Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
A coal seam roof refers to a rock formation that is located above a coal seam, also referred to as a coal seam roof. In the process of tunneling a tunnel and mining coal, underground spaces such as the tunnel and the coal face are formed, and a coal seam roof is the roof of the spaces. The phenomena of roof rock falling, large-scale roof sinking and the like form a huge threat to personnel and equipment in the space below the roof, roof accidents are extremely easy to form, and serious casualties and equipment loss are caused.
Rock burst, also known as rock burst, refers to a dynamic phenomenon in which rock mass surrounding a roadway or working surface is suddenly and severely broken due to the instantaneous release of elastic deformation energy. The device is often accompanied with phenomena such as coal rock mass throwing, bang, air wave and the like, has extremely high destructive power, can cause accidents such as roof fall, ledge, bracket fracture and the like, and forms serious threat to personnel and equipment.
In the aspect of ensuring the safety of a roof and reducing roof accidents, a coal mine generally controls the roof structure in a roof cutting mode and the like. The common methods include hydraulic fracturing drilling, broken-roof blasting holes, dense drilling and roof cutting. Hydraulic fracturing drilling holes are generally formed by drilling a deep hole (adjusted according to actual needs) of about 30 meters from a roadway to a top plate, and injecting high-pressure water into the deep part of the drilling holes so as to cut and fracture the top plate nearby. The blast hole is broken, a deep hole (adjusted according to actual needs) with the diameter of 75-350mm and the depth of about 10m is firstly drilled on the top plate, then explosive is placed in the hole, and the surrounding top plate is broken by explosion of the explosive. The dense drilling is cut on top, need to beat a row of dense drilling to roof direction in the tunnel, the diameter is about 100mm, and the interval is about 0.5m (according to actual need adjustment), destroys the roof through a plurality of dense drilling just as in order to conveniently tear, the stamp every limit can all have a row of aperture the same, reaches accurate cutting's purpose.
The mines identified as being prone to rock burst disasters are called rock burst mines, and the mines have the characteristics of large burial depth, coal beds with impact tendencies and the like, and can be used for anti-impact methods and projects which are not available in general mines. The stress of the coal body can be detected through drilling holes, namely a drilling method, and the rock burst risk is judged. The worker transversely drives a deep hole (adjusted according to actual needs) with the diameter of about 40mm and the hole depth of about 8m into the coal body in the roadway, and the total amount of coal dust flowing out every one meter is weighed in the drilling process, so that the internal stress of the medium is judged. In addition, the pressure relief work is performed, and a large-diameter pressure relief hole is common. The diameter of the coal body in front of the working face is about 150mm, the depth is 20m (adjusted according to actual needs), a space which can be extruded is provided for the coal body, the stress environment in the coal body is reconstructed, and the pressure in the coal body is reduced.
Roof geologic structure information is also important data for analyzing disasters. The top plate endoscopic method is used for collecting part of the geological structure information of the top plate, and an endoscopic hole is commonly formed. In the tunneling process, a drilling hole is punched in the tunnel upwards at the top plate position, an endoscope is inserted from the drilling hole, and the lithology of the top plate is observed manually by using the endoscope and recorded.
It can be seen that the above engineering methods have in common that the borehole engineering is constructed downhole and an engineering log ledger is formed. In the standing book, the basic information recording conditions such as aperture, hole depth and the like are the same, and the standing book formats of the drilling engineering construction position information recorded by each coal mine are slightly different. In the tunneling process, the distance relation between the engineering position and the tunneling surface is recorded by taking the position of the tunneling surface on the same day as a reference. In the stoping process, the distance relation between the engineering position and the coal face is recorded by taking the position of the coal face on the same day as a reference. Currently, the coal mine does not contain coordinate data in the process of recording drilling engineering information. Some platforms only support manual entry of coordinate information for drilling projects, resulting in susceptibility to human error.
The application aims to provide a management system for drilling engineering and a coordinate calculation method thereof, which can calculate the space coordinate of the drilling engineering by utilizing daily recorded information of a coal mine.
In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description.

For example, (1, 12 north 1 face, left lane right side left, 3,150,16,45 meter non-productive side beyond P12), this means that No. 1 drill hole is located at a position on the left lane right side of the 12 north 1 face, hole pitch is 3 meters, hole diameter is 150 mm, hole depth is 16 meters, hole depth is 45 meters from the face, drill hole position is 45 meters non-productive side beyond P12.
The basic information setting module 102 includes a working face boundary setting sub-module and a footage inputting sub-module.
The working face boundary configuration submodule aims to optimize the setting function of the boundary line and the division thereof. After configuration, the module will show the ranges of the driving face and the extraction face on the engineering drawing, thereby providing necessary support for borehole coordinate calculation and graphic drawing.
The specific operation steps are that a user selects a coal mine working face in an installed software system and adds corresponding boundary lines. For a driving face, the boundary lines include left boundary lines and right boundary lines, and for a stoping face, the boundary lines include right roadway right sides, right roadway left sides, left roadway right sides and left roadway left sides. The user sets the position and name of the wire guide point according to the mining engineering drawing. The system then correlates the sides of the roadway where the lead points are located with the corresponding heading or extraction surface boundary lines to form a complete working surface boundary.
For example, as shown in FIG. 2, a left boundary line of the heading face is provided by adding a wire point start point coordinate A（19382680.801785804,4321679.2034839615）,B（19382681.155681357,4322820.035733477）,C（19382581.09903436,4323152.023340068） or the like to the left boundary based on the mining engineering drawing, and connecting a plurality of wire points such as ABC to form the left boundary line of the heading face. A plurality of wire points such as A1, B1 and C1 are connected to form a right boundary line of the tunneling surface by adding wire point starting point coordinates A1（19382688.948303342,4321678.248197472）,B1（19382689.570275933,4322781.004875032）,C1（19382616.76063204,4323083.277567301） and the like to the right boundary line.
As shown in FIG. 3, the boundary line of the left side of the left lane on the stoping face is set by adding wire points 1 (X: 19380261.63132117, Y: 4321541.492900674) and 2 (X: 19380260.984834984, Y: 4324165.227906144) to the left side of the left lane based on the stoping engineering drawing, and connecting the wire points 1 and 2 to form the boundary line of the left side of the left lane. The drawing mode of the boundary lines of the left lane right side of the stope, the right lane left side upper and the right lane right side upper is the same as that of the left lane left side upper.
The footage input submodule is used for maintaining the progress of the working face in the mining process. The system provides a footage input function, a user can input the daily mining progress of a working face by using the system, for example, a stope is recorded in the form of '2024, 08, 11, 20 minutes and 33 seconds, a left roadway is 3m, a right roadway is 3 m', a tunneling face is recorded in the form of '2024, 08, 12, 20 minutes and 33 seconds, and 10 m', and the system can calculate the total footage of the left roadway and the right roadway and the total footage of the tunneling face at the current time according to the time after the system is input.
The drilling engineering coordinate calculation module 103 combines the recorded information such as the distance between the drilling hole and the working surface with the position relationship of the current working surface to locate the position of the roadway where the drilling hole is located, so as to obtain the coordinate position of the drilling hole.
The visual display module 104 of the map on the drill hole automatically draws drilling cuttings holes, pressure relief holes and blasting holes on the mining engineering map based on the GIS geographic information technology for visual display.
Specifically, the position point of the drilling hole is determined by using the position relation of the dotted line, the direction of the engineering information hole on the graph is determined according to the drilling angle and the mining direction, and finally the graph on the drilling hole is visually displayed according to the hole depth.
In addition, in some embodiments, the system further comprises a drilling engineering information query module for displaying drilling engineering information entered by the drilling engineering information after selecting the belonging working surface, roadway, date and shift. And the drilling engineering data export module is used for exporting drilling engineering information, coordinate calculation results and visual display diagram data.
