Groundwater Dynamics Method of Mine Discharge and Its Parameter Analysis

Abstract

Absrtact. Mine discharge refers to the total amount of surface water, fissure water, old kiln water and karst water inflow into the mine roadway. It is an important indicator in the process of coal mine production safety, and also the focus of scholars' attention. Based on a large number of previous research results, this paper introduces the groundwater dynamic method of mine discharge, analyses the parameters in the theoretical formula, discusses the influence of the change of parameters on mine water inflow, and provides a reference for further understanding the calculation of mine discharge.
