| 摘 要： | 采区安全开采受底板徐灰水，奥灰水威胁，确定含水层的富水性和准确的水文地质参数对于评价采区安全开采，评价徐灰水疏水降压可行性，正确预计工作面涌水量均具有重要的意义。基于有限元剖分方法的FEFLOW软件能对地下水流向进行模拟．其内置的PEST能有效地对模型的参数最优化，达到精确求参，从而增加模型的可行性和与实地水文地质条件的拟合度。

| Abstract: | The safe of mining area is threatened by bootom water from xu limestone and Ordovician limestone.Determining the water abundance of aquifer and accurate hydrogeologic parameters is critical for safe coal mining,estimation of xu limestone water dewatering and depressurization,as well as prediction on water inflow of mining face.FEFLOW is widely-used codes for groundwater modeling which is based on finite element method.The PEST package inside can obtain and optimum the model parameters,such that increasing t... |
