Applicable Scope

The mining tunnel repair machine is a crawler-type equipment developed to address the problems of low construction efficiency and unsafe construction operations in underground tunnel repair operations in coal mines. It has multiple functions such as lying down, rock breaking, cleaning, and transportation. This machine is mainly used for the expansion, bottoming, and repair of mining formed tunnels, coal tunnels, semi coal tunnels, semi coal rock tunnels, and rock tunnels.

Product Features

1.The machine has the advantages of small size, compact structure, and high work efficiency. It can be used in conjunction with scraper conveyors to achieve mechanized operation of tunnel repair machines and effectively improve the speed of tunnel repair operations;

2.The working arm can rotate ± 90° along the axis of the machine body, which can meet the requirements of various actions such as excavation, side excavation, flipping, rock breaking, loading, and lifting. It has multiple functions such as digging rough water ditches, lying down, rock breaking, cleaning floating coal, cleaning the bottom of the belt conveyor, leveling tunnels, and lifting small accessories;

3. Driven by a diesel engine, it is simpler, more flexible, safer, and more reliable to operate compared to an electric tunnel repair machine, and is more suitable for high gas and prone to natural combustion mines;

4. The main action is controlled by a pilot valve, which is easy and convenient to operate, so it works smoothly without impact;

5. It can achieve rapid replacement of buckets and crushing hammers, and achieve a series of operations such as crushing, excavation, loading, and transportation in tunnel repair operations.
