摘　　要：贵州省煤矿瓦斯灾害严重,较大、重大瓦斯事故时有发生,随着各煤层开采深度的增加,瓦斯灾害防治任务变得更加艰巨。构建常态化、规范化瓦斯治理长效机制,推进瓦斯灾害治理向事前预防转型,防范煤矿瓦斯事故发生具有重要意义。通过收集毕节市35个构造单元的113个煤层的瓦斯参数,为研究毕节地区瓦斯含量、压力与埋深的关系提供了充足的基础数据。通过对收集的数据运用MATLAB软件进行分析,建立瓦斯含量、压力与埋深一元线性回归数学模型,同时寻找测点中的离群点、高杠杆点、强影响点等不利影响的测点,对一元线性回归数学模型进行回归诊断分析。并在此基础上建立瓦斯大数据库,用于预测未来开采矿区范围内煤层的瓦斯含量和压力,为制定煤层瓦斯抽采措施,防范煤矿瓦斯事故提供依据。Coal mine gas disaster is serious in Guizhou Province,and major gasaccidents are frequent occurrences.With the increase of mining depth,the prevention and control of gas disasters has become more challenging.It is of great significance to build a normalized and standardized long-term mechanism for gas control,advance the transformation of gas disaster control to pre-emptive prevention,and prevent the occurrence of gas accidents in coal mines.Collects the gas parameters of 113 coal seams of 35 tectonic units from Bijie city,which provides sufficient and basic data for studying the relationship of gas content,pressure and buried depth in Bijie area.Through the analysis of the collected data using MATLAB software,the mathematical model of the univariate linear regression of gas content,pressure and buried depth is established.At the same time,the measurement points with adverse effects such as outliers,high leverage points and strong influence points are found,and the regression diagnosis analysis of the univariate linear regression mathematical model is carried out.On this basis,a large gas database is established to predict the gas content and pressure of the coal seams within the mining area in the future,and provide a basis for formulating coal seam gas extraction measures and preventing coal mine gas accidents.
