以X矿3_(-1)煤顶板含水层富水性主控因素数据为例,分别采用4种不同无量纲化方法得到了相对应的4种富水性评价结果,结果表明,不同无量纲化方法处理结果总体趋势一致,局部小范围存在一定的差异。采用斯皮尔曼等级相关系数对不同无量纲方法进行相关性分析,最后得出平均化处理方法更加合理。
Taking the dominant water-bearing factors of the 3_ (- 1) coal seam roof in X ore as an example, four different non-dimensional methods were used to obtain the corresponding four kinds of water-rich evaluation results. The results show that different dimensionless methods The overall trend of treatment results are consistent, there are some local small differences. The correlation between different dimensionless methods was analyzed by Spearman’s rank correlation coefficient, and finally the average method was more reasonable.
