半煤岩巷道围岩变形机理及控制技术研究

基于潞安集团蒲县隰东煤业公司半煤岩回采巷道合理支护的问题,运用现场实测、数值模拟和理论分析相结合的方法,研究了半煤岩回采巷道变形破坏的机理,提出了半煤岩回采巷道支护对策和方案,确定采用锚网索+钢筋托梁联合支护技术,并确定了联合支护的参数和工艺。可为其他具有相似地质条件的巷道支护设计提供参考和借鉴。

Study on the Gateway Rock Distortion Mechanism and Control Technology of Semi Coal and Rock

Based on the problem of gateway support of semi coal and rock gateway at mining area of shanxi lu'an group pu xian xi dong coal Co.,Ltd,the deformation and failure mechanism of semi coal and rock roadway was analyzed by adopted the method of combining the observation and numerical simulation and theory analysis,then the plan of the gateway supporting and the unite supporting technology was put forward,which combined the bolt,anchored cable,metal mesh and reinforced beam,and the gateway supporting process and parameters was determined by theory analysis.This study can provide the reference for other main track roadway supporting of similar conditions.
