一、问题的提出观山矿系低品位多金属有色矿山,属中、低温热液裂隙脉状填充矿床。选矿厂尾矿产出率占处理原矿的90～95%,经营十几年来,尾矿已将现有尾矿坝(占用农田40亩)全部填满。尾矿的储存和污染问题日趋严重,已形成公害,影响正常生产和有关地区的人民生命财产安全,达到了非治不可的地步。根据华东冶金地质勘探公司八一三队于六六年提交的勘探总结报告表明,该矿1号、2号
First, the issue put forward Guanshan Department of low-grade multi-colored non-ferrous metal mines, is a medium and low temperature hydrothermal fissure vein-filled deposits. Concentrator tailings output rate accounted for 90 ~ 95% of the processing of ore, operating more than a decade, the tailings of the existing tailings dam (40 acres of farmland occupied) all filled. The storage and pollution of tailings have become more and more serious. Public hazards have been formed and the safety of people’s lives and property in normal production and in the relevant areas has been reached. According to the summary report of the survey submitted by East China Metallurgical and Geological Exploration Company Team VIII-13 in 1996, the No. 1 and No. 2 Mine
