摘　　要：基于某矿综放面采煤机截割煤壁过程中存在煤尘量大、在综放工作面扩散速率较快的问题,对采煤机现有喷雾装置进行优化改进设计,包括在采煤机风口处设计L形喷雾、机身喷雾、破碎机喷雾以及摇臂喷雾装置等,实现对综放工作面从源头上进行高效抑制除尘效果。通过实际应用发现,优化改进后的综放面除尘效率可达68%,工作环境得到大幅改善。Based on the current situation of a mine's coal mining machine cutting coal wall in the process of coal dust,the existing spray device of the coal mining machine was optimized and improved,including the design of L-shaped spray,body spray,crusher spray and rocker spray device at the air outlet of the coal mining machine to achieve efficient dust removal from the source of coal dust in the header.The optimized and improved dust removal efficiency of the face is 68% and the working environment has been significantly improved.
