摘　　要：针对寺家庄煤矿开采过程中面临的顶板突水安全问题,本文提出AHP赋权法的评价模型。该模型基于寺家庄煤矿矿井地质、水文地质条件和煤层顶板突水规律,对顶板突水危险性进行评价。选取脆塑岩比、含水层厚度、岩芯采取率、冲洗液消耗量、断层分布、陷落柱分布、断层规模指数七个主控因素作为顶板水评价指标,确定指标综合权重,建立富水性评价模型,并通过GIS进行富水性分区。结果表明,寺家庄煤矿煤层顶板富水性综合分区图为南北区域相对危险,中部区域相对安全。评价结果与实际吻合良好,对矿区安全生产具有重要意义。Aiming at the safety problem of roof water inrush in the process of Sijiazhuang coal mine,this paper puts forward the evaluation model of AHP weighting method.Based on the geological and hydrogeological conditions of Sijiazhuang coal mine and the law of roof water inrush,the model evaluates the risk of roof water inrush.Seven main control factors,brittle-plastic rock ratio,aquifer thickness,core recovery,flushing fluid consumption,fault distribution,collapse column distribution and fault scale index,are selected as roof water evaluation indexes,the index comprehensive weight is determined,and the evaluation model of water-enrichment is established,and the water-enrichment zoning is carried out by GIS.The results show that the comprehensive zoning map of coal seam roof water-rich in Sijiazhuang coal mine is relatively dangerous in the north and south regions,and relatively safe in the middle regions.The evaluation results are in good agreement with the actual situation,which is of great significance to the safety production in the mining area.
