The Water Inflow Prediction Methods of Working Face Under Different Mining Conditions of Shallow Coal Seam

The paper studies a prediction method conformed practical water inflow features for working face, the method can fully reflect the overburden failure height, the number of aquifers, parameters of working face, hydrogeological parameters and other related parameters in different propulsion sections of working face, which provides basis for scientific layout of working face drainage system and ensures working face water inflow in controllable range.
