摘　　要：为实现矿井瓦斯分级管理,解决煤矿实测瓦斯含量数据少的问题,基于棋盘井煤矿(东区)16号煤层运用灰色关联分析法,分析确定影响瓦斯含量的主控因素,并采用多源瓦斯数据分析构建了反演瓦斯含量模型,进行瓦斯含量预测。研究结果表明,棋盘井煤矿(东区)煤层不同地质单元影响瓦斯赋存的主控因素存在一定差异,基于灰色关联法分析可知,标高是影响地质单元最重要的因素。利用工作面瓦斯涌出量与地勘瓦斯含量反演煤层的瓦斯含量,构建瓦斯对比反演模型,并对划分地质单元进行瓦斯含量预测,预测结果为16号煤层瓦斯含量总体上呈现出“北部比南部多,东部比西部多”的特点,经验证预测模型能够准确反映煤层瓦斯含量。In order to achieve gas classification management in mines and solve the problem of insufficient measured gas content data in coal mines,the grey correlation analysis method was used to analyze and determine the main controlling factors affecting gas content in the No.16 coal seam of Qipanjing Coal Mine(eastern area).A multi-source gas data analysis was used to construct an inverse gas content model,and finally,gas content prediction was carried out.The results indicate that there are differences in the main controlling factors affecting gas occurrence among different geological units in the eastern coal seam of Qipanjing Coal Mine(eastern area).Based on grey correlation analysis method,it can be concluded that elevation is the most important influencing factor for geological unit.By using the gas emission from the working face and the geological exploration gas content to invert the gas content of the coal seam,a gas comparison inversion model was established,and the gas content was predicted for the division of geological units.The gas content of the No.16 coal seam in Qipanjing Coal Mine(eastern area)generally shows the characteristic of“more in the north than in the south and more in the east than in the west”,and the prediction model can accurately reflect the gas content of the coal seam.
