| 摘 要： | 针对田陈煤矿3下煤层顶板含水层富水性开展研究,选取了砂岩岩性系数、岩性结构指数、岩芯采取率、断层分维值、褶皱分维值等5个参数作为砂岩含水层富水性预测的评价指标,并利用AHP-PCA法对主控因素对富水性的影响进行了综合赋权,得到权重,在此基础上基于TOPSIS多属性建立了富水性指数预测模型,实现了煤层顶板含水层富水性预测...

| Abstract: | Based on the study of water richness of the 3;coal seam roof aquifer in Tianchen Coal Mine,five parameters such as sandstone lithology coefficient,lithologic structure index,core recovery rate,fault fractal dimension and fold fractal dimension are selected as the evaluation indexes for the prediction of water richness of sandstone aquifer.The influence of main controlling factors on water richness is comprehensively weighted by AHP-PCA method,and the weight is obtained.On this basis,based on the multi-attributes of TOPSIS,the prediction model of water richness index is established,and the prediction zone of water abundance of coal seam roof aquifer is realized,which provides a basis for safe and efficient coal seam mining. |
