矿井瓦斯治理及通风系统的优化

Optimization of Mine Gas Control and Ventilation System

为进一步保证煤矿生产的安全性,解决工作面推进所导致的通风能力不足、瓦斯浓度超标的问题,在对B矿生产条件综合分析的基础上,首先,对B矿通风系统现状进行分析总结,提出相应的优化改造方案;其次,在埋管抽放的基础上增加高位钻孔抽放方案,并完成高位钻孔抽放工艺参数的设计;最后,分别对通风系统和瓦斯抽放治理的优化效果进行评估。

In order to further ensure the safety of coal mine production and solve the problems of insufficient ventilation capacity and excessive gas concentration caused by the advancement of working face, based on the comprehensive analysis of the production conditions of mine B, firstly, the current situation of ventilation system of mine B is analyzed and summarized, and the corresponding optimization and transformation scheme is put forward. Secondly, the scheme of high-level borehole pumping is added on the basis of buried pipe pumping,and the design of high-level borehole pumping process parameters is completed. Finally, the optimization effects of ventilation system and gas drainage treatment are evaluated respectively.
