摘　　要：大同焦煤一矿顶板水害问题严重影响了煤矿正常生产和人员安全,为准确评价顶板含水层的富水性分布特征,采用井下网络并行电法技术系统探测了二叠系石盒子组含水层中导水裂隙带的高度,基于沉积物控制法分析含水层的平面展布、横向空间分布特征,构建沉积环境影响指数、砂泥岩夹层比、砂岩厚度、地球物理水体丰富度异常指数四个关键指标的评价体系,引入层次分析法(AHP)进行权重分配绘制综合区划图进行评价。结果表明:评价体系能够准确划分出顶板含水层的富水性区域,并通过矿井涌水量的实测数据进行了有效验证,评价结果与实际抽水试验结果具有较好的一致性。The problem of roof water damage in Datong Coking Coal No.1 Mine seriously affects the normal production and personnel safety of the coal mine.In order to accurately evaluate the water-richness distribution characteristics of the roof aquifer,the downhole network parallel electrical method technology system is used to detect the height of the water conducting fissure zone in the Permian Shihezi Formation aquifer.Based on the sediment control method,the planar distribution and lateral spatial distribution characteristics of the aquifer are analyzed,and an evaluation system is constructed for four key indicators:sedimentary environment impact index,sand mudstone interlayer ratio,sandstone thickness,and geophysical water body richness anomaly index.The Analytic Hierarchy Process(AHP)is introduced for weight allocation to draw a comprehensive zoning map for evaluation.The results show that the evaluation system can accurately divide the water-richness areas of the roof aquifer,and effectively verify them through the actual measured data of mine water inflow.The evaluation results have relatively good consistency with the actual pumping test results.
