大采高综采工作面粉尘分布特征研究

Study on dust distribution characteristics of fully mechanized mining face with large mining height

粉尘分布一直是煤矿开采时的难点之一,从大采高综采工艺发展现状以及大采高综采工作面主要产尘源、产尘机理和粉尘质量浓度分布特征以及粉尘分散度分布特征、除尘措施六个方面来进行分析,以此来总结出大采高综采工作面的粉尘分布特征。

Dust distribution has always been one of the difficult points in coal mining.This paper analyzed the development status of fully-mechanized mining technology with large mining height,main dust source,mechanism of dust production,dust mass concentration distribution characteristics and dust distribution characteristics,and dust removal measures of fully-mechanized mining face with large mining height are analyzed to summarize the dust distribution characteristics of fully mechanized mining face with large mining height.
