长河煤矿充水因素分析及防治水措施

Analysis of Water Filling Factors and Water Control Measures in Changhe Coalmine

长河煤矿为地质构造中等复杂区,其矿区地质及水文地质条件表明,地表水、直接充水含水层煤系砂岩裂隙水、老窑水、构造断裂带水都可构成该矿井开采的充水因素,且其涌水量大小与大气降水关系密切。针对矿井开采的具体情况提出了一系列的防治措施,并取得了良好的效果,对煤矿水害的防治有一定的指导意义。

The Changhe coalmine belongs to a geological structurally medium complexity area, The mining area geological and hydrogeological conditions showed that surface water, direct filling coal measures sandstone fissure water, gob water and faulted zone fissure water are all water filling factors of coal mining, and water inflow has close relations with atmospheric precipitation. In allusion to particular conditions of coal mining, put forward a series of water control measures, and good effects obtained and has certain guiding significance in coalmine water disaster control.
