Underground
Mining Methods In mining, a method of extraction
is employed which will yield the largest net return. The
method employed must be safe and must also permit optimum extraction under the particular geological conditions
encountered. The best method of stoping depends on:
- the geological characteristics that determine the area
of back or walls that will be self-supporting during the removal of ore
- the nature and size of supports required
- and the support required for permanent openings to prevent
subsidence.
