摘　　要：对开滦林西矿业有限公司选煤厂煤泥水沉降特性进行了研究,优选了絮凝剂和凝聚剂,通过药剂制度的选择和加药方式的改进,以及增加耙式浓缩机水面漂浮物的分离处理设施,有效地解决了林西矿细粒煤泥和8号煤层中赋存的超细矿泥造成的油状絮团物对循环水的聚集污染,从而确保了生产用水质量。the paper analyzed the situation of settling of coal slurry in coal preparation plant of Linxi min- ing company of Kailuan group Co. , Ltd. Take the measures of optimization selectig the flocculant and co- agulant, choosing the regime of agent, improving the agent adding method as well as separating and treating the floater floated on the water surface of rake thickener, which effectively solved the problem of circulating water pollution caused by the oily flocculate that existed in fine slime Linxin coal preparation plant and ul- trafine particle in No. 8 coal seam in Linxi colliery, so ensured the quality of production water.
