How frequently must the map of the coal mine be updated?

The requirement to update the map of the coal mine twice annually, specifically on or before the 1st of March and 1st of September, is established to ensure that the map reflects any changes in the mine's layout, operations, and safety features. This biannual update schedule allows for the incorporation of new information that is vital for the safety and operational efficiency of the mine.

By updating the map at these specified intervals, mine foremen and other responsible personnel can accurately identify critical details such as the location of working areas, mineral deposits, and any hazards that may arise. Maintaining an up-to-date map is crucial not only for compliance with regulations but also for the overall safety of the workforce.

This specific timing aligns with operational cycles and typically allows for adequate time to assess any changes that may have occurred in the mine during the previous six months. Regular updates facilitate better planning and prepare the workforce to respond swiftly to any situations that may arise due to changes in the mine's structure or operations.
