摘 要:对含水层富水性进行分析评价,是煤矿开采、隧道掘进时防止涌(突)水发生的重要前提。通过分析影响含水层富水性的因素,以某煤矿为例,选取含水层厚度、钻孔冲洗液消耗量、构造发育密度、单位涌水量及渗透系数五个指标进行分析;引入模糊层次分析法确定各因素对含水层富水性影响的权重;应用GIS的数据管理和空间分析功能,计算评价了研究区的富水性;将研究区含水层按富水性强弱分为五个区域。评价分区结果与研究区水文地质条件变化基本一致。为区域含水层富水性评价提供了一种新思路。To prevent water bursting from mining coals and boring tunnels,analyses of water abundance for an aquifer has to be done firstly.Based on analyses of main factors that can influence the water abundance of the aquifer,five indices are used: aquifer thickness,drilling flush fluid consumption,developing density of structures,unit-inflow and permeability coefficient.The fuzzy analytic hierarchy process is introduced to determine the weight of each factor.Combining the data management and spatial analysis of GIS,we calculate and estimate the characteristics of water abundance in the study area.Due to the wide variance in water abundance over the whole study area,we set five rates to show the different results.As a result,the study area can be divided into five parts whose capability of accommodating water ranges from strong to weak.Fortunately,the division is consistent with the hydrogeological conditions and measured water inflow.Therefore the method is an alternative one.
