煤矸石随煤炭生产而产生。日积月累,在矿区形成矸石山,既侵占良田。又污染环境。近年来,一些地区已有利用煤矸石制作建筑材料和提取有用物质,但用量有限。因此,进一步研究利用煤矸石,使大量煤矸石变废为宝,有十分重要的意义。煤炭科学研究总院西安分院对澄合、韩城矿区煤矸石进行了调查、采样,分析了矸石的岩石类型、矿物成分、化学成分、研制了矸石肥料,测试了矸肥 Gangue is produced with coal production. Over time, in the mining area to form gangue hill, both occupy fertile land. Pollution of the environment. In recent years, coal gangue has been used in some areas to make building materials and to extract useful materials, but the dosage is limited. Therefore, the further study of the use of coal gangue, a large number of gangue waste into treasure, there is a very important significance. Xi’an Branch of Coal Science Research Institute conducted a survey on coal gangue in Chengchuang and Hancheng Mining Areas, sampled and analyzed rock types, mineral components and chemical compositions of gangue, developed waste rock fertilizer, tested gangue fertilizer
