摘　　要：随着会泽矿区往深部延伸,深边部面临“高水压、大涌水”等安全风险,易导致水害事故发生。为规避水害安全风险,使深部探采工程有序开展。本文通过收集矿区历年水文资料及科研成果,探讨气象水文、地质构造、含水层赋存特征及工程开拓情况等4个方面对矿坑涌水量的影响,并运用模糊层次分析法(FAHP法)建立以大气降雨、岩溶、裂隙构造、含水层厚度、岩层渗透系数、单位涌水量、矿井开采深度、矿井开采面积等8个主控因素建立矿坑涌水量影因响素的层次结构模型。结果表明:在矿坑侵蚀基准面以上大气降雨为矿坑涌水量变化最主要的影响因素,侵蚀基准面以下各影响因素的权重值相差不大。As the Huize mining area extends deeper,the deep periphery faces safety risks such as "high water pressure and significant water inflow," which can easily lead to water hazard accidents.To avoid these water hazard safety risks and ensure orderly progress of deep exploration and mining projects,this paper collects hydrological data and scientific research achievements from past years in the mining area.It discusses the impact of four aspects—meteorological hydrology,geological structure,aquifer characteristics,and engineering development—on mine pit water inflow.Using the Fuzzy Analytic Hierarchy Process(FAHP),a hierarchical structure model is established with eight main controlling factors:atmospheric rainfall,karst,fracture structures,aquifer thickness,rock layer permeability coefficient,unit water inflow,mine depth,and mining area.The results indicate that above the erosion base level,atmospheric rainfall is the most significant factor affecting mine pit water inflow,while below the erosion base level,the weight values of various influencing factors are relatively similar.
