基于AHP–物元可拓模型的顶板水疏放程度评价

为了科学合理地评价工作面顶板水疏放程度，分析了工作面涌水量预测值和疏放水观测值等要素，构建了顶板水疏放程度评价指标体系，划分了相应的评价等级标准，并利用AHP法确定了各评价指标的权重，建立了顶板水疏放程度的物元可拓模型。利用AHP-物元可拓模型对宁东煤田水文地质条件较为复杂的5个工作面顶板水疏放程度进行了评价，评价结果均为顶板水疏放程度好，并且各工作面已经实现了安全回采，实际情况与评价结果一致。AHP-物元可拓模型可以用于评价顶板水疏放程度，并且可以作为工作面采前水文地质条件评价的参考依据。 

Evaluation on drainage degree in roof based on AHP-matter element extension model

In order to evaluate the drainage degree of roof of working face scientifically, the elements such as the predicted water inflow and the observed drainage value in working face were analyzed, the evaluation index system of water drainage degree in roof was established and corresponding grade standard of evaluation was divided. AHP was used to evaluate the water drainage degree in roof in 5 working faces with relatively complicated hydrogeological conditions. The evaluation results showed that the water drainage in roof was good, and safe extraction has been realized in the working faces, the actual situation was consistent with the evaluation results. AHP-matter element extension model can be used to evaluate water drainage degree in roof, and used as reference basis for evaluation of the hydrogeological conditions in working face before mining.
