摘　　要：针对综放支架回采过程中固体构件损伤和液压系统泄漏导致的端面煤岩体冒顶片帮问题,综合现场调研、理论分析、模拟试验、现场应用实测等方法,结合共因失效计算模型,提出综放支架固液两相严重故障同步检测技术,系统研究了综放支架固体构件超声相控阵无损探伤原理和液压系统YHX型无损检测原理。综放支架固液两相严重故障同步检测技术在同忻煤矿8107综放面试验成功,故障检测维修后,端面冒顶片帮事故得到有效控制。Aiming at the rib and roof accidents in the process of extraction caused by component damage and hydraulic leak, combining with field investigation, theoretical analysis, simulation test, field monitoring and CCF calculation model, the synchronization testing technology based on solid-liquid serious failures of hydraulic supports in fully-mechanized caving face was put forward. Then, the nondestructive testing mechanism of ultrasonic phased array and YHX hydraulic leak were researched systematically. This technology have been used in the Tongxin Coal Mine 8107 workface successfully, and the rib and roof accidents are controlled well.
