马泰壕矿选煤厂干选扩能提质可行性分析

Analysis on feasibility of realizing expansion of capacity of dry cleaning system for upgrading of small coal at Mataihao Mine Coal Preparation Plant

为有效解决马泰壕矿选煤厂末煤质量波动问题,实现选煤厂的扩能提质,结合干法选煤发展现状,在原煤煤质特性分析的基础上,对选煤厂扩能提质改造方案进行了探索。分析结果表明:采用干法选煤工艺进行改造是可行的,并可为类似煤炭加工方案选择提供参考。

For effectively tackling the problem regarding the fluctuation of quality of small coal product,and realizing expansion of production capacity,a general survey is made of the current state of development of dry cleaning method.Based on the result of the survey and in line with the property of the raw coal treated,the dry cleaning system is applied for the expansion of small coal treating capacity and improvement of product quality.Practice shows the renovation scheme of using dry cleaning process is practically feasible.The scheme may serve as a reference for other plants for carrying out similar improvement project.
