摘要
针对长距离独头掘进通风难题,通过对单台大功率通风机局部通风、局部通风机串联通风、局部通风机并联通风,全风压与局部通风联合布置,风库局部通风、钻孔通风等局部通风的特点分析比较,为超长距离掘进合理选择局部通风方式提供了依据。
According to the problem of long distance blind heading ventilation, the characteristics of some local ventilation modes, such as local ventilation of single high power local fan, series ventilation of local fan, parallel ventilation of local fan, joint ventilation of full negative pressure ventilation and local ventilation, and borehole ventilation were compared. The research can provide basis for the reasonable selection of ventilation mode in ultra long distance heading.
