针对目前矿井通风系统存在的问题,并提出了改进措施。随着开采范围不断扩大,深度逐渐增加,供风距离越来越长,通风阻力显著增加,风量不能满足二水平同时生产要求。通过通风状况分析和通风阻力测定,找出影响矿井通风的阻力段进行通风路线调整,同时采取减小矿井漏风等措施,提高了矿井有效风量。 Aiming at the existing problems of mine ventilation system, some measures for improvement are put forward. With the continuous expansion of the mining area, the depth is gradually increasing, the wind distance is longer and longer, the ventilation resistance is significantly increased, and the wind capacity can not meet the requirements of two levels of production at the same time. Through the ventilation status analysis and ventilation resistance measurement, find out the resistance section affecting the ventilation of the mine to adjust the ventilation route, and take measures such as reducing the air leakage of the mine to improve the effective air volume of the mine.
