Who must approve the installation of high voltage cables in a mine?

The appropriate authority to approve the installation of high voltage cables in a mine is the MGB Regional Office. This office oversees the operations and safety standards of mining activities within its jurisdiction, ensuring compliance with regulatory requirements and safety protocols. High voltage installations pose significant risks, and thus, they require careful review and approval by specialized regional offices that are familiar with the specific conditions and regulations applicable to mining operations in their area.

The MGB Central Office, while instrumental in broader regulatory frameworks, does not typically handle approvals for specific installations at the local level. The Mine Safety Board primarily focuses on safety assessments rather than installation approvals. Local Government Offices may have roles in permitting and land use but do not have the expertise or authority regarding mine operations to approve high voltage cable installations. Therefore, the MGB Regional Office is the correct entity for this responsibility, ensuring both safety and compliance with mining regulations.
