摘要
地下矿山巷道松动圈的范围直接影响巷道支护效果,松动圈范围的测定是确定支护参数的重要参考依据。利用声波测试技术测定出云南某铜矿巷道松动圈范围为0.6-1.85m,且3个测试断面的松动圈范围呈现“大-小-大”的变化趋势,究其原因是1#断面位于断层附近,3#断面受到采动影响,通过分析得出,影响矿山巷道松动圈范围的因素主要有埋深、地质构造、开采顺序及采动作用等。
The range of broken rock zone of roadway in under- ground mines directly affects the roadway supporting effect and the measurement of broken rock zone is an important reference for determining the support parameters. The broken rock zone of roadway in a copper mine in Yunan is measured by acoustic tech- nology being 0.6-1.85 m, presenting a ＂big--small--big＂ trend for the broken rock zone range in three test sections. The reason is that the section 1# lies near faults and section 3 # is affected by mining. Through analysis, the major factors influencing the range of broken rock zone of roadway are buried depth, geological .i structure, mining operation sequence and mining affect among others.
