解决煤炭工业中燃料-能源的合理利用问题,在很大程度上取决于选煤企业综合处理尾矿的组织工作。由于采煤规模的扩大,所开采矿床的矿山地质条件恶化,采矿技术和工艺的改进,从而增加了需要选别煤炭的数量,提高了其中矿物组分的含量,这两个因素导致了选煤企业尾矿数量的急剧增加。 1984年,苏联煤炭工业部所属企业的煤炭重选尾矿量超过了1.04亿吨,而浮选的尾矿量也超过了800万吨。各产煤区用于运输、堆放、保存尾矿的费用平均为0.45—0.55卢布/吨岩
To solve the problem of rational utilization of fuel and energy in the coal industry depends to a large extent on the organization of tailings disposal by coal preparation enterprises. Due to the enlargement of the coal mining scale, the geological conditions of the mines in the mined deposits are deteriorated, and the improvement of the mining technology and technology, thereby increasing the quantity of coal to be sorted and the content of the mineral components therein. These two factors lead to the coal preparation The number of tailings business increased dramatically. In 1984, the number of coal tailings tailored to the coal industry owned by the Soviet Ministry of Coal Industry exceeded 104 million tons, and the amount of flotation tailings also exceeded 8 million tons. The average cost for transporting, stacking and preserving tailings in each coal producing area is 0.45-0.55 rubles / ton rock
