摘要: 针对某尾矿坝特定工况条件,通过现场测震实验,采用溃坝风险分析、渗流模拟、稳定性分析等多种方法,研究在爆破震动波作用下的尾矿坝稳定性问题,确定影响尾矿坝安全的主要因素,判明在不同工况条件下尾矿坝稳定性的安全边界条件。结果表明:在拟定震动条件下的尾矿坝振动速度为12.0 cm/s时已没有安全储备,安全允许爆破振动速度应控制在6.0 cm/s以内。

Abstract: According to the working conditions, the site vibration test method, dam risk analysis method, seepage simulation method and stability analysis method are adopted to analyze the tailings dam stability under the action of blasting vibration waves, and determine the main factors that affect the safety of tailings dam, and determine the security boundary conditions of tailing dam under different operating conditions. The research results indicate that, under the proposed vibration conditions the tailings dam is not safe when vibration velocity is 12 cm/s, and 6.0 cm/s is the maximum security allowed vibration velocity.
