A Reinforcing Method to Prevent the Lining of Mine Bin from Falling off

Abstract

The invention discloses a strengthening method for preventing detachment of lining of an ore storage bin. The strengthening method for preventing the detachment of the lining of the ore storage bin adopts a row of components for strengthening-steel rails (7), the steel rails (7) are vertically arranged on the side face of a frontal wall of the junction of the ore storage bin (2) and a crusher chamber (1), components for strengthening further comprise box iron (6), a U-shaped anchor bar (8), a box iron anchor bar (9), bolts, wedge-shaped base plates, pressing plates, nuts and base pads, and they together form a bracing frame; the box iron (6) is horizontally arranged along the steel rails (7) from top to bottom in a transverse mode; the bracing frame is entirely injected in concrete to form a whole. The bracing frame adopted by the strengthening method for preventing the detachment of the lining of the ore storage bin has the advantages that the structure is simple, the installation is convenient, the possibility that the bolts are prone to be smashed is reduced, the firmness of the steel rails (7) is guaranteed, no welding point occurs in installation, the working condition is good, and the bolts and the pressing plates are easy to purchase; the U-shaped anchor bar and the pressing plates can effectively prevent the detachment of the lining of the ore storage bin to enable the ore storage bin to work normally. The strengthening method for preventing the detachment of the lining of the ore storage bin can be applied in underground primary bins and ore treatment plant earth surface skip ore storage bins.

Description

Technical field [0001] The invention relates to a method for preventing the lining of a mine bin from falling off, which is particularly suitable for mine bins with an underground crushing system, especially the reinforcement of the lining of the front wall of the mine bin adjacent to the crushing chamber, which can be used in underground mine bins and concentrators Application in reinforcement of surface skip ore bin. Background technique [0002] In the underground mining production process, in order to ensure the continuity of production, some transportation equipment and loading equipment have strict requirements on the ore lumpiness. For this reason, a crushing system is set up underground, and the ore is sent from the middle chute to the middle position before the crusher. Mine warehouse. Because the ore is hard and large in size, the ore warehouse has the following problems in use: the ore will impact the forehead wall when it is poured into the ore warehouse, and it will...

AI Technical Summary

Problems solved by technology

Due to the hard ore and large lumps, there are the following problems in the use of the mine bin: the ore will hit the forehead wall when it is poured into the mine bin, and it is easy to hit the forehead wall after a long time of impact, so that the mine bin and the chamber If it penetrates, it will cause the mining enterprise to stop production, and even hurt people.

When the reinforcement methods mentioned above are used to strengthen the lining of the front wall of the mine adjacent to the crushing chamber, due to the difference in steel materials and the complexity of the site conditions, the steel rails at the front wall of the mine are extremely prone to vibration or damage. The impact and fall off, that is, the inner lining falls off, which will cause the blockage of the mine bin, and the forehead wall will be worn through, which will affect the production of the enterprise and the safety of personnel.
