Abstract

The invention discloses an eliminating facility for accumulated water threat of adjacent goafs of a working face and an implementation scheme. The eliminating facility comprises a plurality of drilling machine chambers arranged on a coal wall, close to the adjacent goafs, of one side of a transportation gate road or an air return gate road of a working face, the plurality of drilling machine chambers are sequentially arranged at intervals from high to low along the transportation gate road or the air return gate road of the working face according to the fluctuation condition of a roadway bottom plate, a plurality of drilling holes are formed in each drilling machine chamber, the plurality of drilling holes extend into a coal seam of the adjacent goafs from the drilling machine chambers, wherein an included angle is formed between the plurality of drilling holes of each drilling machine chamber in the case of overlooking from the top of the roadway to the bottom, and an upward included angle is formed between each drilling hole and the roadway bottom plate. According to the eliminating facility for the accumulated water threat of the adjacent goafs of the working face, the accumulated water of the adjacent goafs of the working face can be effectively drained, and the goaf accumulated water threat is thoroughly eliminated.

Description

technical field [0001] The invention relates to the field of maintenance of fully-mechanized mining areas in coal mines, in particular to a facility and a scheme for eliminating the threat of water accumulation in adjacent goafs of working faces. Background technique [0002] The coal seams of coal mines often contain different degrees of accumulated water. If such accumulated water in each layer is not scientifically dredged, it will bring a lot of inconvenience to fully mechanized mining. For example, the 1119 working face of Xichuan Coal Mine is located in the west wing of the first mining area. The working face is adjacent to the goaf of the 1121 working face in the north and the 1117 working face that has been mined in the south. boundary. The strike length of the working face is 1250m, and the width of the working face is 150m. The No. 4 coal seam is mined in the working face, the coal seam structure is medium, the overall shape is a small syncline structure, and the...
