声波法测试缓倾斜层状岩体松动圈的应用研究

摘要

为准确探测缓倾斜残矿层状岩体松动范围,依据声波测试岩体松动圈的原理及层状岩体的力学特性,并结合平里店矿区1058试验采场的工程地质条件、开采现状及其层状岩体松动圈的形成机理,合理布置岩体松动圈测试点；然后采用声波测试方法对缓倾斜残矿层状岩体松动圈范围进行探测；最后对声波测试数据进行判读、分析,确定残矿层状岩体松动范围.研究结果表明:声波测试方法能够科学的、合理的探测层状岩体松动圈大小,具有很好的工程实用性.%This study attempted to evaluate the feasibility of sound wave method in detecting the loose circle of layered rock masses in gently inclined residual ores, with performing a case study for Pinglidian mining area 1058. Test points were set with consideration of the engineering geological condition, current status of mining,and the mechanics characteristic of layered rock mass;Then,the sound wave test method was applied to the study area;Finally the loosen zone was defined by interpreting and analyzing the testing data. The results show that acoustic testing method can detect layered rock mass loose circle size reasonably and scientifically with good engineering applicability.
