| 摘 要： | 为提高煤与瓦斯突出矿井瓦斯抽放效果,建立了3个一级指标、14个二级指标的突出矿井瓦斯抽放限制影响因素评价指标体系,利用AHP和熵权法分别确定指标因子主、客观权重.通过实地调研分析和反馈验证了AHP-熵权法的可行性和正确性,利用加权平均法确定评价模型的综合权重.研究表明:封孔方式、钻孔半径、抽放时间、煤体裂隙发育程度和抽放负压是目前影响煤矿瓦斯抽放效果的主控因素.

| Abstract: | In order to improve the effect of gas drainage in coal and gas outburst mines,three first-level indicators and 14 second-level indicators have been established to evaluate the influencing factors of gas drainage restrictions in outburst mines.AHP and entropy weight methods are used to determine the main and objective weight.Through field investigation analysis and feedback verify the feasibility and correctness of the AHP and entropy method,sing the weighted average method to determine the comprehensive weight of the evaluation model.The research shows that the sealing method,drilling radius,pumping time,coal seam development degree and pumping negative pressure are the main controlling factors affecting the gas drainage effect of coal mines. |
