摘　　要：在综合分析矿山水害通道的形成和工程影响因素等基础上,以突水通道脆弱性为评价对象,综合选取断层倾角、断层地质特征、裂隙规模、裂隙张开量、裂隙填充成分、隔水关键层抗压强度、渗透系数、厚度、水压、水量、开采强度等11个指标,采用AHP和模糊数学的方法,构建矿山突水通道脆弱性的5级评价体系。研究结果表明:①选取的各因素指标能够体现突水通道的特性,评价方法能够获得地下矿山突水通道脆弱性等级的判定。②以某矿山采场的工程实例评价,其结果与突水系数法一致,证实该指标体系合理可行,能够为矿山的突水灾害进行前期的预警分析。On the basis of comprehensive analysis on the developing law and engineering factors that influence water-conducting, water-conducting vulnerability assessment index system of five levels is established based on the principles of AHP （Analytical Hierarchy Process） and fuzzy mathematics, which considering fault structural fea- tures, fault dip, the scale and the opening volume of fissure, ingredient of fillings in fissure opening, compressive strength, permeability and thickness of impermeable critical layer, the pressure and total amount of water and min- ing intensity. It is shown that： （~） The factor index selected to reflect the characteristics of the water-conducting e- valuation method is available to obtain the level of vulnerability of water-conducting determination in underground mining. （~） The result received from this assessment system based on engineering cases is as same as the water inrush coefficient method, proving that the assessment system is reasonable and practicable. The assessment system is able to provide a method for early warning analysis of mine water disasters.
