摘要
补连塔煤矿在五盘区12煤综采工作面巷掘进期间揭露了冲刷带,由于冲刷带分布延伸情况不明确,为了优化生产组织保障安全高效生产,保证工作面正常回采,补连塔煤矿对冲刷带进行了探测分析,并根据实际情况确定工作面最终的布置形式和生产方式。实践证明,该技术降低了生产成本及安全风险,最大限度地回收了煤炭资源。
During the excavation of fully mechanized working face in No. 5 panel of No. 12 coal seam, the scouring zone was revealed. As the distribution of scouring zone is not clear, in order to optimize production organization, ensure the safe and efficient production, and guarantee the regular coal recovery, the scouring zone is detected, and the final layout of working surface and production methods are determined according to the actual situation.
