1) limestone base
灰岩底板
1.
We tried to adopt equivalent infiltration theory to calculate the area of clay soil base equally to that of clay less soil close-by limestone base, when we employed analytical method to calculate how much water gushing from the mime walls where there was clay soil close-by limestone.
文章以德保铝土矿巴头矿段为例 ,在采用分析计算法计算矿体底板有粘性土与下伏灰岩相隔部分的矿坑涌水量时 ,尝试采用等效渗透原理 ,把粘性土底板面积等效为无粘性土相隔的灰岩底板面积计算。
2) underlying limestone
基底灰岩
