Tailing Dam Design In Gold Mining

Tailing Dam Design In Gold Mining

Tailing Dam Brief Introduction

Tailing Dam refers Taniguchi damming or enclosure constructed of metal or nonmetal mines to be stockpiled ore tailings discharged after sorting or other industrial waste sites. Tailing Dam is a man-made debris flow with high potential sources of danger, there is a risk of dam failure, once the accident, likely to cause serious accidents.

Gold Run Mining Tailing Dam Situation

Tailings tailings facility is one of the important gold mine production safety. In recent years, due to the rapid development of the gold industry, the processing capacity of the mine concentrator growing wider, the corresponding emissions tailings also increasing, according to incomplete statistics, the existing Gold Mining Tailing Dam reached 368. 20 more provinces: Shandong, Henan, Hebei, Liaoning, Shanxi, Jilin, Inner Mongolia, Xinjiang, of which there are more than 80 seats Shandong Province). Due to the characteristics of the gold industry beneficiation process, Gold Mining Tailing Dam dam dam forms stacked multi-use upstream method, generally Gold Mining Tailing Dam including the initial dam and post-dam in two parts.

Gold Mining Tailing Dam features

Due to the special nature of the industrial production of gold, the formation of some of the features of its tailings.

Gold Mining Tailing Dam are often located in remote mountainous areas, select the tailings site, often accounting for less farmland, most terrain conditions are poor, narrow valley gorge, steep slopes, small storage capacity, small flood storage capacity, relatively large catchment area so Gold Mining Tailing Dam is relatively high. Arid regions such as the concentrator has backwater requirements, long-term high water level inside the dam, built in the formation of artificial high-potential “debris flow”, so the flood control design Gold Mining Tailing Dam has special requirements.

Due to the characteristics of beneficiation process, the use of flotation, flotation and cyanidation or cyanidation process of gold, etc., and in recent years to improve gold recovery, increase the grinding fineness, its tailings Liaoduo 200 Head up to 70% -95% Gold Mining Tailing Dam dam to bring some difficulties, often likely to cause the accumulation of Gold Mining Tailing Dam high saturation line, the emergence of the outer slope of the dam seepage, piping, flow and soil swamping foot dam . Adverse factors to Gold Mining Tailing Dam stability.

With the expansion of production scale, the sharp increase in gold concentrator tailings discharged and “three wastes”, such as flood control and safety, environmental protection and land, reclamation and other issues are on the agenda. Safety and environmental protection increasingly heavy workload.
