摘要
岩体完整性对井下岩体变形及巷道失稳破坏起着重要作用,其准确分析对开采设计、支护治理具有重要意义。针对井下矿山的特点,利用声波钻孔测试技术对现场钻孔进行声波测试,与室内实验室岩石的声波测试结果对比,对某铁矿的岩体完整性做出评价。研究表明:声波钻孔测试技术实际应用效果良好,可以对钻孔所揭露的岩体完整性进行定量分析,其声波测试结果较为准确的确定了研究范围内的岩体完整性系数,为矿山设计提供依据,可为类似矿山提供借鉴。
The integrity of rock mass plays an important role in underground rock mass deformation and roadway instability failure.In view of the characteristics of underground mines,acoustic testing technology is used to carry out acoustic testing of field boreholes.The research shows that the acoustic borehole test technology has a good practical application effect,and it can carry out quantitative analysis on the integrity of rock mass exposed by the borehole,and the acoustic test results can determine the integrity coefficient of rock mass within the research scope more accurately,providing a basis for the mine design and a reference for similar mines.
