解决煤炭工业合理利用燃料资源的问题与综合加工利用选煤矸石有关。煤炭开采量的增加,矿山地质条件的恶化,采煤技术和工艺的变化等导致煤炭入洗量的增加,以及矿物成分含量的提高。这两个因素造成了选煤矸石量的增长。1984年,苏联煤炭工业部属企业重力选矸量为10400万吨,浮选矸石为800万吨。各煤炭基地运输、堆放和贮存矸石的费用:重选矸石为0.45—0.55卢布/吨,浮选尾矿为1卢
Solve the coal industry, the rational use of fuel resources and the comprehensive utilization of coal gangue processing. Increased coal mining, deteriorating geological conditions in mines, coal mining technology and process changes lead to an increase in the amount of coal washes, and mineral content increased. These two factors have caused the increase of coal gangue. In 1984, the coal industry in the Soviet Union under the auspices of the Ministry of gravity selected the amount of rock 104 million tons, 8 million tons of flotation waste. The cost of transportation, storage and storage of gangue at coal bases: re-election of waste rock is 0.45-0.55 rubles / tonne, flotation tailings is 1%
