摘　　要：针对深部巷道变形失稳的问题,利用数值分析软件对我国煤矿开采中的深部巷道支护形式进行简要分析,认为其主要原因是巷道支护形式及支护强度不能遏制深部高应力对巷道浅部围岩的破坏作用,并提出采用环形全断面支护方式,加强深部巷道围岩控制,大幅度降低巷道底鼓量,保证巷道正常使用,减少巷道维护费用,提高煤矿生产的经济效益。Based on deep roadway deformation instability problem, deep roadway support form of coal mining in our country was analyzed by numerical simulation software, it was considered that the mine reason of roadway damage was that the supporting method and strength cannot prevent the high stress damage to the surrounding rock of deep roadway, the whole section supporting method to improve the surrounding rock control of deep roadway was put forward, the technology can strengthen the control of deep roadway surrounding rock, greatly reduce the floor heave, ensure the roadway safely using, reduce the maintenance costs of roadway and improve the economic benefits of mine.
