Abstract
According to the occurrence and geological conditions of the coal seam in the island working face of 31321, the section and support mode of the working face roadway are designed, and the method of the front-plate support and the forward support method in the smooth groove are determined. This paper discusses the concrete scheme of overworked roadway and fault, and puts forward some countermeasures.关键词
