摘要
为提高矿井煤层润湿性评价的准确性,运用层次分析法确定煤层润湿性各影响因素权重系数,采用模糊综合评判法建立煤层润湿性评价模型。针对木瓜煤矿煤层润湿性的模糊综合评价结果为2.61,属于难润湿等级,该结果与实验测定接触角分级结果相一致,说明基于AHP-模糊综合评判建立的煤层润湿性评价模型可以满足煤层润湿等级预测的需要。
To improve the accuracy of coal seam wettability in coal mine, an evaluation model of coal seam wettability was established by using fuzzy comprehensive evaluation, in which the impact assessment weights were determined by using analytical hierarchy process（AHP）. The result showed that coal seam wettability result of Mugua Coal Mine is 2.61, and this coal seam belongs to difficult wetting grade, which has the same conclusion with the measurement result by experimental apparatus. The evaluation model which based on AHP-fuzzy comprehensive evaluation can meet the need of prediction for the grade of coal seam wettability.
