Abstract

The invention provides a reinforcement and sealing device for blasting mine mouths in mines, which belongs to the technical field of coal mine engineering and includes a screw, a sealing device, a moving device and a reinforcement device; the sealing device includes a fixed plate and several bolts; the fixed plate passes through the bolt It is fixedly connected to the wellhead; the mobile device is connected to the fixed plate in rotation, and the reinforcement device moves up and down in the well through the mobile device; the top of the mounting plate is fixed with a mounting groove with a cavity, and each side gear is respectively connected to a mounting shaft in rotation; There are two racks on both sides of the cavity of the installation groove, and each rack meshes with two side gears respectively. The main gear is set on the top of the installation groove, and the two side gears mesh with the main gear; one end of the screw rod is fixed A first nut is provided, and the other end of the screw rod drives the main gear to rotate to realize the movement of the two racks. The device can seal the wellhead of the mine during blasting, and support and reinforce the wellhead through the support of the rack.

Description

technical field [0001] The invention relates to the technical field of coal mine engineering, in particular to a reinforcement and sealing device used for mine head blasting in mines. Background technique [0002] In the process of coal mining, it is necessary to excavate from the ground to the underground, forming a series of wells and lanes, until each mining area. Commonly used mine development is usually divided into flat hole development, inclined shaft development and vertical shaft development according to the structure of the wellbore. The common development method is excavation. However, in the actual mining and excavation, the mine needs to be blasted first, so as to find the development point. In order to protect the safety of the mine workers during blasting, the entrance needs to be supported or even reinforced. [0003] In order to avoid the collapse of the mine entrance and the influence of the surrounding environment during the mine blasting operation, the w...
