煤矿露头区采掘工作面的防治水探析

Analysis of Water Prevention and Control at Mining Workface in Outcrop Area in Coal Mine

露头区的围岩较为软弱容易破碎,且在基岩面上方通常都是松散的粘性土隔水层或直接为含水砂层,使得露头区的采掘工作面很有可能存在地表水体,对采掘工作造成一定的安全隐患。叙述了煤矿采前、采中需进行的地质及水文地质工作,探讨了露头区采掘工作面的综合防治水措施。

Surrounding rock of outcrop area is relatively weak and easily broken, usually, there is loose clay aquiclude or waterbearing sandy ground above the bedrock surface, therefore the mining working face of outcrop area is very likely in the surface waters, which caused certain security hidden danger for mining work. This paper described geological and hydrogeological work before mining, in-process mining, discussed comprehensive water prevention and control measures.
