Through analyzing the dynamic characteristics of groundwater in Linfen City, this paper points out the main factors influencing the dynamic state of groundwater, and analyzes the dynamic types of groundwater and the typical dynamic process curve of well-water level.

Based on expatiating the dynamic characters of groundwater level,we analyzed the period of groundwater level variation by the spectrum analysis method,also made the optimization on observation frequency of groundwater monitoring network in the plain of Shiyanghe River Basin.

This paper introduces the natural conditions of the mining area,sums up the main characteristics of the aquifer in Lancang Laocang Jamesonite Mining Area,analyzes the groundwater characteristics in the mining area,and makes a thorough investigation on the hydro-geological conditions in the mining area,and obtains better hydro-geological effects.

It indicates that the groundwater chemical characteristics have changed a lot, due to the impacts of five times intermittent water transport.
