摘　　要：本文对砚北矿高地压、大跨度、倾斜特厚煤层巷道破坏原因进行了详细分析 ,探讨了此类巷道的压力分布规律 ,并通过现场量测 ,证实了压力分析的正确性。在此基础上 。This thesis analyses the reasons of the destruction of Yanbei colliery high pressure large span inclined thick coal seem roadways and probes the law of pressure distribution of this kinds of roadways. Through underground data, the rightness of pressure distribution is tested, based on the analysis, the proper supporting measures are represented.
