摘　　要：掘进巷道是井下主要的产尘点之一,在掘进面处粉尘的浓度常常远远高于国家标准,对矿山掘进巷道内粉尘运移规律的相关研究现状进行了分析,系统总结了掘进巷道不同通风方式下(压入式、抽出式和混合式通风)粉尘的运移扩散规律以及通风参数对排尘效果的影响;总结了不同通风方式下粉尘浓度的运移规律,不同通风方式下排尘的最佳通风参数;对未来的掘进巷道内粉尘扩散污染研究提出了展望,以期为矿山粉尘防治工作提供理论和技术支持。Tunneling roadway is one of the main dust producing points in the mine, dust concentration in heading face is always extremely higher than national standards. This paper analyzed the research status of dust movement laws in excavation roadways,systematically summarized the movement and diffusion of dust under different ventilation modes of heading roadway（forced ventilation, exhausted ventilation, combined forced/exhausted ventilation） and the influence of ventilation parameters on dust removal efficiency, summarized the dust concentration movement laws under different ventilation modes and the optimal ventilation parameters under different ventilation modes, and proposed the future research on dust diffusion pollution in tunneling roadway in order to provide theoretical and technical support for mine dust prevention and control.
