| description | The invention discloses a coal seam roof or floor aquifer water-rich property comprehensive evaluation method. The method adopts an equivalent aquifer thickness M, unified aperture unit water inflow q, a research area structure capacity dimension D and a roof or floor aquifer conductivity value delta as discrimination indexes, and utilizes an analytic hierarchy process and an entropy weight method(AHP-EMM) to comprehensively calculate the weight of each evaluation index. And the obtained comprehensive index weight and the normalized index data are substituted into a formula to calculate a water-rich property index, and a water-rich property partition map is drawn by using drawing software. The indexes used for evaluation are clear in physical significance, simple to operate, easy in dataacquisition and easy in practical application.
本发明公开了一种煤层顶板或底板含水层富水性综合评价方法，采用等价含水层厚度M、统一口径单位涌水量q、研究区构造容量维D和顶板或底板含水层电导率值δ作为判别指标，利用层次分析法和熵权法(AHP-EMM)综合计算各评价指标权重，将获得的综合指标权重和归一化后的指标数据，代入公式计算富水性指数，使用绘图软件绘制富水性分区图。本发明评价使用的指标物理意义明确，操作 |
