摘要：The mining roadway stability is the directly major problem facing in the oil shale upward mining, in order to guarantee the stability of the roadway, we need to determine the reasonably position of the roadways. To this end, this article analysis the movement rule after mining the coal 2 and the deformation and failure state of oil shale 2 with field observations and numerical simulation analysis. Come to the conclusion that the moving boundary strata is about 15m, the impact angle is about 55 degrees, then, we determine the reasonable position of mining roadways.
