许多露天矿的排土工程量相当大,所需费用很多。例如,乎拉尔石棉生产联合公司所属露天矿每年堆入废石场的岩石和选矿尾矿超过1.5亿吨,仅其中一个排土场(东排土场)的排土量已达15亿吨。这个高90米的排土场占地近700公顷。大型露天矿的年排土费用可高达1千万卢布,然而研究工作与实践都证明,如果排土场的参数和排土顺序在空间和时间上都达到最佳化,则排土费用可
Many open-pit mines have a large amount of earthwork and require a lot of costs. For example, more than 150 million tons of rocks and beneficiation tailings were piled into the waste rock field each year in open-air mines belonging to the Al-Asilar Asbestos Production Union, leaving only 1.5 billion tons of earth mined in one of the dump sites (east dump) . This 90-meter high dump covers an area of nearly 700 hectares. Large-scale open-pit mines can cost up to 10 million rubles annually. However, both research and practice have proved that if the parameters of the dump and the order of soil dumping are optimized both in space and time,
