How often must mine maps be extended if within two hundred feet of oil and gas wells?

Mine maps must be extended every six months if they are within two hundred feet of oil and gas wells. This requirement is crucial for various reasons. First, it ensures that the mine's layout is up-to-date, which is essential for safety operations, especially when mining activities are in proximity to oil and gas wells that may have specific regulatory and safety considerations.

Accurate and current mapping allows for better planning and management of mining activities, reducing the risk of accidents and enabling more effective communication with regulatory bodies. This frequent updating helps ensure that any changes in the mine's structure or surrounding environment are documented, which is vital in responding to hazards that may arise due to the proximity of oil and gas operations. The six-month interval strikes a balance between maintaining updated maps and the practicalities of the mining operation.
