Mines Safety Week Celebration at Kolihan Copper Mines


Metalliferous Mines Safety Week Celebration (Ajmer Region). Mines safety Week Celebrations at Kolihan Copper MInes. Kolihan Nagar PO, Khetri, Jhunjhunu Dist. Rajasthan India.

Geology: The rocks in the Khetri district belong to the Delhi super-group of pre-Cambrian age, which is sub divided into the Alwar and Ajabgarh groups. The older Alwar rocks are derived from predominantly arenaceous sediments, while the younger Ajabgarh rocks were originally of a more argillaceous nature. The transition between the two being gradational these formations are metamorphosed to quartzites, schists and phyllites. Some intrusive dolerite dykes are present, and veins of quartz and carbonates are common. The general strike of the formations is NNE-SSW with steep to gental dips towards the WNW. The economic mineralisation which gives rise to the orebodies is mainly localised in the upper parts of the amphibole-chlorite quartzite and garnet- amphibole-chlorite quartzite/schist. The mineralisation occurs in the form of veins, veinlets, stringers and disseminations ( rarely massive), oriented in general parallel to the foliation plane. In Khetri mines there are two distinct ore lodes, namely the Madhan (or foot wall ) lode and the Kudhan (or hanging wall) lode. The Madhan lode is fairly persistant, containing a number of ore lenses. The Kudhan lode , on the other hand, is narrower, poorer in copper, and the lenses are less persistant. It is well formed in the central part of the mine. The Banwas copper deposit ( Banwas Block of Kheter Copper Mine ) forms the north extension of Khetri Block and constitutes the segment extending over a strike length of the deposit in 1.20 Km. The entire area is peneplained and shows flat topography having average RL around 350 M. The rocks are covered by thick alluvium and sandy soil. As the area is covered by soil and alluvium, the geological sequence of the rocks is established mostly by sub-surface geo data obtained through diamond drilling, The strike of the rocks varies from N 52° E – S 52° W to N 68° E  -S 68° W. The dip varies from 50° to 70° due North-West. An Introduction to Malanjkhand Ariel View of Malanjkhand General View of Malanjkhand Copper Mines Malanjkhand Township Quarters Mechanized OpenCast Copper Mining My Last Working Day on 19.09.2009 at Hindustan Copper Limited Photo from Malanjkhand Copper Project Plantation at Malanjkhand Copper Project Wikimapia - Training Centre Malanjkhand Wikimapia Malanjkhand Copper Mines
