1, the management personnel of the mining authority or production team are full-time (no personal labor), only responsible for organization, supervision and inspection, which is relatively easy.

2. On-site construction personnel: including production line and auxiliary equipment.

Workers in production line units have high labor intensity, bad working environment and high risk factor, especially in high gas mines or mines with water seepage danger. If there is a gas or water seepage accident, I don't think it is necessary to elaborate, and you can understand it.

Auxiliary units mainly provide production services for first-line units, which have less labor intensity and lower income compared with first-line units.

Coal mining industry is a high-risk industry, which is called "three risks into the well". Therefore, you must attend pre-job training, and you are not allowed to work in the well without training. The regulations are also for the safety of employees.

If you want to work in a coal mine, you must eat well and sleep well, and you need a relatively relaxed living atmosphere at home. Have a nice day at work.
