What shall be provided on all underground (UG) belts?

The requirement for slip and sequence switches on all underground belts is crucial for ensuring the safe operation of conveyor systems in mining environments. Slip switches serve as a safety device that helps detect when a belt is slipping or operating outside of its normal parameters. This monitoring is essential in preventing damage to the equipment and reducing the risk of accidents that could arise from malfunctioning machinery.

Sequence switches, on the other hand, are designed to ensure that the system operates in a specific order. This functionality helps to maintain control and coordination among multiple components of the conveyor system, ensuring that they work together effectively and safely. By having these safety devices installed, operators can mitigate risks associated with unexpected malfunctions or operational failures, thereby promoting a safer underground environment.

While other options, such as increased lighting systems or two-way communication, contribute to overall safety in underground operations, they do not directly address the operational safety and machine integrity concerns that slip and sequence switches specifically tackle. This focus on machinery control and safety is essential in the unique and often hazardous conditions found in underground mining.
