30Mt／a斜沟煤矿选煤厂设计分析

Design Analysis on 30 Mt/a Xiegou Coal Mine Preparation Plant

对30 Mt/a斜沟煤矿选煤厂的煤质情况进行了分析,并根据煤质情况,进行了产品定位。介绍了产品销售情况,对后期入洗方式进行了探讨,确定了合理定灰点;论述了该厂的主洗系统,厂房结构的选定,产品装车系统以及施工原则。针对斜沟煤矿选煤厂是一个特大型矿井型选煤厂,指出在设计中应兼顾到炼焦配煤和动力煤两种产品的合理配比,以确保该厂经济效益的最大化。

Analyses the coal property situation of 30 Mt/a Xiegou coal preparation plant, according to coal prop- erty situation and makes the product positioning. Introduces the product sale situation, discusses the washing mode in later stage, determines a reasonable setting ash point, also elaborates the main wash system of the plant, the selection of the workshop structure, product loading system and construction principles. In view of the Xiegou coal preparation plant as a large coal mine preparation plant, points out in the design should take into account reasonable proportioning of the two products of coking coal blending and thermal coal and ensures the maximization of economic benefits in the plant.
