Description

Technical Field

[0001] This utility model relates to the field of coal mine engineering technology, specifically to a platform for installing anchor cables and wire mesh at the end of mining operations. Background Technology

[0002] In the unmined areas of coal mines, installing anchor cables and netting is a crucial safety measure. It can effectively prevent accidents such as coal falling, roof rock falling, and local collapses during the mining process, providing miners with a relatively safe working environment. At the same time, it can also stabilize the roof, reduce movement, and further improve safety.

[0003] Currently, when installing anchor cables in the unmined areas of high-extraction working faces, scaffolding is usually required as a platform for working at height because the roof of the working face is high above the ground. However, there are usually many collapsed coal piles on the side adjacent to the coal seam, which will interfere with the erection of the scaffolding and make it difficult to move the scaffolding. Cleaning up the coal piles is time-consuming and labor-intensive. Therefore, we propose a platform for installing anchor cables with netting in the unmined areas. Utility Model Content
