mine shaft
Mineshafts
Mineshafts are tunnels bored deep into the ground in order to extract minerals and ores. This can include precious metals, coal, gemstones, and other minerals. Mineshafts are a common feature of abandoned mines and were once used extensively to extract ore without the need for expensiv......
deep heat mine ventilation
Deep Mine Ventilation
Most deep mines must use some form of artificial ventilation to ensure that air in the mine is breathable. Ventilation also ensures that toxic gases, such as methane and carbon monoxide, which can cause serious health problems and even death, are not allowed to build up to d......
