摘要
中国煤矿井下开采过程中,不可避免地受到煤层中释放瓦斯的影响。为了实现煤矿的安全开采,必须采取合理的措施对瓦斯进行防治,其中,矿井通风是瓦斯防治的基本手段。分析了煤矿矿井瓦斯防治技术,主要是实施矿井通风,使得巷道风流中瓦斯体积分数维持在一个较低的水平,从而避免瓦斯事故的发生,重点探讨了改善矿井通风瓦斯防治效果的技术措施,主要包括进行风量的合理分配、减少巷道的漏风、做好上隅角处的通风和进行通风网络优化,可以为煤矿瓦斯防治提供一定的参考。
In the process of underground coal mining in China,it is inevitably affected by the gas released in the coal seam.In order to realize the safe mining of coal mines,reasonable measures must be taken to prevent and control gas,among which,mine ventilation is the basic means of gas prevention and control.This paper analyzed the gas prevention and control technology in coal mines,mainly implementing mine ventilation to maintain the gas volume fraction in the air flow of the roadway at a low level,so as to avoid the occurrence of gas accidents,and focused on the technical measures to improve the gas prevention and control effect of mine ventilation,mainly including the reasonable distribution of air volume,reducing the air leakage of the roadway,doing a good job in the ventilation of the upper corner and optimizing the ventilation network,which can provide some reference for coal mine gas prevention and control.
