矿井可控循环风研究

Study on Controllable Mine Circulating Ventilation

随着矿井开采深度和规模的增加,通风阻力不断加大,矿井的通风越来越困难,为采掘工作面配备足够的风量逐步成为一个挑战性的问题。在低瓦斯矿井,利用可控循环风技术在区域供给风量不变的条件下,能够解决采掘工作面的瓦斯、粉尘、温度和火灾问题,有望成为一个经济、合理、可行的解决方案。

With the increase of mining depth and scale,the ventilation resistance continued to increase,and the mine ventilation became more and more difficult,as a result,to supply sufficient air flow for the winning and opening faces has gradually become a challenging issue.In a low gassy coal mine,the utilization of the controllable circulating ventilation can solve the problems of gas,dust,temperature and fire in the winning and opening faces under the condition of the stable regional air supply,so it may become an economic,rational and workable solution.
