异常地质构造对选煤的影响及对策

The effects and countermeasure on coal-preparation to the abnormal geological structure

选煤厂要想获得较好的经济效益必须抓好原煤和精煤质量 .异常地质构造是影响原煤质量的主要因素 ,因此加强回采过程中的煤质管理具有非常重要的意义 .本文介绍潘三矿通过合理布置采场 ,将在异常和正常地质构造时开采的原煤从主井单独提运到地面 ,经选煤厂分别洗选 ,生产出两个质量规格的精煤产品 ,取得了显著的经济效益 .

In order to earn good economical benefits, coal preparation plants must pay attention to the quality of raw_coal and concentration. The abnormal geological structure is the main factor to effect the raw_coal quality. Therefore, it is very important to strengthen the coal quality management in stoping. It has introduced the experience of obtaining remarkalbe benefits through reasonably arranging the stope, separately elevating the coal stoped in the normal and abnormal geological structure to the ground from the main shaft, apartly processing in washery, and producing two_specification concentrating in Pansan coal mine.
