Calculation of Mine Water Inflow and Cite Influencing Radius of Hetaoyu Coal with “Virtual Large Diameter Well” Method

Abstract:

Calculation of mine water inflow and influencing radius is one of studies of hydrogeology conditions of mining area. Hetaoyu Coal Mine is located in discharge region of lower Cretaceous Luohe Formation aquifer in Qingyang City of Gansu Province. The water inflow and influencing radius are computed by the “Large diameter well” formula of artesian water with “virtual large diameter well” method is based on Dupuit formula. The drill hole radius is replaced by Cite Radius and the influencing radius is replaced by Cite Influencing Radius in calculation process. The scope of groundwater cone is confirmed by cite influencing radius.
