硫化氢(H2S)是一种剧毒气体,当人吸入浓度1g/m3的硫化氢时,数秒钟内会致人死亡。本文通过分析煤矿瓦斯中硫化氢异常的成因,提出了预防煤矿硫化氢危害的措施。
Hydrogen sulfide (H2S) is a highly toxic gas that can cause death within seconds when inhaled by hydrogen sulfide at a concentration of 1 g / m3. In this paper, by analyzing the causes of hydrogen sulfide abnormalities in coal gas, measures to prevent the harm of hydrogen sulfide in coal mines are put forward.
