Abstract

The invention belongs to the technical field of coal roadway advance support, in particular to a coal roadway full-section self-moving advance temporary support device and a support method. It includes a support device and a support device. A push jack is arranged between the support device and the support device. The support device includes a base symmetrically arranged on both sides. A column is installed on the base. The top of the column is connected to the support beam through a jacking jack. The left and right connecting sleeves are provided with a push-pull rod inside the sleeve, the outer end of the push-pull rod is connected to the support body, and the inner end of the push-pull rod is connected with a two-way telescopic jack; the support device includes a base symmetrically arranged on both sides, and a column is installed on the base. The top of the column is connected to the support beam through the lifting jack. The telescopic beam jack is installed in the support beam. The telescopic beam jack drives the telescopic beam to extend forward. The outer end of the pull rod is connected with the support body, and the inner end of the push-pull rod is connected with the two-way telescopic jack.

Description

technical field [0001] The invention belongs to the technical field of coal roadway advance support, in particular to a coal roadway full-section self-moving advance temporary support device and a support method. Background technique [0002] Due to the mining disturbance in the mining process of the working face, the bearing pressure in front of the working face and the residual bearing pressure of the roadway in the mining roadway, the mine pressure in the mining roadway is particularly severe, resulting in serious deformation and damage of the roadway, and the support equipment near the working face roadway is easily damaged The bottoming of the press frame or support will bring safety hazards to the normal and safe production of the working face. At present, most coal mines use single pillars and beams for auxiliary support, and the support effect is obvious. The front end of the body pillar is used for the next section of roadway support. The efficiency of manual frame...
