针对新疆某矿区首采区2煤顶板直接充水含水层组富水性评价问题,提出了基于AHP和Arc GIS的多源地学信息融合评价方法。建立了砂岩累计厚度、泥岩比、断层、钻孔冲洗液消耗量、岩心采取率5个影响直接充水含水层富水性的评价指标体系,基于AHP法确定各影响因素权重,建立了富水性指数模型,提出相对弱富水区、相对中等富水区、相对强富水区分区方案。采用现场抽水试验结果对定性的且相对的评价结果进行了校正。
Aiming at the problem of water-rich evaluation of 2-F coal-bearing direct water-filled aquifer in the first mining area of a mining area in Xinjiang, a multi-source geo-information fusion evaluation method based on AHP and Arc GIS is proposed. The evaluation index system of the water-filled aquifer directly affected by the accumulated thickness of sandstone, mudstone ratio, fault, the consumption of drilling fluid and the rate of core flushing was established. The weight of each influencing factor was determined based on the AHP method, and the water-rich index Model, a relatively weak water-rich area, a relatively medium water-rich area, a relatively strong water-rich area program. The results of the on-site pumping test were used to correct the qualitative and relative evaluation results.
