What must contractors do before new underground mining approval?

Before any new underground mining activity can commence, it is essential for contractors to contact the inspector. This step is crucial as the inspector is responsible for assessing safety measures, regulatory compliance, and the overall preparedness of the mining operation. Engaging with the inspector helps to ensure that all necessary regulations and safety protocols are understood and adhered to. This communication can facilitate the approval process by addressing any potential concerns or prerequisites that need to be met prior to beginning operations.

The other options, while potentially important steps in the overall process of securing approval, do not replace the necessity of establishing direct communication with the inspector who oversees the safety and regulatory frameworks associated with underground mining.
