Analysis on the application prospect of ASR in-situ stress measurement method in underground mine

  • 摘要: 现今地应力状态是井下矿山建设、巷道稳定性分析和冲击地压(煤与瓦斯突出)预测等方面的重要基础数据。目前井下矿山地应力测试主要以空芯包体解除法为主,实践中发现空芯包体解除应力计安装过程中,易出现不能与孔壁完全黏贴的情况,导致测试成功率较低且劳动强度较大。文章介绍了一种基于定向岩芯卸荷后非(滞)弹性恢复变形测量的近原位地应力测试方法(简称ASR法),并通过与水压致裂地应力测试结果对比,验证了ASR地应力测试方法的有效性。ASR法的可重复性结果表明,同一测点ASR地应力测量结果平均差系数最大为6.29%,验证了ASR地应力测量方法的可靠性。预期ASR法以其安全、高效且不受测量深度和测试环境限制等优点,在井下矿山地应力测试中具有广阔的应用前景。
