具有如下有益的技术效果：Compared with the prior art, the above-mentioned technical solutions of the present invention have the following beneficial technical effects:

1、本发明能在保证水质传感器正常监测的前提下，对水质传感器进行安全防护，且能避免导流罩、第一滤板和第二滤板的堵塞情况发生，有利于长时间稳定的进行水质监测，从而能长时间进行煤矿井下突水预警监测。1. The present invention can protect the water quality sensor safely under the premise of ensuring the normal monitoring of the water quality sensor, and can avoid the blockage of the shroud, the first filter plate and the second filter plate, which is conducive to long-term stable performance. Water quality monitoring, so as to carry out early warning monitoring of underground water inrush in coal mines for a long time.

2、驱动机构驱动导流罩和转动柱转动，转动柱带动第一螺旋叶片转动。当水流流动至导流罩处时，水流沿着导流罩外周面流动，因为康达尔效应，水流易于在半球形罩状结构的导流罩外表面上流动，易于流至导流槽内，沿着弧线形的导流槽流动，并在流动过程中通过进水孔穿过导流罩，碎石会在撞击到转动状态下的导流罩时向外侧流动，不易进入导流槽和进水孔内，不易堵塞进水孔，即便进入导流槽，也会从导流槽的终点端流动出去，第一滤板在保证水流顺畅流动的前提下起到进一步的防护作用。2. The drive mechanism drives the shroud and the rotating column to rotate, and the rotating column drives the first spiral blade to rotate. When the water flow flows to the shroud, the water flow flows along the outer peripheral surface of the shroud. Because of the Condall effect, the water flow is easy to flow on the outer surface of the shroud of the hemispherical cover structure, and it is easy to flow into the guide groove. It flows along the arc-shaped diversion groove and passes through the diversion hood through the water inlet hole during the flow process. The gravel will flow to the outside when it hits the diversion hood in the rotating state, and it is not easy to enter the diversion groove and the diversion hood. In the water inlet hole, it is not easy to block the water inlet hole. Even if it enters the diversion groove, it will flow out from the end of the diversion groove. The first filter plate plays a further protective role under the premise of ensuring the smooth flow of water.

3、水流进入安装筒内后，由第二螺旋叶片对水流进行导流，使水流中的不同成分能够分布均匀，由水质传感器对水质进行监测，节省监测所需时间，提高监测效率，并在监测到水中掺杂有从涌入的地下水时，向中央控制器发送信号，启动声光报警器进行报警，有效提高了预警效率，有利于工作人员及时撤离，有利于保障人员安全。3. After the water flow enters the installation cylinder, the water flow is diverted by the second helical blade, so that the different components in the water flow can be evenly distributed, and the water quality is monitored by the water quality sensor, which saves the time required for monitoring and improves the monitoring efficiency. When it is detected that the water is mixed with the influx of groundwater, a signal is sent to the central controller, and the sound and light alarm is activated to give an alarm, which effectively improves the early warning efficiency, helps the staff to evacuate in time, and helps to ensure the safety of the personnel.

4、本发明的矿井突水灾害监测系统，利用煤矿井下突水预警监测装置的水质监测机构实施监测矿井水水质变化、震动监测机构实时监测煤矿巷道的振动信号，利用水仓水位监测装置实时监测水仓内的水位，通过水仓内的水位变化情况判断是否发生突水，利用矿井突水灾害预警的组合传感器监测装置对巷道钻孔内的温度、裂隙、裂隙渗水以及渗水水质情况进行实时监测，通过对矿井内的排水沟、水仓以及巷道底壁、侧壁等多个位置进行同时监测，且基于矿井水的水质、水位、巷道壁的震动、裂隙及裂隙内渗水情况等多参数对矿井突水灾害进行综合判断，使得监测结果更准确、更可靠，当发生矿井突水时监测系统能够及时提醒工作人员，而且有助于根据报警位置判断突水水源来向，预警效果好。4. The mine water inrush disaster monitoring system of the present invention uses the water quality monitoring mechanism of the coal mine underground water inrush early warning monitoring device to monitor the change of mine water quality, the vibration monitoring mechanism monitors the vibration signal of the coal mine roadway in real time, and uses the water tank water level monitoring device to monitor the real-time monitoring. The water level in the water silo is judged by the change of the water level in the water silo to determine whether water inrush occurs, and the combined sensor monitoring device for mine water inrush disaster warning is used to monitor the temperature, fissures, fissure water seepage and seepage water quality in the tunnel borehole in real time. , through simultaneous monitoring of multiple locations such as drainage ditches, water tanks, and the bottom and side walls of the roadway in the mine, and based on multiple parameters such as mine water quality, water level, roadway wall vibration, fissures and water seepage in the fissures, etc. Comprehensive judgment of mine water inrush disasters makes monitoring results more accurate and reliable.

考虑到传统水质传感器15均为刚性安装，一旦完成安装在测试过程中是无法进行移动的，一旦有颗粒物撞击容易损坏水质传感器15。本实施例中，进入安装筒3内的矿井水流中不可避免夹带一定粒径的颗粒物杂质，由于安装筒3内的矿井水的流水较高，较高速度的颗粒物杂质撞击水质传感器15，容易导致水质传感器15损坏。因此，基于上述问题，本实施例中第二安装台30的一个优选实施方式，水质传感器15采用柔性安装的方式，第二安装台30的第二中心孔的孔径大于水质传感器15的外径尺寸，第二中心孔内安装减震件，也即水质传感器15通过减震件安装于第二中心孔内，减震件能够降低矿井水中颗粒物杂质对水质传感器15的撞击损害，提升水质传感器15的使用寿命，保证监测结果的连续性与可靠性。Considering that the traditionalwater quality sensor 15 is rigidly installed, once the installation is completed, it cannot be moved during the test process, and thewater quality sensor 15 may be easily damaged once a particle strikes. In the present embodiment, particulate impurities of a certain size are inevitably entrained in the mine water flow entering theinstallation cylinder 3. Since the flow of the mine water in theinstallation cylinder 3 is relatively high, the high-speed particulate impurities impinge on thewater quality sensor 15, which is easy to cause Thewater quality sensor 15 is damaged. Therefore, based on the above problems, in a preferred implementation of thesecond installation platform 30 in this embodiment, thewater quality sensor 15 adopts a flexible installation method, and the diameter of the second central hole of thesecond installation platform 30 is larger than the outer diameter of thewater quality sensor 15 , a shock absorbing member is installed in the second central hole, that is, thewater quality sensor 15 is installed in the second central hole through the shock absorbing member. The shock absorbing member can reduce the impact damage to thewater quality sensor 15 caused by the particles in the mine water The service life ensures the continuity and reliability of the monitoring results.

具体而言，减震件的一种结构为弹性充填物，如弹性橡胶，第二中心孔的孔径大于水质传感器15的外径，在水质传感器15与第二中心孔的环形空间内充填弹性橡胶，通过充填弹性橡胶不仅能够起到减震的作用，而且能够起到密封的作用。Specifically, a structure of the shock absorbing member is an elastic filler, such as elastic rubber, the diameter of the second central hole is larger than the outer diameter of thewater quality sensor 15, and the annular space between thewater quality sensor 15 and the second central hole is filled with elastic rubber , By filling elastic rubber, it can not only play the role of shock absorption, but also play the role of sealing.

具体而言，减震件的另一种结构为弹簧，水质传感器15与第二中心孔的环形空间内安装多个弹簧，水质传感器15利用多个弹簧，优选4个弹簧固定在第二中心孔内，弹簧的第一端固定在第二中心孔的孔壁，弹簧的第二端抵靠在水质传感器15的外周壁，或者，水质传感器15的下部套设连接环，弹簧的第二端与连接环连接。自然状态下，弹簧均为拉伸状态，水质传感器15位于第二中心孔的中心线上，当矿井水中的颗粒撞击水质传感器15时，水质传感器15会向下游方向摆动，挤压下游方向的弹簧，并在上游弹簧拉力作用下使水质传感器15复位，此过程实现减震效果。Specifically, another structure of the shock absorber is a spring, and a plurality of springs are installed in the annular space between thewater quality sensor 15 and the second central hole, and thewater quality sensor 15 uses a plurality of springs, preferably four springs, are fixed in the second central hole Inside, the first end of the spring is fixed on the hole wall of the second central hole, the second end of the spring abuts on the outer peripheral wall of thewater quality sensor 15, or the lower part of thewater quality sensor 15 is sleeved with a connecting ring, and the second end of the spring is connected to the outer peripheral wall of thewater quality sensor 15. Connection ring connection. In the natural state, the springs are all stretched, and thewater quality sensor 15 is located on the center line of the second center hole. When the particles in the mine water hit thewater quality sensor 15, thewater quality sensor 15 will swing in the downstream direction, squeezing the spring in the downstream direction. , and under the action of the upstream spring tension, thewater quality sensor 15 is reset, and this process achieves the shock absorption effect.

为了进一步降低矿井水流中夹带的颗粒物撞击水质传感器导致损坏的可能性，第二安装台30的第二中心孔的上部孔径小于下部孔径，由上向下，第二中心孔的孔径逐渐变大，第二中心孔的纵向截面呈喇叭状或八字形，第二中心孔的下部空间构成摆动空间，水质传感器15装入第二中心孔后，水质传感器15的上部与第二中心孔的上部通过球铰转动连接，水质传感器15的下部能够在矿井水的冲击下在摆动空间内摆动。In order to further reduce the possibility of damage to the water quality sensor caused by the impact of particulate matter in the mine water flow, the upper aperture of the second central hole of thesecond installation platform 30 is smaller than the lower aperture, and the aperture of the second central hole gradually increases from top to bottom. The longitudinal section of the second central hole is in a trumpet shape or a figure-eight shape, and the lower space of the second central hole constitutes a swing space. After thewater quality sensor 15 is installed in the second central hole, the upper part of thewater quality sensor 15 and the upper part of the second central hole pass through the ball. The hinge is connected, and the lower part of thewater quality sensor 15 can swing in the swing space under the impact of mine water.

在一个可选的实施例中，呈喇叭状或八字形结构的第二中心孔内设置减震件，也即第二中心孔的摆动空间内充填弹性充填物，或者，摆动空间内设置弹簧，第二中心孔的下部的摆动空间允许水质传感器15的下部在小范围内摆动，减震件能够进一步减少撞击损坏，而且能够使水质传感器15及时复位。第二安装台30的第二中心孔设置供水质传感器15的摆动空间，同时摆动空间内设置减震件，将水质传感器15柔性安装，双重防损坏结构能够有效防止因矿井水流中夹带的颗粒物撞击水质传感器导致损坏，提升了监测装置的工作稳定性。In an optional embodiment, a shock absorbing member is arranged in the second central hole having a trumpet-shaped or figure-eight structure, that is, the swing space of the second central hole is filled with an elastic filler, or a spring is arranged in the swing space, The swing space in the lower part of the second central hole allows the lower part of thewater quality sensor 15 to swing in a small range, the shock absorber can further reduce the impact damage, and can make thewater quality sensor 15 reset in time. The second center hole of thesecond installation platform 30 is provided with a swing space for thewater quality sensor 15. At the same time, a shock absorber is arranged in the swing space to flexibly install thewater quality sensor 15.

In the natural state, thebaffle 32 sags under the action of gravity. At this time, the periphery of the water-facing surface of thebaffle 32 is in sealing contact with the entire limiting part, which separates the water outlet end of theinstallation cylinder 3 from thesecond filter plate 4, so as to avoid downstream backflow The mine water enters theinstallation cylinder 3 in reverse through the water outlet of theinstallation cylinder 3 . When the upstream mine flowing water enters theinstallation cylinder 3, it flows through thefirst filter plate 2 and thesecond filter plate 4 in sequence, and the flowing water passing through thesecond filter plate 4 hits thepartition plate 32, thepartition plate 32 is opened, and the flowing water in the mine is installed by the installation The water outlet of thecylinder 3 is normally discharged; when the upstream flow rate is small, thepartition 32 is reset by its own gravity to separate the water outlet of theinstallation cylinder 3 from thesecond filter plate 4, and at the same time, theinstallation cylinder 3 can always maintain a certain amount of water storage. , so that thewater quality sensor 15 can monitor the water quality data, which is helpful to improve the monitoring effect; when the mine water is backlogged downstream, the backwashed mine water impacts the back surface of thepartition 32, which can quickly reset thepartition 32 to the upstream direction. The water outlet end of theinstallation cylinder 3 is separated from thesecond filter plate 4 to prevent impurities entrained in the backflow water from clogging thesecond filter plate 4 and to ensure the working stability of the monitoring device.

Specifically, thevibration sensor 21 is adjusted to a position in contact with the inner wall of the coal mine roadway, and thevibration sensor 21 is used to monitor the vibration of the roadway. When the inner wall of the roadway is monitored to vibrate, it indicates that there is a possibility of underground water inrush in the coal mine. Thecontroller 16 sends a signal, thecentral controller 16 controls the sound andlight alarm 17 to give an alarm, and uses thevibration sensor 21 and thewater quality sensor 15 to monitor at the same time, and the monitoring range is wider.

与现有技术相比，本实施例的煤矿井下突水预警监测装置及方法具有如下有益技术效果：Compared with the prior art, the coal mine underground water inrush early warning monitoring device and method of the present embodiment has the following beneficial technical effects:

1、本发明能在保证水质传感器正常监测的前提下，对水质传感器进行安全防护，且能避免导流罩、第一滤板和第二滤板的堵塞情况发生，有利于长时间稳定的进行水质监测，从而能长时间进行煤矿井下突水预警监测。1. The present invention can protect the water quality sensor safely under the premise of ensuring the normal monitoring of the water quality sensor, and can avoid the blockage of the shroud, the first filter plate and the second filter plate, which is conducive to long-term stable performance. Water quality monitoring, so as to carry out early warning monitoring of underground water inrush in coal mines for a long time.

2、利用固定架将本装置固定在排水沟旁边，导流罩、第一滤板、安装筒和第二滤板均被放置在煤矿巷道排水沟内，且不会与排水沟内壁接触。2. Use the fixing frame to fix the device beside the drainage ditch. The diversion cover, the first filter plate, the installation cylinder and the second filter plate are all placed in the drainage ditch of the coal mine roadway, and will not contact the inner wall of the drainage ditch.

3、驱动机构驱动导流罩和转动柱转动，转动柱带动第一螺旋叶片转动。当水流流动至导流罩处时，水流沿着导流罩外周面流动，因为康达尔效应，水流易于在半球形罩状结构的导流罩外表面上流动，易于流至导流槽内，沿着弧线形的导流槽流动，并在流动过程中通过进水孔穿过导流罩，碎石会在撞击到转动状态下的导流罩时向外侧流动，不易进入导流槽和进水孔内，不易堵塞进水孔，即便进入导流槽，也会从导流槽的终点端流动出去，第一滤板在保证水流顺畅流动的前提下起到进一步的防护作用。3. The drive mechanism drives the shroud and the rotating column to rotate, and the rotating column drives the first spiral blade to rotate. When the water flow flows to the shroud, the water flow flows along the outer peripheral surface of the shroud. Because of the Condall effect, the water flow is easy to flow on the outer surface of the shroud of the hemispherical cover structure, and it is easy to flow into the guide groove. It flows along the arc-shaped diversion groove and passes through the diversion hood through the water inlet hole during the flow process. The gravel will flow to the outside when it hits the diversion hood in the rotating state, and it is not easy to enter the diversion groove and the diversion hood. In the water inlet hole, it is not easy to block the water inlet hole. Even if it enters the diversion groove, it will flow out from the end of the diversion groove. The first filter plate plays a further protective role under the premise of ensuring the smooth flow of water.

4、水流进入安装筒内后，由第二螺旋叶片对水流进行导流，使水流中的不同成分能够分布均匀，由水质传感器对水质进行监测，节省监测所需时间，提高监测效率，并在监测到水中掺杂有从涌入的地下水时，向中央控制器发送信号，启动声光报警器进行报警，有效提高了预警效率，有利于工作人员及时撤离，有利于保障人员安全。4. After the water flow enters the installation cylinder, the water flow is diverted by the second helical blade, so that the different components in the water flow can be evenly distributed, and the water quality is monitored by the water quality sensor, which saves the time required for monitoring and improves the monitoring efficiency. When it is detected that the water is mixed with the influx of groundwater, a signal is sent to the central controller, and the sound and light alarm is activated to give an alarm, which effectively improves the early warning efficiency, helps the staff to evacuate in time, and helps to ensure the safety of the personnel.

实施例2Example 2

矿井突水前会有多种预兆，比如工作面顶板掉渣、冒顶、支架倾倒或折梁断柱、底软膨胀、底膨张裂、采掘面围岩内出现裂缝等现象，然而发生这种明显前兆时，往往在很短时间内就会发生突水或者垮塌灾害，工作人员短时间内无法迅速逃离工作面达到安全地带。在上述前兆的发生初期，巷道内壁以及采煤工作面上煤岩体的裂隙就已发生明显变化，如裂隙数量增多(也即单位面积内裂隙密度增大)、裂隙宽度变大、裂隙长度变长，而且多数情况裂隙内还会有水渗出，然而上述这些特征的变化程度相对较小，往往肉眼无法直接判断，现有监测装置往往只监测顶板、底板、巷道侧壁表面的裂隙发育，并未对岩体内的裂隙进行监测，而透水前的煤岩裂隙是由内向外发育的，能够及时监测到煤岩体内部裂隙发育变化情况，对矿井突水的预判具有重要意义。Before the mine water inrush, there will be various signs, such as slag falling from the roof of the working face, roof fall, support dumping or broken beams and columns, bottom soft expansion, bottom expansion cracks, cracks in the surrounding rock of the mining face, etc. However, this phenomenon occurs. When there are obvious precursors, water inrush or collapse disasters often occur in a very short period of time, and workers cannot quickly escape from the working face to reach a safe area in a short period of time. In the early stage of the occurrence of the above-mentioned precursors, the fissures of the inner wall of the roadway and the coal-rock mass on the coal mining face have changed significantly, such as the increase in the number of fissures (that is, the increase in the density of fissures per unit area), the increase in the width of the fissures, and the change in the length of the fissures. In most cases, there will be water seepage in the cracks. However, the degree of change of these characteristics is relatively small, and it is often impossible to directly judge with the naked eye. The fissures in the rock mass were not monitored, but the coal rock fissures before water permeation developed from the inside to the outside, and the development and changes of the internal fissures in the coal rock mass can be monitored in time, which is of great significance for the prediction of mine water inrush.

基于上述分析，本发明的又一具体实施例，公开了一种矿井突水灾害预警的组合传感器监测装置，如图7至图10所示，包括机架34、伸缩机构、旋转机构和探杆45，伸缩机构、旋转机构固定设于机架34上，伸缩机构与旋转机构连接，旋转机构与探杆45连接，伸缩机构用于驱动旋转机构沿伸缩方向移动，旋转机构用于驱动探杆45旋转并固定在指定旋转角度位置；探杆45的外周上安装有组合传感器。Based on the above analysis, another specific embodiment of the present invention discloses a combined sensor monitoring device for early warning of mine water inrush disaster, as shown in Figs. 45.

Use the humidity sensor to detect the humidity parameters in the hole, and predict the mine water inrush according to the changes of the parameters in the results of multiple humidity monitoring; use the water level sensor to detect whether there is water in the hole.

According to the information of humidity parameters, crack parameters and water level parameters in the detection hole, comprehensively judge whether water seepage occurs in the detection hole. Water accumulates, and the water level tends to rise. From this, it can be judged that water seepage has occurred in the cracks in the detection hole, and there is a possibility of water inrush.

在一个可选的实施例中，组合传感器还包括温度传感器、水质传感器，温度传感器用于检测检测孔内的温度，如果检测孔内发生渗水，水质传感器检测渗水的水质，通过温度参数、水质参数对矿井突水结果预判提供辅助参考。In an optional embodiment, the combined sensor further includes a temperature sensor and a water quality sensor. The temperature sensor is used to detect the temperature in the detection hole. If water seepage occurs in the detection hole, the water quality sensor detects the water quality of the seepage water. It provides an auxiliary reference for the prediction of mine water inrush results.

需要说明的是，本实施例中根据各监测参数作出突水预警监测结果，可以由经验丰富的技术人员判断，也可以由计算机处理系统自动判断。优选采用计算机处理系统自动判断，计算机处理系统基于监测到的温度、湿度、裂隙及水位、水质等参数，与预设的各参数阈值范围比对，利用模糊综合评判法、人工神经网络、灰色关联分析等方法，对矿井突水进行预判，并将预判结果显示在远端监控屏幕上，一旦发生突水预判，则发出警报。It should be noted that, in this embodiment, the water inrush early warning monitoring results are made according to various monitoring parameters, which can be judged by experienced technicians, or can be judged automatically by a computer processing system.

以图7-图10所示的矿井突水灾害预警的组合传感器监测装置对底板上检测孔检测为例，矿井突水灾害预警监测方法，包含以下步骤：Taking the detection of the detection holes on the bottom plate by the combined sensor monitoring device for early warning of mine water inrush disaster shown in Figures 7-10 as an example, the mine water inrush disaster early warning and monitoring method includes the following steps:

a)采用钻机根据需要检测需求钻取多组检测孔，每组检测孔包括多个检测孔，每组的检测孔均匀分布在同一圆周上，优选每组检测孔的数量为4-6个，检测孔的深度在0.5-2m之间，并将矿井突水灾害预警的组合传感器监测装置固定在每组检测孔所在圆周的中心位置。在矿井不同位置布设多组检测孔，利用多个监测装置以实现矿井内多位置同步监测。a) Use a drilling rig to drill multiple groups of inspection holes according to the inspection requirements. Each group of inspection holes includes multiple inspection holes, and the inspection holes of each group are evenly distributed on the same circumference. Preferably, the number of inspection holes in each group is 4-6. The depth of the detection holes is between 0.5-2m, and the combined sensor monitoring device for mine water inrush disaster warning is fixed at the center of the circle where each group of detection holes is located. Multiple sets of detection holes are arranged at different positions in the mine, and multiple monitoring devices are used to realize simultaneous monitoring of multiple positions in the mine.

b)调整可调支腿33使得机架34顶面保持水平，使旋转筒37的中心线通过检测孔所在圆周的圆心，伺服驱动器38转动带动旋转筒37上的连接筒35转动，从而带动转臂44转动到当前检测孔处。b) Adjust theadjustable legs 33 to keep the top surface of theframe 34 horizontal, so that the center line of therotating cylinder 37 passes through the center of the circle where the detection hole is located, and theservo driver 38 rotates to drive the connectingcylinder 35 on therotating cylinder 37 to rotate, thereby driving therotating cylinder 35. Thearm 44 is rotated to the current detection hole.

c)伸缩电缸41向下运动，驱动升降板42沿着导柱49向下运动，进而带动基板43上的中心轴46向下运动，从而使得滚珠导向轴50上的转臂44向下运动，将探杆45由当前检测孔的孔口插入到检测孔的孔底，插入过程中探杆45上的摄像机、传感器获取检测孔内裂隙、湿度、水位等参数信息。c) The telescopicelectric cylinder 41 moves downward, and drives the liftingplate 42 to move downward along theguide column 49, thereby driving thecentral shaft 46 on thebase plate 43 to move downward, so that therotating arm 44 on the ball guideshaft 50 moves downward , Insert theprobe rod 45 from the current hole of the detection hole to the bottom of the detection hole. During the insertion, the camera and sensor on theprobe rod 45 obtain parameter information such as cracks, humidity and water level in the detection hole.

d)测量完成后，伸缩电缸41带动探杆45上升到初始位置处，然后，伺服驱动器38带动转臂44上的探杆转动至下一个检测孔处，对下一检测孔进行检测。d) After the measurement is completed, the telescopicelectric cylinder 41 drives theprobe rod 45 to rise to the initial position, and then theservo driver 38 drives the probe rod on therotating arm 44 to rotate to the next detection hole to detect the next detection hole.

e)重复步骤c)和d)检测完所有的检测点。经过一定时间间隔后，对所有检测点重新进行再次监测，按照预设的时间间隔(如每隔2小时)对检测点进行重复监测，保证监测的持续性。e) Repeat steps c) and d) to detect all the detection points. After a certain time interval, all detection points are re-monitored, and the detection points are repeatedly monitored according to a preset time interval (eg, every 2 hours) to ensure the continuity of monitoring.

在步骤c中，在探杆45伸入检测孔过程中，摄影机对检测孔的孔壁进行拍摄，得到检测孔孔壁的三维虚拟柱状图和钻孔孔壁展开图，计算机处理单元对摄影机获取的图像进行处理，获得裂隙图像并识别出裂隙参数，裂隙参数包括裂隙数量、裂隙密度以及裂隙长度参数，并记录该检测孔的编号以及检测批次，计算机处理单元处理后的裂隙图像、检测孔内裂隙参数传输至远程控制端，并显示在远程控制端的屏幕上；湿度传感器检测孔内的湿度参数、水位传感器检测孔内是否有积水和水位变化信息，检测孔内的湿度、水位参数信息传输至远程控制端，并显示在远程控制端的屏幕上。In step c, when theprobe rod 45 extends into the detection hole, the camera shoots the hole wall of the detection hole to obtain a three-dimensional virtual histogram of the detection hole hole wall and an expanded view of the drilling hole wall, and the computer processing unit obtains the camera The image of the crack is processed to obtain the crack image and identify the crack parameters, including the number of cracks, crack density and crack length parameters, and record the number of the inspection hole and the inspection batch, the crack image and inspection hole processed by the computer processing unit The internal fissure parameters are transmitted to the remote control terminal and displayed on the screen of the remote control terminal; the humidity sensor detects the humidity parameters in the hole, the water level sensor detects whether there is accumulated water in the hole and the water level change information, and detects the humidity and water level parameter information in the hole transmitted to the remote console and displayed on the remote console's screen.

利用摄影机对布置在矿井内的所有检测孔进行探测，通过间隔多次检测孔内裂隙的发育变化情况，若同一检测孔多次监测结果显示：裂隙变宽、变长、密度变大，且变化程度达到一定时，也即预先设置裂隙参数变化阈值，当裂隙参数变化达到阈值范围时，则可能发生突水；若不同位置检测孔的监测结果具有规律性变化，且整体上裂隙监测结果显示：裂隙变宽、变长、密度变大，且至少有部分检测孔的裂隙变化程度达到预先设置的裂隙参数变化阈值范围，则可以预判可能发生突水的位置，对可能发生的位置进行处理，如注浆锚索锚固封堵裂隙等措施，以避免发生突水事件或降低突水事件造成的损失。Use the camera to detect all the inspection holes arranged in the mine, and detect the development and changes of the cracks in the holes multiple times at intervals. When the degree of water inrush reaches a certain level, that is to say, the threshold for the change of the fracture parameters is preset. When the change of the fracture parameters reaches the threshold range, water inrush may occur; if the monitoring results of the detection holes at different positions change regularly, and the overall fracture monitoring results show: When the cracks become wider, longer, and denser, and the degree of crack change of at least some of the detection holes reaches the preset crack parameter change threshold range, the location where water inrush may occur can be predicted, and the possible locations can be processed. Measures such as grouting anchor cables, anchoring and plugging cracks, etc., can avoid water inrush events or reduce losses caused by water inrush events.
