摘　　要：以山西省某煤矿矿井抽水区引起的地面沉降为例,采用多物理场耦合分析软件Comsol Multiphysics中的多孔弹性物理场接口,基于Boit固结理论,建立矿井抽水区-地面沉降流固耦合模型。通过分析计算及位移拟合,分析其产生沉降的原因以及动态降水的时间与空间效应,目的在于为今后矿井抽水区地面沉降的防治提供依据和技术指导。A coal mine in Shanxi province land subsidence caused by pumping area as the example, using multiple physical field coupling analysis software Comsol Multiphysics porous elastic physical fields in the interface, based on Bolt Consolidation theory, establish the mine area - land subsidence of fluid-solid coupling model of pumping. Through analysis and calculation and analysis of displacement fitting, the causes of sedimentation and dynamic precipitation effect of time and space, the purpose is for future mine water area provides the reference for the prevention of land subsidence and technical guidance.
