摘要
在软岩中布置溜煤斜巷,常因围岩变形影响正常使用。本文以大同煤矿集团塔山矿8369溜煤斜巷为研究对象,在巷道中采用了应力应变释放面和整体溜煤槽设计等综合技术对策,应用效果表明,能够很好解决溜煤斜巷的底鼓和大变形问题。
It is difficult to use coal slant roadway in soft rock because of the deformation of surrounding rock. In this paper the 8369 inclined lane of Tashan Mine, Datong Coal Mine Group, is taken as the research object, which uses such comprehensive technical countermeasures as the stress and strain in the roadway release slip coal groove surface and the overall design, and application effect analysis showed that the technology solves the floor heaving at the bottom of the slant roadway and large deformation of surrounding rock.
