我国煤炭行业的发展受到煤炭开采安全性的制约,因为矿区的地质结构相对复杂,这也给煤炭的开采造成了很大的困难,在开采的过程中还容易造成一定的人员伤亡。其中最主要的原因是矿井的通风不畅造成的,人们在矿井进行开采过程中容易发生呼吸困难甚至窒息的情况这也是造成煤炭开采的安全性下降的主要因素。所以,对煤炭矿井内通风阻力和通风动力的研究十分的重要。 The development of China’s coal industry is constrained by the safety of coal mining because the geological structure of the mining area is relatively complicated. This has also caused great difficulties in the mining of coal and easily causes some casualties in the process of mining. The most important reason is the poor ventilation of the mine, which makes it easy for people to breathe or even suffocate during the process of mining. This is also the main factor that causes the safety of coal mining. Therefore, the study of ventilation resistance and ventilation power in coal mines is very important.
