摘 要:以龙煤矿业集团鸡西分公司荣华立井煤矿西主运输维修大巷为研究对象,根据西主运输大巷围岩物理力学试验及钻孔窥视仪和地质探测仪松动圈测定结果,确立巷道支护结构和支护参数。利用COMSOL有限元数值模拟软件进行数值模拟计算,论证了"锚网索喷+U型钢可伸缩性支架"联合支护技术对于深部软岩巷道稳定性控制具有良好的效果。In this paper, the transportation roadway of Ronghua shaft coal mine of Jixi Branch Company in Longmei Mining Group is the engineering instance. According to the physical mechanics test of surrounding rock and the determination of loose circle of the west main haulage roadway, the roadway support structure and support parameters is established. The simulation software of COMSOL is used for the numerical simulation, thus it is demonstrated that the combined support technology of "cable anchor and shotcrete +U type steel bracket " is the effective method to control the stability of deep soft rock roadway.
