摘　　要：在煤矿开采规模、强度以及深度不断增加的背景下,矿井所面临的水文地质条件呈现多样性,工作面涌水动态演化特征及影响因素也变得更为复杂。以钱营孜煤矿褶曲和断层构造较发育的W3233工作面为研究对象,采用影响因素分析、三维地震勘探方法,探讨了采动影响下工作面涌水动态演化特征,并对矿井水位动态影响因素进行分析。矿井水位动态影响因素主要存在自然因素与人为因素两大类,自然因素包括了地质因素和地表因素,通过构建含水层水位影响因素层次结构体系,利用层次分析法计算出各影响因素的影响权重,其中地质构造、矿井疏放水、注浆治理分别为0.3543,0.2867,0.1433。Under the background of the increasing scale,intensity and depth of coal mining,the hydrogeological conditions faced by coal mines show diversity,and the dynamic evolution characteristics and influencing factors of water gushing at working face become more complex.Taking the W3233 working face with more developed fold and fault structure in Qianyingzi Coal Mine as the research subject,the dynamic evolution characteristics of water gushing in working face under the influence of mining are discussed by the methods of influencing factor analysis and three-dimensional seismic exploration,and the dynamic influencing factors of mine water level are analyzed.There are two main influencing factors of mine water level,natural factors and human factors.Natural factors include geological factors and surface factors.By constructing the hierarchical structure system of influencing factors of aquifer water level,the weight of each influencing factor is calculated by using analytic hierarchy process.The geological structure,mine water drainage and grouting treatment are 0.3543,0.2867 and 0.1433 respectively.
