Study on the Application Range of R in the Formulas of Mine Water Inflow
Calculation of mine water inflow is an important content in hydrogeological work: It is one of the main work in deposit hydrogeological exploration.Based on the dynamics of groundwater, the large-well method (LWM) is simple and effective in the prediction of mine water inflow.However, how to reasonably select parameters in LWM has great influence on the results of water inflow prediction.This paper takes the water inflow prediction of panel 2101 in Chaokewula mine as an example, using analytical method and numerical method to explore the formula application range of reference influence radius R.The comparison results show that for confined water it is better to use R =10S√K;if the condition of the aquifer recharge is better or the thickness of confined aquifer is bigger, it is better to use R =10S√K too.The research results provide scientific basis for the calculation of mine water inflow.
