The General Office of the National Mine Safety Administration recently issued a notice specifying the scope and relevant requirements for the “five key leaders” and “five categories of technical personnel” in mines. The full text is as follows:

To implement the Hard Measures to Prevent and Curb Major and Serious Production Safety Accidents in the Mining Sector issued by the Work Safety Committee of the State Council, the National Mine Safety Administration has recently clarified the scope and relevant requirements for the “five key leaders” and “five categories of technical personnel” in mines (see attachment). These are hereby issued to you for implementation and execution. Provincial-level mine safety supervision departments are requested to communicate this notice to mining enterprises within their jurisdictions.

Scope and Relevant Requirements for the “Five Key Leaders” and “Five Categories of Technical Personnel” in Mines

I. Underground Coal Mines

The “five key leaders” refer to the mine manager, chief engineer, and deputy mine managers in charge of safety, production, and electromechanical affairs. These five individuals must have a college degree or above in a core discipline and at least 10 years of frontline experience in the mining industry.

The “five categories of technical personnel” refer to technical staff in the functional departments of production technology, ventilation, electromechanical transportation, geological surveying, and safety management. The heads of these five functional departments must have graduated in a core discipline and have at least 5 years of frontline experience in the mining industry.

II. Surface Coal Mines

The “five key leaders” refer to the mine manager, chief engineer, and deputy mine managers in charge of safety, production, and electromechanical affairs. These five individuals must have a college degree or above in a core discipline and at least 10 years of frontline experience in the mining industry.

The “five categories of technical personnel” refer to technical staff in the functional departments of production technology, dispatching, electromechanical transportation, geological surveying, and safety management. The heads of these five functional departments must have graduated in a core discipline and have at least 5 years of frontline experience in the mining industry.

III. Metal and Non-Metal Underground Mines

The “five key leaders” refer to the mine manager, chief engineer, and deputy mine managers in charge of safety, production, and electromechanical affairs. These five individuals must have a college degree or above in a core discipline and at least 10 years of frontline experience in the mining industry.

The “five categories of technical personnel” refer to technical staff in the functional departments responsible for production technology, ventilation, electromechanical transportation, geological surveying, and safety management. The heads of these functional departments (considering that in most metal and non-metal underground mines, one functional department may be responsible for multiple tasks, the number of functional departments may not be exactly five) must have graduated in a core discipline and have at least 5 years of frontline experience in the mining industry.

IV. Metal and Non-Metal Surface Mines

The “five key leaders” refer to the mine manager and the deputy managers responsible for technology, safety, production, and electromechanical affairs. These individuals (not necessarily five) must have a college degree or above in a core discipline and at least 10 years of frontline experience in the mining industry.

The “five categories of technical personnel” refer to technical staff in the functional departments responsible for production technology, dispatching, electromechanical transportation, geological surveying, and safety management. The heads of these functional departments (considering that in most metal and non-metal surface mines, one functional department may be responsible for multiple tasks, the number of functional departments may not be exactly five) must have graduated in a core discipline and have at least 5 years of frontline experience in the mining industry.
