摘要
平禹一矿水文地质条件极其复杂,煤矿开采受煤层底板灰岩强含水层岩溶承压水严重威胁。为解放受水害威胁的煤炭储量,在分析矿井水害成因的基础上,采用了井下物探与钻探相结合,浅部帷幕注浆截流、井田疏水降压和局部底板注浆加固相结合,堵水和排水相结合等措施,对灰岩水害进行了综合防治,取得显著效果,实现了矿井的安全高效生产。
Hydrogeological condition is very complex in Pingyu No.1 Coal Mine,the coal mining is seriously threatened by confined water of the coal floor karst limestone strong aquifer.For liberation the coal reserves threatened by water,through the analysis of reason for water disasters,the methods of ＂ combination of underground geophysical exploration and drilling exploration,combination of shallow heavy curtain and grouting for water-blocking,hydrophobic decompression in coalfield and floor grouting reinforcement in local region,combination of water plugging and drainage＂ and so on,were applied to control water disasters comprehensively.Practices has shown that the application of theses methods has significant effects,has realized safe and high-efficiency production of the mine.
