为解决传统富水性评价中遇到的水文地质试验孔较少,不能有效反映含水层富水性区划以及影响因素的不确定性问题,应用沉积控水规律,构建含有砂泥质量比、卵砾石层厚度、卵砾石层层数以及含水层厚度4个指标的评价体系,采用综合赋权法和多指标综合未确知测度理论耦合评价模型对第四系底部松散含水层的富水性进行评价,进而确定浅部煤层水体下安全煤岩柱留设类型,最后以蔚县矿区单侯矿井进行实例分析.结果表明:该方法能有效地实现松散含水层的富水性区划,为保水采煤分区研究中的含水层富水性评价提供了新思路.
In order to solve the problem of less hydrological test holes encountered in traditional water-rich evaluation, and can not effectively reflect the uncertainties of water-rich regionalization of aquifer and its influencing factors, Thickness, the number of layers of gravel and the thickness of the aquifer, the comprehensive evaluation method was used to evaluate the water-bearing capacity of loose aquifers at the bottom of the Quaternary system by using the comprehensive evaluation method and the multi-index unascertained measurement theory coupled evaluation model The type of safe coal and rock pillar in shallow coal seam water body is determined, and finally the case study of single coal mine in Yuxian mining area is carried out.The results show that this method can effectively realize the water-rich regionalization of loose aquifer, Aquifer water-rich evaluation provides a new idea.
