随着我国煤矿开采技术的不断提升,煤矿开采深度逐渐增加,局部瓦斯浓度过高矿段比例增加,尤其在高瓦斯矿井中更为明显,矿井中瓦斯浓度过高极易引发爆炸,形成巨大安全隐患,影响矿井生产和操作人员生命安全,导致经济效益损失。而高瓦斯矿井通风技术能够有效降低矿井内瓦斯气体浓度,减小安全事故发生几率,高质量的矿井通风能够消除矿井内瓦斯富集段,保障采掘的安全性。本文首先阐述了高瓦斯矿井通风的必要性及瓦斯爆炸的预防,然后对现阶段常用通风技术进行研究,最后分析了高瓦斯矿井有效通风的经济性价值。
With the continuous improvement of coal mining technology in China, the depth of coal mining gradually increases and the proportion of partial high gas concentration increases, especially in high-gas mines. Excessive methane concentration in coal mines can easily lead to explosion, resulting in huge safety Hidden risks affect the lives and safety of miners and operators, resulting in loss of economic benefits. The high-gas mine ventilation technology can effectively reduce the concentration of gas in the mine and reduce the risk of accidents. High-quality mine ventilation can eliminate the gas-rich section in the mine and ensure the safety of mining. This paper firstly elaborates the necessity of ventilation in high-gas mines and the prevention of gas explosion. Then, the common ventilation technology at the present stage is studied. Finally, the economic value of efficient ventilation in high-gas mines is analyzed.
