提出了一种新型的钻孔布管抽采方案,对机械封孔特性进行了分析,同时提出了对井下通风系统的优化方案,利用微机控制及变频控制技术,实现了矿井通风系统根据井下瓦斯含量灵活调整通风特性,既满足了通风安全性的需求,显著地降低了在通风作业过程中的能源消耗,根据实际应用表明采用钻孔布管抽采方案和新的通风系统能够有效地降低井下发生瓦斯突出事故的概率,提升综采作业的安全性。

This paper puts forward a new type of drilling and pipe laying drainage scheme,analyzes the mechanical hole sealing characteristics,and puts forward the optimization scheme for the underground ventilation system.By using the microcomputer control and frequency conversion control technology,the mine ventilation system can flexibly adjust the ventilation characteristics according to the underground gas content,which not only meets the requirements of ventilation safety,but also significantly reduces the ventilation operation.According to the practical application,it is shown that the new ventilation system and the drilling pipe layout can effectively reduce the probability of gas outburst accidents and improve the safety of comprehensive mining operation.
