摘要
对某煤矿采掘工作面过废弃油气井有毒有害气体中毒窒息事故进行了风险分析。得出了废弃油气井内有毒有害气体主要有硫化氢、甲烷、一氧化碳等气体。采用层次分析法和模糊综合评价法相结合的风险评价法对有毒有害气体中毒窒息事故进行风险评价,得出了开采临近废弃油气井煤层易于发生中毒窒息事故的结果。提出了预防有毒有害气体中毒窒息事故建议,以保证工作面的安全生产。
A risk analysis was carried out on the poisonousand suffocation accidents of toxic and harmful gases in abandoned oil and gas wells in a coal mining face.It is concluded that the toxic and harmful gases in the abandoned oil and gas wells are mainly made of hydrogen sulfide,methane and carbon dioxide.The risk assessment method combining analytic hierarchy process and fuzzy comprehensive evaluation method is used to evaluate the risk of poisonous and toxic asphyxiation accidents,and the results of mining poisonous suffocation accidents near the abandoned oil and gas wells are obtained.Proposed prevention of toxic and harmful gas poisoning asphyxiation accidents to ensure safe production of the working face.
