凤阳山矿区水文地质特征及充水因素分析

Hydrogeological characteristics and water filling factors in Fengyang mountain mining area

依据凤阳山煤矿以往地质勘查及煤矿开采成果资料,对矿井水文地质特征及充水因素进行了分析,认为矿井充水水源主要是大气降水沿塌陷裂隙渗入,二1煤层直接顶板砂岩裂隙水、底板太原组上段岩溶裂隙水的水量不大,间接充水水源是寒武系岩溶裂隙水、老空区积水和矿井排水。基于凤阳山煤矿水文地质特征,从矿井充水因素、充水通道进行分析,为煤矿的安全生产提供了思路。

On the basis of the Fengyang coal mine coal mining results and previous geological exploration data, the hydrogeological characteristics and mine water filling factors are analyzed that the mine water sources are mainly precipitation collapse fissures along the infiltration of two 1 coal seam roof and floor sandstone fissure water is not water in upper Taiyuan formation of karst fissure water, indirect charge water is the Cambrian karst fissure water, gob water and mine drainage. Based on the hydrogeological characteristics of Fengyang mountain coal mine, this paper analyzes the factors of water filling and water filling in coal mine, and provides an idea for the safety production of coal mine.
