For Ordovician limestone structure and karst growth,they seriously endanger the safety mining of many mine fields.The outflow test and numerical simulation method can find out the main hydro-geological character of the aquifer effectively.In the paper,the numerical simulation on certain mine field was carried on which is based on the idea of domain decomposition method.According to distribution and property of main structure,it chooses the continuous conditions of flux in the interface to divide the original problem into subdomain problems.In each sub-domain,the problem is solved by the finite element method.The result shows that the domain decomposition method is effective to apply on the simulation of groundwater flow in mine area's aquifer.
