瓦斯综合治理“一面一策”标准研究--西山煤电矿井回采工作面瓦斯分级治理标准

摘要

为得到回采工作面瓦斯治理的规范性、标准性方案，以西山煤电集团回采工作面的瓦斯抽采方案为例，根据瓦斯来源将回采工作面瓦斯抽采方法归纳为本煤层、裂隙带、下邻近层及采空区4类，将这4类抽采方法和工作面瓦斯绝对涌出量组成复合指标体系，采用系统聚类分析法，并借助SPSS数据处理软件对这些指标进行分析，根据聚类分析结果把回采工作面瓦斯治理划分为4个等级，并提出了不同等级工作面瓦斯治理的基本方法。该划分方法能提高制定瓦斯抽采方案的效率，对相似地质条件矿井的瓦斯治理工作具有指导意义。%For the standardization of the coal face gas management ,put xishan coal electricity group mine working face gas extraction scheme as an example for sorting .According to the gas source ,extraction methods will be summarized as the coal working face ,fissure zone ,adjacent lay_er and goaf .Then put the four types of extraction method and the working face of absolute gas e_mission quantity as an composite index system ,use the method of system clustering ,and with the aid of SPSS data processing software ,got the result of clustering analysis of the working face gas control is divided into four grades ,and put forward the basic methods of different grade working face gas control .The dividing method can improve the efficiency of gas extraction scheme ,and to similar geological conditions of coal mine gas control work as a guiding significance .
