摘　　要：以淮南某煤矿为例,通过对新生界底部含水层的水文地质条件和突水动态分析,建立了水文地质概念模型和数学模型,利用井壁破裂后的底部含水层突水观测资料,运用GMS软件对模型进行识别和验证,得到了模型的分区参数值,验证后的模型为后期注浆工艺设计和工程施工提供了依据。Give a mine in Huainan as an example,through analysis of hydrogeological conditions and water inrush dynamic trends at the bottom aquifer of Cenozoic strata,a hydrogeological conception model and a mathematical model are established.By using water inrush observation data of the bottom aquifer obtained after shaft wall fractured,and GMS software,these models are identified and verified,relevant partition parameters are obtained.The verified models hence are used as a base for designing grouting processes and construction engineering.
