矿井通风的任务,就是把大量的新鲜空气送到井下,防止有害气体过多而发生危险事故.所以良好的通风情况,对保证工人的安全生产、身体健康、和不断地提高劳动生产率有着积极的促进作用.随着小煤窑产量的提高和日益向深部发展,对通风的要求也就愈来愈突出,因此改善井下通风已成为当前小煤窑改造工作中迫切的任务之一.通风的方法分自然通风和机械通风两种.
The task of mine ventilation is to send large amounts of fresh air downhole to prevent dangerous accidents caused by excessive amounts of harmful gases, so good ventilation has a positive effect on ensuring workers’ safety in production and their health and continuously improving labor productivity Promote the role.With the increase of the output of small coal mines and the deepening of the development of the increasingly stringent requirements for ventilation, so to improve the underground ventilation has become an urgent task in the transformation of small coal mines nowadays. Ventilation and mechanical ventilation of two.
