Abstract

The invention discloses a guide-rail type soft coal seam working face steel wire mesh conveying device and a using method thereof, and relates to the technical field of coal mining. A hydraulic bracket is arranged between a coal wall and a gob to realize supporting and covering for a coalface; a guide rail locating hanger is arranged at the inner side front part position of the hydraulic bracket;a steel wire mesh is laid above the hydraulic bracket; the rear part of the steel wire mesh is fixed to the bottom of a gangue, and the front part of the steel wire mesh is laid toward the front end along the hydraulic bracket, so that workers are located in a completely closed environment formed by the hydraulic bracket and the steel wire mesh; and the front end of the steel wire mesh bypasses the front end of a face guard of the hydraulic bracket and is connected with a steel wire mesh roll winded on a guide rail through a mesh buckle to realize quick laying of the steel wire mesh. Operationis convenient and fast, the labor intensity of operating staff is reduced greatly, and the efficiency of steel wire mesh laying is improved greatly.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a guide-rail type steel wire mesh transmission device for working faces in soft coal seams and a use method thereof. Background technique [0002] With the continuous increase of mining depth and mining intensity, the technical conditions of mine mining are more complicated, and the problems of soft roof, soft floor and soft coal seam are gradually highlighted. The soft coal seam has low strength and poor structure. , Accidents such as roof caving occurred, and the stability of the coal wall seriously restricted the safe and efficient mining of the coal seam. In order to isolate the broken roof from the coal wall and prevent the broken roof from falling during the lowering of the support and the coal wall from causing harm to the safety of workers, telescopic front beams and side guards are used to push the steel wire mesh on the coal wall. The workers are in a fully closed ...
