针对滴道矿立井瓦斯灾害严重的现状,应用灰色系统理论对28#主采煤层进行了瓦斯含量与影响因素的关联分析,建立了瓦斯含量与主要影响因素的GM(1,4)灰色预测模型,并进行了瓦斯含量预测。结果表明:煤层底板标高、灰分和瓦斯成分CH4是影响28#煤层瓦斯含量的主要因素;所建立的灰色预测模型具有良好的精度,能够应用于瓦斯防治工作。 In view of the serious status quo of mine gas disaster in drip mine, gray system theory was used to analyze the relationship between gas content and influencing factors in No. 28 main coal seam, and the GM (1,4) gray forecasting of gas content and main influencing factors was established Model, and carried out gas content prediction. The results show that coal seam floor elevation, ash content and gas composition CH4 are the main factors affecting the gas content of 28 # coal seam. The established gray prediction model has good accuracy and can be applied to gas prevention and control work.
