俯斜一次采全高巷道围岩变形测试结果分析

Test Result Analysis of Rock Deformaion in Oblique Simultaneous Mining All High Roadway

对张集煤矿1111(3)俯斜一次采全高巷道围岩变形测试结果进行分析,以此掌握该面矿压超前影响范围、超前支承压力的峰值范围及巷道围岩变形情况,为合理确定巷道加强支护形式和超前支护距离提供依据。

This paper analyzes rock deformation tested result in 1111(3) oblique simultaneous mining all high roadway, in zhangji coal mine,so, lead effect scope of rock pressure,peak value scope of lead abutment pressure and rock deformation are known, it provides rational basis for strengthening supporting form and lead supporting distance.
