series of deposits
of
associated minerals, such as, Colorado gold-molybdenum belt, US, Grant
uranium mineral Belt, New
Mexico Khetri

zinc-lead-silver belt, Rajasthan,
Sukinda
chromite belt, Orissa,

Block
is a
well-defined
area having
mineral concentration wholly
or partly of economic value, such as Broken Hill main, Australia, Bailadila
deposit-14,
Central Mochia, India. The
blocks in underground
mining are
subdivided to “Level”
(say: upper level, lower level, 500-700 and 300-500
mRL).
The levels are further split into “Stope” (say:West 301 stope,
North 101 stope,
Valley stope).
These terms
are locally convenient to use for attention and allocation
of work activities in mineral exploration and sequencing
mine production block.
