陈四楼矿迎采动沿空掘巷技术研究及应用

ccording to coal pillar crusher and violent strata behaviors of surrounding rock of roadway in engineering practice of roadway driven along next gob and heading adjacent advancing coal face on track transportation tunnel of 2409 coal face on Chensilou coal mine, Stability of rock around roadway is analyzed and this article considers that the key of the problem is special schedule and spatial location. This article puts forward a supporting thought by strengthening the roof and coal pillar and primary support.Pertinence supporting parameters has been designed for the complex geological condition of 2409 track transportation tunnel. High strength anchor bar, the steel band of model M, metal net and anchor craning beam joint support has been used in the project. Engineering practice show that maintenance result of roadway is good.
