Abstract

The invention provides a reinforcing and sealing device of a mine opening for blasting inside a mine, and belongs to the technical field of coal mine engineering. The reinforcing and sealing device comprises a screw, a sealing device, a movable device and a reinforcing device, wherein the sealing device comprises a fixed plate and a plurality of bolts, and the fixed plate is fixedly connected withthe mine opening through the bolts; the movable device is rotationally connected with the fixed plate, and the reinforcing device moves up and down in the mine through the movable device; the top ofa mounting plate is fixedly provided with mounting grooves with cavity bodies, and a side gear is rotatably connected with a mounting shaft; two racks are arranged at two sides of the cavity body of each mounting groove in a matched manner, the racks are respectively meshed with two side gears, a main gear is arranged at the top of each mounting groove, and the two side gears are meshed with the main gear; and one end of the screw is fixedly provided with a first nut, and the other end of the screw drives the main gears to rotate to realize the movement of the two racks. According to the reinforcing and sealing device, the mine opening can be sealed during blasting, and the mine opening is supported and reinforced through rack support.

Description

Technical field [0001] The invention relates to the technical field of coal mine engineering, in particular to a reinforcement sealing device used for blasting in a mine to a mine head. Background technique [0002] In the process of coal mining, it is necessary to excavate from the ground to the underground to form a series of shafts and lanes to various mining areas. Commonly used mine development is usually divided into flat tunnel development, inclined shaft development and vertical shaft development according to the structure of the shaft. The common development method is tunneling. However, in actual mining and tunneling, the mine must first be blasted to facilitate the search for development points. During blasting, to protect the lives of mine workers, it is necessary to support or even reinforce the entrance. [0003] In order to avoid the collapse of the mine entrance and the influence of the surrounding environment during mine blasting operations, the wellhead needs to ...
