Miners operate mining machines moving the self-propelled machines into positions. Thiey extract coal, metal and non-metal ores, stone or sand from the walls of mines, called the mine face. Those materials are then placed in shuttle cars or onto conveyor belts. They install ventilation curtains and pipes to ensure air quality, and check for methane gas to provide safe conditions. They monitor support systems to ensure stability in the mine and work areas.
