随着煤层巷道的开挖,巷道围岩的稳定性一直是煤矿企业的生产难题。利用力学理论和实地勘测结合法对林西矿4#煤层巷道围岩变形特征和应力分布规律进行分析,得出了较为准确的计算结果,为今后的煤巷支护工作提供了科学的参考数据。
With the excavation of coal seam roadway, the stability of roadway surrounding rock has been the production problem of coal mine enterprises. By using mechanics theory and field survey and combination method, the deformation characteristics and stress distribution of surrounding rock in No.4 coal seam roadway in Linxi Mine are analyzed, and more accurate calculation results are obtained, which provides scientific reference data for coal tunnel supporting work in the future .
