The Application of Rockbreaker Boom at the Chute Opening of Underground Mines

 

In underground mines, large ore blocks are frequently produced during mining operations and can easily obstruct the chute opening, stopping the flow of ore. Traditionally, small explosives were used to break up these large blocks, but this method is dangerous, costly, and causes major disruptions to operations. A safer and more efficient solution is installing stationary hydraulic mechanical hands at the chute opening.

Stationary hydraulic mechanical hands utilize powerful hydraulic hammers to directly crush large ore blocks into small, manageable fragments that can pass through the chute, allowing for continuous ore transportation without needing to halt operations. By breaking down oversized ore immediately, they prevent blockages from forming and eliminating disruptions. Their remote operation allows workers to operate the mechanical hands from a safe distance away in the confined, hazardous space of the chute opening. 

Compared to using explosives, stationary hydraulic mechanical hands offer significant benefits. They do not require evacuating personnel or stopping the transportation system, allowing ore flow to resume quickly. They also minimize the threat of injury or structural damage from blasting. Hydraulic mechanical hands also provide a continuous solution for managing oversized ore and preventing future blockages, improving productivity. 

• Key Functions

1. Crushing large ore blocks into small fragments to clear existing blockages and restore ore flow promptly without halting the transportation system. By eliminating buildups of oversized ore, they prevent future blockages from forming. 
2. Continuously monitoring the ore stream and crushing any oversized blocks to ensure the uninterrupted flow of appropriately-sized ore through the chute. By immediately breaking down large blocks before they accumulate, they enable non-stop ore transportation. 
3. Being remotely controlled to operate in hazardous, confined spaces while the operator remains at a safe distance. Workers are shielded from the dangers of operating heavy equipment in restrictive areas with poor visibility.

Overall, stationary hydraulic mechanical hands are ideal for solving blockage issues at the chute opening of underground mines. Their capability to remotely crush large ore into small particles enables safer, higher-volume operations. By eliminating the use of explosives, they remove major interruptions to ore transportation. Stationary hydraulic mechanical hands are critical tools for productive mining.
