Sinker training in Russia
A sinker is a mine worker who conducts preparatory mining operations at mining sites. The labor function is to dig holes. Tunnellers are in demand not only in the mining industry, but also in civil engineering for laying tunnels, installing new subway stations, and installing underground ventilation ducts.
Workers have to work in difficult conditions, so the specialty is considered male. Tunnellers drag and install reinforcing structures – this requires physical strength and endurance. The tasks of specialists may include drilling a hole with explosives, so knowledge of physics, mathematics, and the ability to make technical calculations using formulas are important.
Good tunnellers are attentive, responsible workers who are able to quickly respond to changes in the environment and make responsible decisions.
