资源整合煤矿老空水致灾因素普查与治理

Investigation of Gob Water Disaster-causing Factors and Its Control in Resource Integration Coal Mine

煤炭资源整合矿井开采时间长,废弃老窑及采空区多,存在着采空区资料不清、积水情况不明等问题,资源整合煤矿防治水形势严峻。以山西和尚嘴煤业为例,分析了矿区水害特点,采用井上下物探与钻探综合探查手段,查明了隐蔽致灾因素,制订出疏排放采空区积水的方案,总结了隐蔽致灾因素治理效果。研究表明:地质与水文地质资料分析是资源整合矿井水害隐蔽致灾因素普查与治理的重要基础手段,地面物探结合井下物探是解决多层采空区积水探查的较好方法,钻探结合物探技术是疏放多层采空区积水较好的途径。

At present, the resource integration coal mines are faced with a serious situation in mine water prevention due to their long mining time, more abandoned pits and mined-out areas, unclear gob data and unknown gob water accumulation. In this paper, analysis was made on the characteristics of water disasters in this mining area by taking Shanxi Heshangzui Coal Mine as an example, the hidden factors causing water disasters were found out by adopting both the surface and underground physical prospecting and exploratory boring methods, the gob water drainage schemes were worked out, and the control effect of the hidden disaster-causing factors were summarized. The study showed that the analysis on the geological and hydro-geological data was the basic and important method for the investigation and control of the hidden factors causing water disasters in the resource integration coal mine, the combination of the surface and underground physical prospecting was a better method for prospecting multilayer gob water accumulation, and the combination of exploratory boring and physical prospecting was a better way to drain multilayer gob water.
