井下煤尘产生机理分析

煤尘严重污染井下空气,特别是呼吸性粉尘,严重危害工人身体健康。而且高浓度的煤尘遇到点火源还有爆炸危险,造成重大伤亡事故,是威胁井下安全生产的主要灾害之一。煤矿井下作业大部分都会产生煤尘,采掘工作面和转载点会造成大量的煤尘飞扬,导致煤尘浓度增大,是井下煤尘的主要来源。分析了采掘工作面和转载点处煤尘产生的机理,指出煤尘产生的主要来源和影响因素,提出减少煤尘的技术措施,为设计高效除尘工艺提供理论依据。

Analysis of the Coal Dust Mechanism of Separating out

The coal dust is not only cause serious air pollution,especially the respirable dust are harmful to the health of workers.And high concentrations of the coal dust are easy to explosion when met the ignition source,causing heavy casualties,is one of the main disasters in coal mine.The coal dust exist in all most production process,in particular,the working face and transport site cause high heavy dust is the main source of the coal dust.This paper analyzes the working face and transport site coal dust mechan...
