针对首旺煤矿回采工作面巷道围岩软弱破碎、变形量较大的问题。通过钻孔窥视分析并结合理论,对回采巷道的破坏力学机制和破坏特征进行分析。基于围岩的破坏机理和软岩巷道的支护理论和原则,确定出巷道支护的支护方式和具体参数。 Aiming at the problem of weak and broken surrounding rock of mine roadway in Shouwang coal mine with large deformation. By drilling peep analysis combined with theory, the failure mechanics and destruction characteristics of mining roadway are analyzed. Based on the failure mechanism of surrounding rock and the support theory and principle of soft rock roadway, the support way and specific parameters of roadway support are determined.
