摘要 根据矿区的地质和水文地质资料,分析了118工作面发生突水的背景、原因、通道、水源等,得出洛河组砂岩裂隙含水层向宜君组砾岩与下伏泥岩形成的顶板离层空间充水是其主要水源,提出可通过破坏离层封闭性和超前疏放离层水等途径来预防离层水突水事故的发生。 Based on the geological and hydrogeology data, it analyzed the background, cause, channel, and water sources of water in- rush in No. 118 working face. It obtained that roof separation space formed between Yijun group sandstone and underlying conglomerate and mudstone, water filling happened in this space from Luohe group sandstone aquifer, and it was the main water source. It proposed that water inrush accident of separation layer water could be prevented by destroying the closeness of separation layer and discharging separation layer water in advance.
