摘　　要：煤矿瓦斯涌出受许多偶然和系统因素影响,瓦斯异常涌出现象难免,采用解析的数学方法难以预测和分析。文章采用统计分析方法分析了大宁煤矿南大巷掘进工作面日最大瓦斯浓度监测值分布规律,结果表明正常情况下,该矿日最大瓦斯浓度值近似服从正态分布,其最大值的平均值为μ=0.349%,标准差σ=0.199。当日最大瓦斯浓度C>0.954%,即为瓦斯异常涌出。若连续时间较长时应查明系统原因,及时采取瓦斯治理补救措施。该研究方法和分析结论可供其他煤矿企业参考。It is difficult to forecast and analyze the gas abnormal emission which is hard to avoid with analytic mathematical method,because gas emission is affected by many accidental and systematic factors.The regularity of distribution of daily maximum gas concentration at south channel driving face Daning coal mine is research using statistical analysis technique.Results showthat daily maximum gas concentration C of mine is normal distribution.The mean of maximum μ=0.349%,and standard deviation σ=0.199.When daily maximum C0.946%,gas abnormal emission may take place.If it continues for long time,systematic reason must be found out,and the measures must be taken.to control gas emission.Other coal mine may consult this research method and analyzing conclusion.
