Starting with the elevation of underground water resources and a safe level of mining through variable system theory, this paper analyzes the conditions of underground water resources based on the well-studied determination method of determining the two hydrographical coefficients: rainfall infiltration replenishment rate and irrigation replenishment rate. Then considering irrigation, rainfall, drainage and other related factors, a mathematical model is set up for the calculation of underground water storage,exploitation on water regulation. After analyzing the adaptability of molepipe drainage, an underground water table regulation is given out.
