1、绪论矿井通风网路内大气的状态,往往与干扰有关,它具有机遇性质。干扰可由以下诸因素引起:瓦斯涌出、瓦斯爆炸、井下火灾、矿车和竖井运输、偶然打开和关闭风门等等,生产过程中网路结构发生变化,同样也对井下大气状态有影响。研究院几年来在这方面进行的工作,就是要制定一个能控制通风网路的自动系统,它可以随时根据有害气体含量的变化和井巷
1. INTRODUCTION The state of the atmosphere in the mine ventilation network is often related to interference. It has the nature of opportunity. Interferences can be caused by gas emission, gas explosion, downhole fire, car and shaft transport, accidental opening and closing of the damper, etc. Changes in the network structure during production also have an effect on the downhole atmospheric conditions. The work the institute has done in this area over the years is to develop an automatic system that controls the ventilation network, which can be readily adapted to changes in the content of harmful gases,
