Mining - Phosphate
|
The major activity of RSMML is the mining of Rockphosphate ore. It operates one of the
largest and fully mechanised mines in the country at Jhamarkotra, 26 Kms.
from Udaipur
and Kanpur Group of Mines located 15 Kms. from Udaipur.
In India the economy
being predominantly based on agriculture,
the fertiliser production plays a pivotal role. Only about 35% to
40% of the requirement of raw material for phosphatic fertilser
production are being met through indigenous sources and the rest is
met through import in the form of rock phosphate, phosphoric acid &
direct fertilisers. In such a situation Jhamarkotra plays an
important role by contributing 98% of rock phosphate production of
India.
Rock Phosphate mines at Jhamarkotra & Kanpur
Group of Mines are complex deposits. Mining these rock phosphate
deposits is far more difficult than that in most parts of the world.
Despite the complexities of the deposit, excellent results have been
achieved by continuous innovations. With an annual rock handling of about
20 million tonnes, Jhamarkotra is probably the largest open cast mine in India
outside the steel and coal sectors. On technical fronts the problem
of ground water had affected the mining operations, until an
effective dewatering scheme was evolved and implemented. The
geometry of the ore body i.e thin and sharply dipping had resulted
in long and narrow pits with great depth extension, which involves
very high stripping ratio with high lead and lift for waste and
mineral. Despite all these problems Jhamarkotra project could
sustain the very difficult periods because of its commitment towards
scientific approach for exploitation of the deposit with planned
development of the pits.
The open pit mining method is being followed at
Jhamarkotra Mine for exploitation of the
mineral. The working levels are kept dry by continuous pumping of
ground water through tube-wells constructed on periphery of the pit
limit.
