摘要
从悬伸岩层对煤体上覆岩层作用的角度,分析了支承压力分布规律的形成和小煤柱护巷的理论依据,并对小煤柱护巷条件下急倾斜与倾斜煤层中巷道的支护方式进行了一定程度的探讨。
According to the action of cantilever rock seam on the overly- ing strata of coal body, the paper analyses the distribution rule of abutment pressure and the theoretical basis of narrow pillar drift and exploies the sup- port type of drifts in inclined and steep inclined coal seam under the condi- tion of narrow pillar drift.
