Based on the basic principles of rock broken zone testing technology, the broken rock zone of roadway was sur-veyed by borehole TV, the surrounding rock failure mechanism of deep-buried roadway was researched and the failure modes and rules of surrounding rock were analyzed.The results can provide basis for optimizing supporting parameters of deep-buried coal roadway.%根据围岩松动圈测试技术的基本原理，研究了胡家河煤矿深部厚煤层巷道围岩破坏机理，采用钻孔窥视仪探测了巷道松动圈范围，并分析研究了围岩的破坏模式及规律，为优化深埋煤层巷道支护参数提供了依据。
