There are two distinct types of caved stopes. In the first, the ore is broken
by caving induced by undercutting a block of ore. In the second, the ore itself
is removed by excavating a series of horizontal or inclined slices, while the
overlying capping is allowed to cave and fill the space occupied previously by
the ore. The first type comprises the caving methods of mining, while the
second comprises the top-slicing method.
