采用尾砂充填采矿法的矿山存在问题之一为溢流细砂不能筑坝,需人工采石筑坝,这将消耗大量人力、物力,以焦家金矿为例,每年需筑坝费50万元;而且风干了的细砂,对下风向造成公害.故综合利用尾砂是有较大的现实意义和经济价值.本文试就在实验室试验及小型工业试验的基础上,对焦家金矿的尾砂综合利用问题进行探讨,以求解决该矿在溢流尾砂上存在的问题.
One of the problems in mining with tailings-filling mining method is that overflow fine sand can not be dammed and artificial quarrying and damming are required. This will consume a large amount of manpower and material resources. Taking Jiaojia Gold Mine as an example, annual construction cost of 500,000 yuan ; And dried sand, the wind downstream caused by public hazard.Therefore, the comprehensive utilization of tailings is of great practical significance and economic value.This paper is based on laboratory tests and small industrial tests, the Jiaojia Gold Mine Tailings comprehensive utilization of the issue to explore in order to solve the mine in the overflow tailings on the existing problems.
