为了准确评价矿山深部开采发生的突涌水问题,利用矿区实际勘测水文地质资料,选取了水头差、富水性、渗透系数、含水层厚度、水压值、断层强度和岩溶分带等7个突水主控因素,从充水水源和导水通道两方面进行综合分析.使用AHP-熵权法计算各个主控因子的权重,进而通过G1S空间叠加分析确定突涌水危险性等级,并作出分区图.结果表明,在水源充足和断层发育强的地方,突涌水危险性高.评价结果与矿井实测突水涌水点相符合,证明了该方法的科学性和实用性,可为矿井今后进行资源开采和治理水害工作提供参考.
Evaluation of Water Inrush Risk Level in Deep Mining Based on AHP-entropy Weight Method and GIS
In order to accurately evaluate the problem of water gushing in deep mining,this paper selects seven main controlling factors of water inrush,including water head difference,water richness,permeability coefficient,aquifer thickness,water pressure value,fault strength and karst zonation,and makes a comprehensive analysis from two aspects:water source and water channel.The weights of each main control factor were calculated by AHP-entropy weight method,and then the risk level of water gushing was determined by GIS spatial superposition analysis and the zoning map was made.The results show that the risk of water gushing is high in the place with sufficient water source and strong fault development.The evaluation results are consistent with the measured water gushing point of the mine,which proves the scientificity and practicability of the method,and provides a reference for the resource exploitation and water disaster control work in the mine.
