【摘要】 研究采煤机在割煤落煤过程中,粉尘在综采工作面的沿程分布情况。利用计算流体力学(CFD)软件,结合某煤矿1207工作面的具体特点和实测数据,分别模拟了采煤机在顺风割煤和逆风割煤2种不同工作条件下,工作面的全尘粉尘和呼吸性粉尘在巷道的可视化分布规律。更多还原

【Abstract】 On-way distribution of dust in the full face mining was researched during the process of coal mining machine cutting coal. Visual regularities of distribution of whole dust and respirable dust of workface were simulated respectively in two different conditions the cutting coal with favorable wind and unfavorable wind,using the software of computational fluid dynamics combined with idiographic characteristic and testing data of 1207 workface for certain coal mine.更多还原
