震后尾矿库稳定性高密度电法快速诊断技术

Quick Diagnosis Technology of the High Density Resistivity Method for Tailing Reservoir Stability in the Earthquake-stricken Area

"5.12"汶川地震震区尾矿库受地震影响较大,遭到不同程度的破坏。对四川省汉源锦泰矿业有限公司尾矿库从尾矿坝、排洪系统、企业尾矿库安全管理几个方面的现状进行逐项检查和评估,为确定尾矿库安全等级提供依据。并应用高密度电法物探设备对坝体结构安全进行了探测,分析了汉源锦泰矿业有限公司尾矿库的安全状况。基于风险评估和高密度电法的现场快速诊断结果,对尾矿库安全管理提出了技术措施。

The tailing reservoir has been destroyed in different degrees due to 5.12 Wenchuan earthquake. The status quo of tailings dams, drainage systems and tailings reservoir safety management of Siehuan Hanyuan Jintai Mining Co. , Ltd tailing reservoir was inspected and evaluated, which can provide a basis to determine the security level of the tailing reser- voir. Then the high density resistivity method was adopted to detect the structural safety of dam, and analyze the status of the security situation of the tailing reservoir in Jintai mining. Based on the risk assessment and the rapid diagnosis results by high-density resistivity method, the safety technical measures for tailings reservoir were given.
