Abstract: Hydrogeolgical parameters are important indices of aquifer characteristics and water abundance evaluation. However, the artificial calculation process is extremely cumbersome, and the cyclic iteration of formula always makes mistakes then will cause immeasurable damages. In view of this, the Visual Basic 6.0 which has powerful compiler and visualization function was applied to convert the complex hydrogeolgical parameters calculation and iteration process into program code. Based on pumping test, finally, a set of specialized software was successfully developed to calculate hydrogeolgical parameters and evaluate water abundance. This software has been well applied in the supplementary geological prospecting of A1 coal seam in the second mining district of Xieqiao coal mine.
