| Underground mines are established in areas with promising ore deposits. The shaft is the primary vertical channel through which people and ore are transported in and out of the mine. The miners’ elevator is called a cage, and the ore reaches the surface via a car called a skip. A ventilation system near the main shaft ensures that miners receive fresh air and prevents the accumulation of dangerous gases. A system of crosscuts connects the ore body to the main shaft at several levels, and these levels are, in turn, connected by openings called raises. Stopes are the chambers where the ore is broken and mined. |
