摘要
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。以此计算矿坑的涌水量能较好的反映灰岩直接底板与粘性土底板充水的差异性 ,反映粘性土底板厚度以及粘性土底板渗透性能对充水量的影响 ,并能将两种底板混杂分布时的复杂运算简单化 ,较好地解决了矿坑涌水量的计算问题 。
The allotment of Debao bauxite was taken for an example in this article. 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. This method could exactly illuminate the gushing otherness between clay soil base and limestone base, the thickness of clay soil base, the effect of clay soil base nature on the amount of gushing, and simplify the calculations during the conditions that clay soil base mixed with limestone base. It was useful to resolve the problem of gushing evaluation in the mines and could be scientific data for mining.
