摘　　要：针对沙梁煤矿144205工作面截割产尘量大、粉尘扩散并严重污染人员作业区域的问题,根据粉尘产生及运移特点,提出采煤机外喷雾系统+控降尘系统+机载除尘器的综合治理措施;针对回风巷粉尘已均匀扩散、严重影响视线的问题,提出了分段分流净化系统。应用结果表明,采煤机截煤产尘向行人侧的扩散得到了有效控制,工作面和回风巷作业环境得到了明显改善。Aiming at the problems of excessive dust generation,dust dispersion and pollution in personnel operating area resulting from cutting operations at 144205 working face in Shaliang coal mine,arccording to the dust generation and movement characteristic,a comprehensive control measure was proposed,encompassing an external spraying system for shearer+dust reduction system+mounted dust collector.Aiming at the dust being evenly dispersed in the return-air roadway and seriously affecting visibility,proposed a segmented and flow-diverting purification system.The results of the application show that the dispersion of coal cutting dust to the pedestrian side of the coal mining machine has been effectively controlled,and the operating environment of the working face and the return-air roadway was significantly improved.
