| Abstract: | Water hazard from roof is one of the hazards threatening the production of working face.This paper takes the water inflow conditions in 14310 fully mechanized and roof caving working face of Dongtan mine as example.On the basis of analysis of the geological and hydrogeological conditions,the water inflow of mine working face is forecasted according to the water-bearing mechanism of the structures.The engineering of water detection and drainage,drainage tunnel and drainage system are implemented for safe caving in the 14310 working face.And the mine safety has been realized in the working face finally. |
