摘　　要：为准确、快速预测煤层群煤层瓦斯赋存情况并确定其控制因素,以山西某矿煤层群为背景,通过测试2^(#)、3^(#)煤层瓦斯基础参数,进一步通过线性回归分析,确定各煤层瓦斯赋存规律的主要影响因素。研究结果表明:2^(#)煤层瓦斯含量5.45~6.91 m^(3)/t,3^(#)煤层瓦斯含量7.00~7.11 m^(3)/t,影响因素存在较大差异,前者主要受埋深和煤层厚度影响,后者主要受埋深和煤灰分影响。预期研究结果可为现场工作面瓦斯抽放方案制定,及下组煤瓦斯浓度预测提供基础资料。In order to accurately and quickly predict the occurrence of gas in coal seams and determine its control factors,takes a coal seam group in a certain mine in Shanxi as the background,tests the basic parameters of gas in coal seams No.2 and No.3,and further determines the main influencing factors of gas occurrence in each coal seam through linear regression analysis.The research results show that the gas content in the No.2 coal seam is 5.45-6.91 m^(3)/t,and the gas content in the No.3 coal seam is 7.00-7.11 m^(3)/t,with significant differences in influencing factors.The former is mainly affected by burial depth and coal seam thickness,while the latter is mainly affected by burial depth and coal ash content.The expected research results can provide basic data for the formulation of on-site gas drainage plans and the prediction of gas concentration in the next group of coal.
