Mine management must be vested in a sole qualified manager, with owner instructions routed and confirmed in writing. Every mine must be under a sole manager with qualifications prescribed by the Central Government; the owner or agent must appoint a qualified manager and may appoint themself only if qualified. The manager is responsible for overall management, control, supervision and direction of the mine, and any instructions by the owner or agent affecting statutory duties must be confirmed in writing. Except in emergencies, the owner, agent, or their representative shall not give instructions to mine employees affecting the manager's statutory duties other than through the manager.
