Spiral coal mining machine is the core heavy equipment for underground coal mining, with large size, heavy weight, and precise structure. During underground transportation operations, the tunnel environment is complex and the road surface is uneven. Equipment is prone to shaking, displacement, and collision, which not only causes damage to equipment components and accuracy, but also leads to safety accidents such as tipping and collision, seriously threatening the life safety of underground workers. Therefore, doing a good job in the transportation and fixed operation of spiral coal mining machines is a key link to ensure the safety of equipment transportation and standardize on-site operations.

In the transportation operation of spiral coal mining equipment, the chain block is the core fixed tensioning tool, which has the advantages of convenient operation, stable fastening force, and strong adaptability, and is suitable for equipment fixed operation in complex underground working conditions. Before starting the homework, the staff need to inspect the chain, hook, braking device and other components of the chain hoist in advance, to prevent the use of damaged, malfunctioning, and aging equipment, and ensure that the tool performance is intact, safe and reliable.

When fixing the operation, it is necessary to find the fixed point according to the size and weight of the spiral coal mining machine, and properly mount the chain block between the solid support structure and the equipment fixed lifting point. The chain should be evenly tightened to firmly fix the equipment on the transport vehicle, completely eliminating any loose space for the equipment. The multi-point cross fixation method can effectively resist bumps and shaking during transportation, avoiding collisions and scratches between equipment and tunnel walls and support facilities.

The entire operation must strictly follow the coal mine safety operation regulations, with dedicated personnel operating and monitoring, and real-time observation of the fixed status of the equipment. A stable fixing method can not only protect precision equipment intact and reduce equipment maintenance costs, but also avoid transportation safety hazards from the source, ensuring efficient, safe, and orderly underground transportation operations.
