What action is restricted within 16 meters of the main shaft?

• A. Stopping the train
• B. Starting the train
• C. Overtaking another train
• D. Performing maintenance

Answer: (A)

In the area close to the main shaft, safety rules are designed to keep the hoisting path clear and prevent blockages or collisions. The 16-meter zone is a critical clearance where a stationary train could be struck by an approaching cage or skip, or obstruct the passage used by the hoist and other trains. Stopping a train there could trap personnel, delay hoisting operations, and create a dangerous bottleneck in this essential corridor. Keeping movement continuous helps ensure the shaft can operate safely and predictably. Starting, overtaking, and maintenance have their own procedures, but the specific restriction aimed at preventing these near-shaft hazards is to avoid stopping the train in that zone.
