一、序言目前对煤矿中通风方面的问题,都是通过用计算的方法解决的,计算的方法主要的是用与解电的网路相似的方法,来解通风网路,最后得出各部份的风量与负压,计算的方法最大的缺点是计算过程复杂,同时计算的方法并不能解决全部通风上的问题,譬如各巷道风流的方向有时用计算的方法就不能确定,对于通风系统简单的矿井,计算的方法尚可利用,对于一些通风系统比较复杂的旧矿井,计算的方法就不一定能解决全部的问题,甚至在某些场合
I. Preface At present, the problems of ventilation in coal mines are solved by means of calculation. The main method of calculation is to use the method similar to that of the power-off network to solve the ventilation network and finally obtain the ministries Part of the air volume and negative pressure, the biggest drawback is that the calculation method is complex, while the calculation method does not solve all the problems on the ventilation, such as the direction of the roadway flow sometimes calculated by the method can not be determined for the ventilation system is simple Of the mine, the calculation method is still available, for some of the more complex ventilation system of the old mine, the calculation method may not be able to solve all the problems, and even in some occasions
