摘　　要：对山浪煤矿5-304工作面直接顶页岩、老顶灰岩岩样进行圆盘劈裂、单轴及三轴压缩力学实验,分析了风氧化带内2种围岩岩样的抗拉强度和单轴、三轴抗压强度以及弹性模量和泊松比平均值与围压之间的关系。实验结果为受风氧化影响的煤矿巷道围岩支护提供基础力学参数。Through the disk splitting, uniaxial and triaxial compression mechanical properties experiments of immediate roof shale and main roof limestone in 5-304 working face, not only the tensile strength, uniaxial and triaxial compressive strength,but also the relationship between average value of elastic modulus and Poisson＇s ratio with the confining oxygenized zone were analyzed. The experiment pressure of these rock specimens from efflorescent results provided effective mechanical properties for roadway surrounding rock support in efflorescent oxygenized zone of coal mine.
