With the high-intensity development of coal resources and the rapid development of coal chemical industry, a large number of low-quality coal and coal measure solid wastes have been produced, such as inferior coal, slime, coal fly ash and coal gasification slag. Coal processing and quality improvement technology is an important link to realize the recycling, high-value, clean and efficient utilization of low-quality coal. Based on the actual problems faced in the current coal separation and utilization process, introduces the engineering practice and technical achievements carried out by Shandong Energy Group in the fields of final coal dry separation, comprehensive utilization of coal slime and solid waste recycling in recent years, The dry separation equipment of final coal developed by our team effectively solves the problem of efficient ash reduction of −6 mm granular coal, and The low temperature drying technology of coal slime can improve the quality of low quality coal slime at low cost, and The new wet briquette technology has effectively solved the pollution problem of loose burning coal. The technology research of coal-based solid waste resource preparation of high-strength ceramide and coal gasification ash preparation of mine filling material carried out by the company aims to explore the utilization way of coal measure solid waste based on decrement disposal and supplemented by high value conversion.
