目前,对煤矸石的综合利用已愈来愈被人们所重视,在型材方面,主要是利用煤矸石制砖、制瓦、生产砌块、板材等;其次是利用煤矸石生产火山灰质普通硅酸盐水泥。由于不断的开拓煤矸石综合利用新途径,近年来,以自燃煤矸石为原料,生产砌筑灰已逐年增多,利用范围也在逐步扩大。仅就双鸭山矿务局为例:利用自燃煤矸石生产砌筑灰已有十余年历史,产品产量逐年上升,到1985年,生产能力已达3000余吨。利用范围、熟练程度越来越好。另外,鸡西、鹤岗等矿务局每年都生产相当数量的这类产 At present, the comprehensive utilization of coal gangue has been paid more and more attention by people. In the aspect of profile, the main use of coal gangue is to make bricks, tile, block, plate, etc.; secondly, it uses gangue to produce pozzolanic ordinary silicic acid. Salt cement. Due to continuous development of new methods for the comprehensive utilization of coal gangue, in recent years, self-burning coal gangue as raw materials, the production of masonry ash has increased year by year, the scope of use is gradually expanding. Take the Shuangyashan Mining Bureau as an example: It has been more than ten years since the self-burning coal gangue was used to produce masonry ash. Product output has increased year by year. By 1985, the production capacity has reached more than 3,000 tons. The scope of use and proficiency are getting better. In addition, Jixi, Hegang and other mining bureaus produce a considerable amount of these products each year.
