摘要
地面大气压力的下降多引起瓦斯事故,通过新疆阜康西沟煤矿一年的气候观测数据,统计分析了该矿井瓦斯涌出(体积分数)的四季分布情况,确定了瓦斯事故"危险期",这对矿井日常瓦斯管理具有一定的指导意义,也为该矿制定预防瓦斯事故的安全措施提供了可靠的依据。
Gas explosion accident is more likely caused by the drawdown of atmospheric pressure on the ground. According to the one- year climate- observation data of Fukang, Xigou Coal Mine in Xinjiang, distribution of gas outburst （concentration） in four seasons is analyzed, and. the ＂critical stage＂ of gas explosion accident is determined, which have certain meaning of guidance for the routine management of gas in coal mine and provide reliable foundation for enacting safety regulations to prevent gas explosion accident.
