摘要
采用高密度电法、地质雷达和瞬态瑞雷面波三种方法对江西某矿山尾矿坝进行综合勘察,结合相关地质情况和坝体结构特征,推断出隐患的性质、产状和埋深等情况;在分析尾矿坝浸润线和渗流坡降值的基础上,采用有效应力法对坝体在稳定渗流期及库内水位降落期的稳定性问题进行研究,并对尾矿坝的安全运行和使用提出建议。
The high-density resistivity method,the ground penetrating radar and the surface wave prospecting method are used to detect the tailing dam in certain mine.In consideration of dam structures and the characteristics of anomalies,the defect feature and the distribution range are found out by using the comprehensive method.The stability of the tailing dam has carried out checking calculation on the basis of analyzing seepage calculation.Some suggestions are put forward for the safe operation and the use of the tailing dam.
