技术领域technical field
本发明属于矿山地质灾害治理的一种方法，适用于建筑地基下超过30m埋深有煤矿采空区需要加固处理。The invention belongs to a method for controlling geological disasters in mines, and is applicable to goafs in coal mines with a buried depth of more than 30m under building foundations that need to be reinforced.
背景技术Background technique
地下矿产资源被开采后，对于形成的采空区处理方法主要有充填法、留设矿柱支撑法、顶板垮落法等。为了能充分回收资源，充填法在贵重或稀有金属矿产资源的开采中处理采空区使用的比较多，但充填体强度越高充填成本相应越高，即使采用充填法开采贵重或稀有金属矿产资源，充填体的围岩仍有变形破坏；在采空区留设矿柱支撑顶板岩体破坏，但随着开采扰动、地下水或岩石流变，矿柱的强度会降低，甚至破坏；顶板垮落法在煤矿开采中处理采空区比较普遍，即煤炭资源开采后，顶板岩层垮落，形成“三带”：冒落带、裂隙带和弯曲下沉带，在水文条件、地质条件、开采扰动、地形等多种因素综合影响下引起岩层和地表移动，造成道路开裂下沉，房屋倒塌等一系列岩土工程问题。After underground mineral resources are mined, there are mainly filling methods, pillar support methods, and roof caving methods for the formed goaf. In order to fully recover resources, the filling method is often used to deal with goafs in the mining of precious or rare metal mineral resources, but the higher the strength of the filling body, the higher the filling cost, even if the filling method is used to mine precious or rare metal mineral resources , the surrounding rock of the filling body is still deformed and damaged; pillars are left in the goaf to support the damage of the roof rock mass, but with mining disturbances, groundwater or rock rheology, the strength of the pillars will be reduced or even destroyed; the roof will collapse The method is more common in coal mining to deal with gobs, that is, after the mining of coal resources, the roof stratum collapses to form "three zones": the caving zone, the fissure zone and the bending subsidence zone. Under the comprehensive influence of multiple factors such as landforms and topography, rock formations and surface movement are caused, resulting in a series of geotechnical engineering problems such as road cracks and sinking, house collapses, etc.
目前对采空区处理主要有两个方面：一方面是采用绿色开采理论指导生产，即在开采设计及生成过程中对采空区进行处理，但由于开采成本、绿色开采理论的认识、环境观念等原因，该理论不能得到有效的推广。另一方面是对局部采空区注浆减沉处理，即对影响工程地基基础的部分采空区进行注浆加固，如专利(申请号：2015101306536)公开了一种采空区注浆法施工工艺，专利(申请号：2015103374519)公开了一种采空区快速注浆系统；专利(申请号：2015103369690)公开了一种采空区快速注浆系统的注浆工艺；专利(申请号：2011102394042)公开了公路采空区注浆处治方法；专利(申请号：2010101381426)公开了高速公路下伏采空区注浆投沙时浆液的制备方法。At present, there are two main aspects to deal with goafs: one is to use green mining theory to guide production, that is, to deal with goafs in the process of mining design and generation, but due to mining costs, understanding of green mining theory, and environmental concepts For reasons such as this, the theory cannot be effectively promoted. On the other hand, it is the grouting treatment for local gobs, that is, grouting reinforcement for some goafs that affect the foundation of the project. For example, the patent (application number: 2015101306536) discloses a goaf grouting method Process, patent (application number: 2015103374519) discloses a rapid grouting system for gobs; patent (application number: 2015103369690) discloses a grouting process for goaf rapid grouting systems; ) discloses a treatment method for grouting in goafs of highways; the patent (application number: 2010101381426) discloses a method for preparing grout during grouting and sand casting in goafs under expressways.
这些专利技术在采空区注浆的工艺和设备均对采空区造成岩土工程问题提出了各种解决方法，但采空区造成的岩层移动和覆岩破坏有其自身规律，对采空区注浆应该利用这些岩层移动规律，提高注浆减沉效果。The technology and equipment of these patented technologies for grouting in the goaf have proposed various solutions to the geotechnical problems caused by the goaf. Area grouting should take advantage of these rock movement laws to improve the effect of grouting to reduce settlement.
