爆破能量传播方向与边坡夹角对露天矿边坡稳定性的影响

摘要

A large number of blast site slope failure phenomena show that the energy propagation direction of the blast damage caused by the differences with the study of slope protection is important. Previous studies on the energy propagation direction of blasting and opencast mine slope stability are less. But the study of the relationship between them is meaningful to actual works on theoretical and practical implications. In this paper,bench blasting ultrasonic-testing research on the Company State Power Ping Zhuang West Opencast Mine is firstly introduced, and followed by compare analysis to the experimental data,at last we get access to the relationship of the angle and injury from blas-ting site geological under the conditions,so that we could get more accurate forecasts and judgments about mine blas-ting damage to production resulting slope.%大量爆破现场边坡破坏现象表明爆破能量传播方向与所造成损伤的差异性研究对边坡保护很重要,以往对爆破能量传播方向对露天矿边坡稳定性的研究较少,而研究这一关系对实际工程有理论和实际意义.首先对国电平庄西露天矿台阶爆破进行超声波检测试验研究,再对试验数据进行对比分析,获取该爆破场地地质条件下的角度与损伤关系,对该矿区爆破生产产生的边坡损伤进行较为准确的预测及判断.
