“三软”近距离薄煤层穿层回采技术的实践

Practice on Stoping Technology across Coal Strata in "three Soft" Thin Seam at Close Range

针对双龙矿业公司衰老矿井和煤层赋存实际情况,进行工程地质和围岩应力调查研究,在论证分析的基础上,提出了"三软"近距离薄煤层穿层回采优化方案,借助于完善的安全技术措施,在实践中取得了良好的技术经济效益,并实现了安全生产。

Aiming at the existing conditions of old mines and seam occurrence in Shuanglong Mininglndustry Co. , the author has posed an optimum plan for stoping across coal strata in ＂three soft＂ thin seam at close range after survey of engineering geology and adjoining rock stress, which has proved safe and productive.
