摘要
结合陈四楼煤矿 2 10 2机巷的具体地质条件 ,介绍了大埋深沿空掘巷锚杆支护的设计思路、设计参数。工程实践表明 :应用锚杆支护 ,能显著改善围岩的稳定性 ,取得良好的支护效果。
This paper introduces thinking and parameter of design for bolt support with covering deeply on road driving next goaf with specific geological condition of 2102 roadway of Chensilou coal mine.This practice explain:it can imprve stable of rockstrata and there is a good result to support with bolt support.
