月山铜旷是一个有近20年开采历史的矿山,主要生产矿区铜牛井,每年生产排出的尾砂达7.5万吨,目前堆存量达110多万吨,占地141亩。堆砂面已接近溢洪口,威胁坝体安全,而坝外有村庄两个,良田数百亩,一旦崩坝,后果不堪设想。现有的尾砂库坝顶已达到最大设计高度,无法再加高。为确保矿山生产,安徽省冶金厅已正式下文要求本矿在近两年内速建一座新尾砂库。据初步估算,新库需占地150亩,投资300—350万元,根据矿山经济承受能力,面临重重困难。为此,我们经过多方考察研究,认为利用尾砂制砖可以达到不建新库的目的。 Yueshan Copper Kuang is a mine with nearly 20 years of mining history. It mainly produces copper cow wells in the mining area. The tailings produced and discharged each year reach 75,000 tons. At present, the stockpile amount to more than 1.1 million tons and covers an area of ​​141 mu. Sand pile surface is close to spillway, threatening the safety of the dam, while there are two villages outside the dam, farmland hundreds of acres, once the collapse of the collapse, the consequences could be disastrous. The existing tailings dam crest has reached the maximum design height, can not be increased. In order to ensure mine production, the Metallurgical Department of Anhui Province has formally requested that the mine speedily build a new tailings pond within the past two years. According to preliminary estimates, the new library needs an area of ​​150 acres, an investment of 300-350 million, according to the economic affordability of the mine, facing numerous difficulties. To this end, after many investigations and studies, we believe that the use of tailings brick can achieve the purpose of not building a new library.
