半煤岩巷道为开采薄煤层煤炭资源而设计的,深入剖析了半煤岩巷道在围岩结构、力学性质及围岩变形、破裂等层面上的不连续性,将半煤岩巷道帮部煤体与岩体交界面定义为煤岩体结构面,研究了基于结构面粗糙度系数估算的煤岩体结构面强度以及相关材料参数选择方法。研究成果对于半煤岩巷道煤岩体结构面稳定性研究及巷道围岩控制具有重要意义。
Semi-coal rock roadway is designed to mine the coal resources of thin coal seam. The semi-coal rock roadway in-depth analysis of the surrounding rock structure, mechanical properties and the surrounding rock deformation, rupture and other aspects of the discontinuity, the semi- The interface between body and rock mass is defined as the coal and rock mass structural plane. The strength of the structural plane of coal and rock mass based on the roughness coefficient of structural plane and the selection method of related material parameters are studied. The research results are of great significance for the study on the stability of coal and rock mass face and the surrounding rock control in semi-coal rock roadway.
