摘要 针对大阳泉公司8120回风顺槽掘进过程中遇到的大型褶曲构造,提出超前物探+注浆加固+高预应力锚杆锚索联合支护的技术方案。实践表明:该方案能够确保巷道安全通过褶曲构造,在缩短工时的同时提高煤炭采出率,创造了巨大的经济效益与社会效益,可供类似矿山借鉴。

Abstract: In view of the large-scale fold structure encountered during the 8120 return airway excavation process of Dayangquan Coal Mining Company,the technical scheme of advance geophysical exploration+grouting reinforcement+high prestressed anchor bolt and cable joint support is proposed.The practice results show that the scheme can guarantee the safety of the roadway during the process of passing through the fold structure,shorten the working hours and increases the coal recovery rate and create huge economic and social benefits.
