葛泉矿东井9^#煤带压开采研究

Gequan East Mine 9^# Coal Pressure Mining Study

以葛泉矿东井水文地质条件为基础,结合突水系数理论和涌水量计算理论,通过实施物探、钻探、水闸门、底板注浆加固、底板突水自动识别系统和突水水源判别系统等一系列工程措施,总结出一整套高承压岩溶含水层上带压开采下组煤的防治水技术,分析得出葛泉矿东井下组煤带压开采的可行性方法。

The article is based on hydrogeological condition of Gequan East Mining, combing with theories of the inrush coefficient and yield quantity, through implementation of geophysical prospecting, drilling, water gate, backplate grouting reinforcement, inrush water resources of automatic identification system and other engineering measures, concludes a whole set of high--pressure karst aquifer pressure on the group of coal mining under the control of water technology and achieves the feasibility of mining method which mining of pressure underground coal.
