麻家梁煤矿采空塌陷后地表水对矿井安全的影响评价

Impact evaluation of surface water on mine safety after goaf Collapse collapse in Majialiang Mine

麻家梁煤矿4号煤层一、二、五采区已开采的工作面上部地表已出现地表塌陷及地裂缝,地表水有可能由地裂缝及塌陷区沿导水裂隙带进入矿井,影响煤矿的安全生产工作。针对这一情况,分析了可能造成地表水由地裂缝及塌陷区进入矿井的相关因素,结合井下实际观测成果,评价了麻家梁矿井采空塌陷后地表水对矿井安全生产的影响程度。

Surface subsidence and ground fissures have appeared in the upper surface of the mining face of No.4 coal seam in the No.4 coal seam of the Majialiang Coal Mine.Coal mine safety production work.In view of this situation,the relevant factors that may cause surface water to enter the mine from the ground fissures and subsidence area are analyzed,and the actual observation results of the underground are used to evaluate the impact of surface water on the mine safety production after the mining subsidence of the Majialiang mine.
