摘要
介绍了在煤矿软岩类掘进过程中,采用掘进工作面护网对暴露煤体进行全断面防护,有效增加掘进工作面有限空顶范围内的安全系数的设计方案及实施方法。
This paper introduces the practice in which protective mesh is used in heading faces in soft strata in coal mines to cover the exposed coal rib/roof entirely so as to improve the safety coefficient in the faces. This provides safer working environment to the heading crew members
