Key problems in solving safety protection of slip mine

Recently, safety rectification Yantai Xintai, Shandong Gold Mining Co., Ltd. mound mix well according to the company's proposed mine safety inspection, carried out underground mine slip "push-pull grille" security reform to address the key issues of security slip of mine, Received the desired effect.

In order to facilitate the prospecting and transportation of mines, the mines are generally located next to the roadway. In order to prevent pedestrians from falling into the mine when passing through the mine, it is necessary to take necessary protective measures for the mine shaft. Prior to this, the company's underground mines were screened on the wellhead as a protective measure. This method is troublesome because the operation of the baffle screen is lifted and covered when the mine is put out, sometimes the operator can not cover the baffle in time in the mine release gap, thus there is a safety hazard; on the other hand, the mine is discharged. During the opening of the screen, the pedestrians passed through the mouth of the mine, there was no isolation measures, and there were also unsafe factors. The company's leaders discovered this problem during the safety inspection of the mound mixed well mining area. Therefore, it was proposed to establish a sliding door between the sliding mine and the roadway to separate the roadway from the slipping mine hole instead of the baffle screen. To this end, the maintenance personnel of the mound-mixed mines in the mining area have designed and researched themselves according to the leadership requirements, and used the reinforced iron control to make the “sliding mine push-pull safety protection barrier”. Three mines in the middle of the mine are installed and used. Usually, the grille door is always closed. When the miner enters and exits, the grille door can be pulled up. When the mine is mined and the mine shaft is open, just pull the grille door and the laneway pedestrian can There is no safety hazard from the side of the mine. Compared with the original baffle screen protection, this modification not only has effective safety protection measures, but also is easy and simple to operate, which fundamentally eliminates the safety hazard of slipping mines.

The company requires other mining areas to follow the practice of the mound mixed mine area, and implement the “push-pull protection grille” transformation for all underground mines to provide a fundamental guarantee for ensuring the safe operation of the mine.
