新疆硫磺沟煤矿水害分析与治理

Water Damage Analysis and Governing in Liuhuanggou Coalmine, Xinjiang

为了探究新疆硫磺沟煤矿矿井涌水量突然增大的水害问题,根据矿井开采历史状况、地表头屯河河流充水和相邻矿井涌水情况,采用综合分析法详细讨论了矿井充水的主要影响因素,分别评价了老窑水、地表水和相邻矿井水与该矿目前矿井涌水量之间的关联程度。研究结果发现,矿井涌水量的增减受浅部东翼老窑水的制约,涌水通道为与相邻矿井沟通的巷道和头屯河河床塌陷所形成的通道,最终充水水源为头屯河河水。根据分析研究结果,提出了采用直接开挖至9-15煤层底板后再回填压实的具有针对性的治理该矿井水害的相关建议和措施。

To probe into suddenly increased mine water inflow damage issues in the Liuhuanggou coalmine, Xinjiang, based on mining historic status, surface Toutunhe River filling and neighboring coalmines water gushing instances, through integrated analysis discussed mine water filling main impacting factors in detail. Correlation extent between gob water, surface water, neighboring mine water and the coalmine present water inflow has been assessed respectively. The result has shown that the fluctuating of mine water inflow is conditioned by shallow part east wing gob water. Water gushing is through channels formed by roadways communicated neighboring coalmines and Toutunhe River channel subsiding, the final water filling source is the river water. Based on analyzed results, targeted coalmine water damage governing related suggestions and measures to use direct excavating to coal Nos. 9~15 floors, then back filling and compacting put forward.
