在目前煤矿中,井下巷道构成越来越复杂的通风网路连接.如在超级瓦斯矿井和煤与瓦斯突出矿井,都要求井下采掘工作面不能有串联通风,因而造成了复杂的角联通风网路,山区多风机和多井口的通风网路,多水平生产的通风网路等等.用笔算是很难完成整个网路解算工作的,只有使用数字式电子计算机,解算起来才非常方便.矿井的通风系统技术改造,新增加采区,矿井生产的变化,井下救灾工作的通风管理等等.也都需要进行通风系统的调整,而采用电子计算机,均可在很短时间内,通过计算来确定通
In the current coal mines, underground tunnels constitute more and more complex ventilation network connections, such as super-gas mines and coal and gas outburst mines, which require that the underground mining face can not be ventilated in series, thus creating a complex cornering ventilation network Road, mountainous multi-wellhead and multi-well ventilation network, multi-level production of ventilation network, etc. Pen is difficult to complete the entire network solution, and only use the digital computer, solution is very convenient Ventilation system technological transformation of mines, newly added mining areas, changes in mine production, ventilation management in underground disaster relief work, etc. All also need to adjust the ventilation system, and the use of electronic computers can be adopted in a very short period of time Calculation to determine the pass
