中文摘要：

对大同原煤进行深度脱灰，考察煤炭中常见的三种难溶性矿物与水煤浆黏度的关系。通过体积浓度校正，进一步探讨了矿物密度对水煤浆黏度的影响。结果表明，难溶性矿物的密度是影响CWS体系黏度的主要因素，同时还需考虑矿物表面的性质。

英文摘要：

The relationship Coal Water Slurry （CWS） between there non- soluble minerals -quarts, pyrite and calcite and the viscosity of was studied with Datong deep - cleaned coal. The influence of the density of minerals on the viscosity of Coal Water Slurry was researched by volume calibration. It is shown that the viscosity of Coal Water Slurry is mainly affected by the density of minerals . While the surface properties of minerals can product impact on CWS.
