煤矸石综合利用的途径很多,如烧沸腾锅炉提供热能;生产煤矸石煤气;从煤矸石中提取有用成分等。但是从目前的水平和经济效益考虑,除部分能源可供充分利用外,大最的煤矸石必须寻找新的利用途径。随着国外建筑业的发展,建筑材料的需要量也与日俱增,利用工业废渣代替天然资源生产建筑材料已成为一 There are many ways for the comprehensive utilization of coal gangue, such as boiling boilers to provide thermal energy; production of coal gangue gas; and extraction of useful components from coal gangue. However, considering the current level and economic benefits, apart from the fact that some energy sources can be fully utilized, the largest coal gangue must find new ways of utilization. With the development of foreign construction industry, the demand for building materials is also increasing day by day. The use of industrial waste residue instead of natural resources to produce building materials has become a
