Abstract: For the problem of the raw coal varieties and with different properties in Taiyuan coal preparation,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.
