摘要
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 seam roadway excavation, the surrounding rock stability is an problem in the coal mine enterprisers production. In this paper, using the theory of importand mechanics and field survey method, Linxi Mine 4^# coal seam roadway surrounding rock deformation characteristics and the law of stress distribution are analyzed, the more accurate results are obtained, the important reference data are provided for the future coal roadway work.
