有机煤广泛地用作动力燃料和化工原料。而石煤(灰粉、煤渣、选矿尾矿),目前只是在国民经济的某些部门中得到少量的应用(不超过2%)。这有很多原因:第一,在对煤进行地质勘探工作时,没有对煤的综合利用的可能性作出评价,对非可燃煤的储量尚未计算,因此后者只作为副产原料加以研究。第二,所制定的利用煤灰生产一定物料的工艺流程,目前在工业上尚未得到广泛应用。
Organic coal is widely used as a power fuel and chemical raw materials. Stone coal (ashes, coal cinder, tailing ore) is currently only used in small quantities (up to 2%) in some sectors of the national economy. There are many reasons for this. First, in the geological exploration of coal, the possibility of comprehensive utilization of coal has not been evaluated. The reserves of non-combustible coal have not been calculated yet. Therefore, the latter is only studied as a by-product raw material. Second, the developed process for the production of certain materials using coal ash has not yet been widely applied in industry.
