摘要
A filling mining method applied to a fully mechanized top coal caving working face. The method comprises: A, dividing the fully mechanized top coal caving working face in the extending direction of the working face into a filling area and a top coal caving area, or dividing the working face in the extending direction and the inclination direction into a filling area and a top coal caving area; B, determining a working face cycle step pitch; C, supporting and protecting the filling area in front of the working face, and when coal caving of the top coal caving area is completed, erecting round wood supports in the filling area; D, after the filling area reaches a filling step pitch, providing a filling tarpaulin behind a hydraulic support, and pumping filling paste; and E, repeating steps C and D to complete the mining. The method solves the technical problems of control over a roof of the fully mechanized top coal caving working face and deformation of a top coal caving mining surface.
