What must be included in the 'notice of intention to seal mine'?

• A. Proposed sealing procedure
• B. Location of seals and area to be sealed
• C. Any evidence of ignition sources present in the area to be sealed
• D. All of the above

Answer: (D)

All of these elements must be included. A notice of intention to seal a mine needs the proposed sealing procedure so the steps, controls, and responsibilities are clear and implementable, ensuring the sealing is done safely and without compromising other workings. It also requires the exact location of the seals and the area to be sealed so everyone knows precisely what part of the mine is affected and so barricades and access controls can be correctly applied. Including any evidence of ignition sources present in the area to be sealed is crucial for risk assessment and mitigation, guiding actions to eliminate or isolate sources of ignition and to adjust monitoring or ventilation controls as needed. Together, these details provide a complete, safe, and compliant plan for sealing.
