摘要
新集二矿2401工作面煤体较为坚硬,渗透率低,瓦斯含量高,压力大,不具备保护层开采条件,常规的井下瓦斯治理措施已不再满足相关规定和下一步安全开采需要。基于晋能控股集团寺河矿矿区、沙曲矿的地面井预抽瓦斯效果,分析并论证了新集二矿地面井瓦斯治理的可行性。分析结论认为,2401工作面地面井预抽区域瓦斯治理技术在安全上具有可行性和可靠性。
The coal in 2401 working face of Xinji No.2 Mine is relatively hard,with low permeability,high gas content,high pressure,which has no protective layer mining conditions,and conventional underground gas control measures no longer meet the relevant regulations and the next step of safe mining needs.Based on the pre-draining effect of gas in the surface wells of the Sihe Mine and Shaqu Mine of Jinneng Holding Group,this paper analyzes and demonstrates the feasibility of gas control in the surface wells of Xinji No.2 Mine.The analysis concludes that the gas treatment technology in the pre-drainage area of surface wells in 2401 working face is feasible and reliable in terms of safety.
