摘要:
基于矿井涌水量计算及水资源评价需要,首先运用注水试验代替抽水试验,求取了太原组灰岩含水层的渗透系数。根据后期同一含水层井下放水试验资料,利用VISUALMODFLOW建立了水文地质三维非稳定流数值模型,通过分区拟合调参,获得了含水层各分区的渗透系数。通过对渗透系数及其空间分布规律的对比研究,发现渗透系数随含水层埋深增大而逐渐减小。注水试验比放水试验所得渗透系数值小,前者是后者的356%-508%。
Abstract:
Based on the need of mine inflow calculation and water resources evaluation calculation, the water injection test was applied instead of pumping test and the permeability coefficient of TaiYuan group limestone aquifer was calculated. Based on the data of dewatering test, a hydrogeological threedimensional numerical model of unsteady flow was established by using VISUAL MODFLOW software. Through the partition fitting adjustable parameter, the aquifer hydrogeological parameters were obtained. According to the contrastive study on the hydraulic conductivity and its spatial distribution, it was found that the permeability coefficient decreased with the increase of aquifer depth. The permeability coefficient of water injection test was smaller than was dewatering test. the former is 356% to 508% of the latter.
