摘　　要：井下运输巷作为煤炭外运的主要通道,其运行安全对矿井综合效益影响显著。而煤尘作为原煤运输中的伴生产物,一直是威胁运输安全的重要因素,采取有效措施,控制巷道内煤尘扩散,降低煤尘危害性意义重大。以此为着手点,针对井下运输自动除尘系统的应用开展探究。结合具体工程实际,对封闭式水膜除尘系统的应用设计开展综合分析,并对其实际应用效果做出检验分析。结果表明,采用封闭式水膜除尘系统的巷道内全尘除尘率与呼吸粉尘除尘率分别达到89%和86%,整体除尘效果良好,同时封闭式水膜除尘系统对巷道正常通风的影响十分小,该系统的应用为井下运输作业的安全进行提供了有力支持。Underground transportation roadways are the main channel for coal transportation,and the safety of its operation has a significant impact on the comprehensive benefits of the mine.Coal dust,as a by-product in the transportation of raw coal,has always been an important factor threatening the safety of transportation.It is of great significance to take effective measures to control the coal dust spread in the roadway and reduce the danger of coal dust.With this as a starting point,the application of the automatic dust removal system for underground transportation was explored.Combined with specific engineering practice,this paper carried out a comprehensive analysis of the application design of the closed water film dust removal system,and tested and analyzed the actual application effect.The results showed that the total dust removal rate and respiratory dust removal rate of the closed water film dust removal system reached 89%and 86%respectively,and the overall dust removal results were good.At the same time,the impact of the closed water film dust removal system on normal ventilation of the roadway was slight.The application of the system provides strong support for the safety of underground transportation operations.
