太原选煤厂原煤配选方案探讨

Research on scheme of raw coal blending separation in Taiyuan coal preparation plant

针对太原选煤厂入选原煤品种多、性质差异大的问题,对西铭矿原煤和杜儿坪矿原煤的配选方案进行研究。根据原煤煤质指标,提出单一矿井原煤配选和两矿原煤相互配选两种方案。原煤配选后可选性得到改善,精煤产品质量稳定性增加,实现了煤炭资源的综合利用。

For the problem of the raw coal varieties and with different properties in Taiyuan coal prepara- tion, investigated the blending separation scheme for raw coal from Ximing coal mine and Duerping coal mine. According to the coal quality index, put forward the two schemes that one is blinding raw coal from single coal mine, and other is from two coal mines. After raw coal blending separation, it improved the washability and increased the stability of clean coal product. It realized the comprehensive utilization of coal resources.
