掘进机可控循环通风除尘方法与措施研究

Study on the method and measures of controllable circulation ventilation and dust control for roadheader

贵州开磷集团采用悬臂式掘进机进行巷道的快速掘进,采用局扇抽出式通风方法辅以高效除尘风机的半循环通风方法,不仅解决了巷道掘进机在非煤矿山快速掘进时产尘量大的问题,而且对未来连续采矿设备的通风防尘具有重要参考意义。

Boom-type roadheader was adopted in Guizhou KaiLin （Group）to carry on roadway rapid excavation. The local fan exhaust ventilation was adopted and assisted by efficient dedusting fan of semi cycle ventilation method. The method not only solved the problem of producing dust in rapid excavation of dintheader of non-coal mine, but also have important reference significance for the ventilation and dust prevention of future consecutive boring equipment.
