摘要:
通过开展岩石静力学试验获取岩石力学参数对于优化露天台阶爆破方案和改善爆破效果具有重要意义。以国内某露天铜矿矿岩为研究对象,使用冲击动能为0.735 Nm的HM-82L型回弹仪对岩体的力学特性开展原位试验研究。此外,在现场钻取岩芯制备标准试样,使用SET-PLT-02型声波测试仪进行波速测试,并基于MTS-322液压伺服力学试验机开展系列力学试验。现场回弹试验结果表明:矿区南端斑岩的回弹值大于北端矽卡岩的回弹值,且回弹值随岩体风化程度的增大而逐渐减小;室内物理力学试验结果表明岩体波速、单轴抗压强度、弹模与回弹值之间的变化规律基本一致,拟合曲线表明波速、单轴抗压强度与回弹值之间呈线性正相关关系,而弹模与回弹值之间呈指数相关关系,拟合相关系数说明利用回弹值估测岩体波速和基本力学参数是可靠的。研究成果为快速可靠地获取该露天铜矿矿区岩体的基本物理力学指标提供了可靠的技术途径。
