Vital role of instrumentation rock mechanics for manganese underground mines of Manganese Ore (India) Limited (MOIL) for introduction of Rapid Mining Technology (RMT)

摘要

Manganese Ore (India) Limited (MOIL), one of the pioneer in the manganese mines, operates 10 mines in Madhya Pradesh and Maharashtra states, out of which 6 mines are underground having access through inclines or by vertical shafts and 4 mines are opencast mines, making bed and dump mining activities for the production of high grade and medium grade of manganese ore. This paper deals with the gradual changes in the mining system by the introduction of various rapid mining technologies (RMT) in the underground mines in different phases.
