【摘要】：補連塔煤礦為減少礦井污水外排、充分利用水資源,將礦井污水注入采空區(qū)進行污水凈化、儲水和復用,因采空區(qū)采用隔離煤柱、防水密閉墻進行了封閉,為保證采空區(qū)儲水和回采區(qū)域的安全生產,在通過建立物理、數(shù)學模型對隔離煤柱、密閉墻、圍巖強度和煤體裂隙發(fā)育情況以及采空區(qū)水體性質和水壓大小進行研究的基礎上,分析了采空區(qū)儲水的安全性,確定了采空區(qū)儲水的限制水位和安全警戒線。
[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.
