Stamp Information : I am reproducing the same matter as in the writeup
Kolar Gold Fields in the State of Karnataka are reported to
have been mined for gold during the last 2000 years or so. The gold lodes of
Kolar Gold Fields lie in a narrow bond of rocks of Dharwar Series. The
systematic mining for gold in this area during modern times was started by an
English mining firm, John Taylor & Sons in 1880. The mines were taken over
by the Government of Mysore in 1956 and by the Government of India in 1962. The
provision of railway connection in 1894 and availibility of electric power in
1902 from the first hydel power station in Asia at Sivasamudram played a key
role in rapid development of the mines. These are some of the depest mines in
the world, the deepest point being 3.2 Km below surface. Inclined and vertical
shafts have been sunk either along the reef or across the country rock. The
length of excavations underground in the form of tunnels, shafts, etc. total
about 1000 Kms. The gold-bearing ore is excavated in a carefully systamised
sequence and the shafts and tunnels are supported by steel arches lagged with
timber to ensure safety of mine workers. In view of very high stresses
ancountered in deep mines, excavations are also supported by granite, concrete,
timber amd mill-tailing fill as a safety measure. During the early period of
mining, the tenor of gold averaged about 40 grammes per tonne. During the past
century, approximately 46 million tonnes of gold-bearing ore has been extracted
yielding about 784 tonnes of gold. The present tenor of gold is about 5 grammes
per tonne. The present management, Bharat Gold Mines Ltd., a Government of
India undertaking, attaches considerable importance to measures providing safe
and hygienic working conditions. Instrumentation of working areas to monitor
possible violent rock failures, adequate ventilation, effective dust
suppression and fire fighting equpment are some of the measures which play
major roles in this sphere. Regular radilogical examination of workers and
sampling of underground ore for toxic dust are important industrial hygiene
measures undertaken by the management. At present about 12000 employees of
various categories are on the rolls. Being a labour intensive industry, massive
efforts are made to educate the workers in accident prevention. High priority
is also given to the welfare of the employees.
