摘　　要：煤矸石是一种固体废弃物,长期堆放会发生自燃,释放有害气体,不仅造成大气污染,而且落地后煤矸石中有害元素会经雨水淋溶进入水域或渗入土壤,影响水体和土壤的质量,粉煤灰就地堆放,占用大片土地,见风飞扬等特点,不仅浪费能源,污染环境,而且严重影响职工及当地居民的健康,利用煤矸石、电厂粉煤灰生产环保砖,既减少粉煤灰和煤矸石占地面积对环境的影响,又增加经济效益,使矿区环境根本上得以改善,但制砖仅处于价值链的最低端,陕能股份走产学研结合道路,注重基础理论研究,加强对煤矸石、粉煤灰成分定性定量分析,争取在“十四五”至“十五五”期间实现永陇矿区麟游园子沟煤矿煤矸石、麟北电厂粉煤灰生产高附加值产品,推动企业转型升级。Coal gangue is a kind of solid waste.Long term stacking of coal gangue will cause spontaneous combustion,release harmful gases and cause air pollution.The harmful elements in coal gangue will be leached into water or soil by rainwater,affecting the quality of water and soil.Fly ash is piled up on the spot and occupies a large area of land,which not only wastes energy and pollutes the environment,but also seriously affects the health of workers and local residents.Using coal gangue and power plant fly ash to produce environmental protection brick can not only reduce the impact of fly ash and coal gangue on the environment,but also increase the economic benefits,so that the environment of mining area can be fundamentally improved.However,brick making is at the lowest end of the value chain,so it is necessary to pay attention to basic theoretical research,strengthen qualitative and quantitative analysis of coal gangue and fly ash composition,strive to realize the production of high value-added products from coal gangue of Linyou Yuanzigou coal mine and fly ash of Linbei power plant in Yonglong mining area during the period from the 14th five year plan to the 15th five year plan period,so as to promote the transformation and upgrading of enterprises.
