基于可拓学的物元理论和熵原理，构建了煤体注水难易性评价的可拓物元模型，引入熵权法确定煤体注水难易性的权系数。选取裂隙发育程度、孔隙率、煤体湿润边角、煤的硬度和饱和水分增值五个指标作为评判因子，并确定煤体注水难易性分级标准和指标阀值范围，即构建了经典域物元和节域物元。利用建立的模型对五个工程实例进行综合评价，应用研究结果表明：评判结果与工程实际情况吻合良好。因此，可拓学评价方法应用于煤体注水难易性评价是可行的，与传统评价方法相比，具有计算简单、便捷实用，易于在同类工程中推广应用。

Based on the matter-element theory and entropy theory of extenics,a model of extensible matter-element model for evaluating difficulty of water infusion for coal seam was established. In order to determine the weight rati-os on difficulty of water infusion for coal seam,the method of entropy weight was adopted. Five major index factors such as cranny viability,porosity,wet rim angle,hardness of coal,and saturation moisture increment were regar-ded as the discriminant factors. The grading standard and index threshold range on difficulty of water infusion for coal seam were established,namely establishing classical field matter elements and extensional matter elements. The proposed model was applied in five actual water infusion cases. The results fitted well with the actual situation. Therefore,the extenics method is feasible for difficulty assessment of water infusion for coal seam. It is simple, convenient and practical by comparing with the traditional method,and can be applied in similar engineering.
