What is the maximum speed for belts transporting miners with an 18" minimum overhead clearance?

The maximum speed for belts transporting miners with an 18-inch minimum overhead clearance is determined based on safety regulations established to protect the miners and ensure safe transportation. The chosen speed of 250 feet per minute is consistent with safety standards, allowing for effective operation while minimizing risk.

Higher speeds could pose increased hazards, such as a greater likelihood of accidents due to sudden stops or the difficulty of navigating safely when transported. Moreover, maintaining a controlled speed ensures that miners can board and disembark from the belt safely, which is crucial in maintaining overall safety standards in the mining environment.

Understanding the importance of this limitation is essential for mine foremen and safety personnel to ensure compliance with regulations and to safeguard the well-being of all miners involved in the transportation process.
