【摘要】：补连塔煤矿为减少矿井污水外排、充分利用水资源,将矿井污水注入采空区进行污水净化、储水和复用,因采空区采用隔离煤柱、防水密闭墙进行了封闭,为保证采空区储水和回采区域的安全生产,在通过建立物理、数学模型对隔离煤柱、密闭墙、围岩强度和煤体裂隙发育情况以及采空区水体性质和水压大小进行研究的基础上,分析了采空区储水的安全性,确定了采空区储水的限制水位和安全警戒线。
[Abstract]:In order to reduce the drainage of mine sewage and make full use of water resources, the mine sewage is injected into the goaf for sewage purification, water storage and reuse. Because the coal pillar is isolated in the goaf, the waterproofing and sealing wall is closed. In order to ensure the safe production of water storage and mining area in goaf, on the basis of establishing physical and mathematical models to study the isolated coal pillar, the closed wall, the strength of surrounding rock and the development of fissure of coal body, as well as the nature and water pressure of water body in goaf. The safety of water storage in goaf is analyzed, and the limited water level and safety warning line are determined.
