摘要
根据煤岩物理力学性能、巷道收敛变形和围岩松动范围测试的数据，认定黄陵一号煤矿巷道顶板为Ⅳ类稳定性较差岩层。
The authors carry out the engineering classification of the excavation roof rock of Huangling No.1 coal mine through a series of measurement data of surrounding rock behavior over roadway.The research result shows that the roof rock of No.1 coal mine belongs to the Ⅳ rock,which is recognized as less stable rock.
