摘　　要：以临沂矿区田庄煤矿N2601薄煤层炮采工作面为研究背景,运用Fluent软件,通过气固两相流数值模拟方法对工作面各产尘工序粉尘运移规律进行研究。结果表明:人工攉煤和打眼产生粉尘多数向人行道扩散,而爆破落煤产生粉尘多数随风流沿煤壁运动,少数粉尘向人行道一侧扩散。研究结果可以为现场炮采工作面防尘技术措施提供理论指导。The paper is aimed at introducing the numerical simulations of the gas - solid two - phase flow in the use of fluent software so as to trace the migration regularity of blasting dust under current conditions. The whole study has been done by taking the thin blasting mining face in Tianzhuang Coal Mine in Linyi Mining Area as the research background. The results show that： most of artificial shovel coal and drilling dust diffuse to the sidewalk. And, most of coal blasting spread to the sidewalk. The research results face dust control. dust move along the coal wall along the wind, a can provide theoretical guidance for the blasting handful of dust mining working
