摘要
通过对深部巷道矿压显现特点、巷道变形规律、巷道破坏机理及巷道支护原理进行分析,根据现场实际地质条件提出了深井巷道矿压的控制应该充分发挥以锚杆为主体,以锚索、铁网为辅的新型支护以及锚喷、锚索、锚网等联合支护形式;并根据实际情况确定具体支护参数。
Through deep roadway characteristics of the rock burst,deep mine pressure behavior,roadway failure mechanism and roadway support principle are analyzed.According to the actual on-site geological conditions,some measures are pointed out,the pressure control in deep mine tunnel should give full play to the main anchor for a new type of support as well as combined support form with spray anchor,cable,wire mesh.The specific support parameters are determined according to the actual conditions.
