近十年来,苏联选煤厂的选后矸石量约增加了2.7倍,现每年已达100万吨。未来选后矸石量的增加趋势还不会改变。收集,运输和存放这类矸石不但花费大(每年超过5千万卢布),而且给环境带来严重的污染。选煤厂矸石比露天矿和矿井矸石的成份和性质较稳定,可用于生产多种建筑材料(建筑陶瓷、人工多孔充填料、排水陶瓷管和粘结材料)。为确定利用各种选后矸石的合理方向,苏联可燃矿物研究所制定了选后矸石分类
In the past ten years, the amount of waste rock after the election of the Soviet Union coal preparation plant has increased by about 2.7 times, now reaching 1 million tons each year. Future increase in the amount of gangue will not change the trend. Collecting, transporting and storing such waste rock not only cost a lot (more than 50 million rubles a year), but also cause serious environmental pollution. Coal preparation plant gangue than opencast and mine gangue composition and properties of more stable, can be used for the production of a variety of building materials (architectural ceramics, artificial porous filler, drain ceramic tubes and bonding materials). In order to determine the rational use of various post-election gangue, the Soviet Union Institute of combustible minerals developed after the gangue classification
