一、煤矸石概况蒲白矿区煤矸石是与煤层共生宝贵的有用矿物。但因从矿井每年运出地面大量煤矸石还不能及时加工利用,大部排放到深沟之中,就成了工业废碴,煤矸石洗矸综合利用,就能逐步变废为宝,节约能源,少占农田,改善环境,减少无效运输,明显增加经济效 First, the overview of coal gangue Pu Bai mining gangue is a valuable symbiotic coal and useful minerals. However, due to a large number of gangue from the mine every year out of the ground can not be processed in time, most of the emissions into the deep groove, it has become an industrial waste ballast, gangue gangue comprehensive utilization, we can gradually turning waste into treasure, energy conservation , Accounting for less farmland, improving the environment, reducing ineffective transportation and obviously increasing economic efficiency
