DEF

Stoping in which no regular artificial method of support is employed, although occasional props or cribs may be used to hold local patches of insecure ground. The walls and roof are self-supporting, and open stopes can be used only where the ore and wall rocks are firm. The simplest open stopes are those in which the entire ore body is removed from wall to wall without leaving any pillars.
