摘要
针对掘进局部通风中大角度转弯巷道存在通风阻力大,漏风大的问题,提出了用负压风筒解决掘进巷道大角度转弯巷道中局部通风存在的问题,成功应用在实际工作中,并在掘进工作面推广应用。
According to the fact that the large ventilating resistance and large air leakage problems existed in the local ventilation in the driftage of large turning angle road, proposes the solution of the problems by the negative pressure fan drum. It＇s successfully used in practice, and has widely spreaded in the heading face.
