摘要
Abstract
This article uses numerical simulation methods to study the dust diffusion characteristics during continuous dust productior periods,with the aim of analyzing the dust distribution and migration behavior around the driver of the tunneling machine,in order to determine effective underground coal mine dust control measures.The simulation results indicate that during the continuous dust productior process,the dust concentration continuously increases and gradually reaches a stable level.During this process,the driver's position is always at the intersection of the original migrating dust and the returning dust,and the driver is invaded by these two streams of dust.The article designs a dust separation and extraction system,including vacuum pumping and air curtain devices,aimed at controlling the dust around the roadheader driver.The system was applied on site,and the results indicate that the dust removal system can effectively reduce the dust concentration around the roadheader driver,with a dust removal rate of 92.7%.关键词
