摘要
坪上煤矿目前开采的山西组下部3号煤层受底板奥陶系灰岩水突水威胁。以地下水赋存特征、隔水层隔水性能、断裂构造导水性、陷落柱导水性等为主要研究对象,采用定量、定性及理论与实际相结合的方法,研究和评价了3号煤层承压开采突水危险性,为矿井安全生产及水害防治提供了科学依据。
No.3 coal seam lied in the bottom of Shanxi Formation in Pingshang Coal Mine is threatened by limestone confined water. Based on the analysis of the occurrence characteristics of groundwater, waterproof performance of water-resisting layer, hydraulic conductivity of fault structure and collapse column, this paper studied and evaluated water inrush danger caused by mining above aquifer in No.3 coal seam by using quantitative and qualitative method and method of integrade theory with practice to offer a scientific basis for the mine safety production and prevention and control of water disasters.
