Distribution of Bauxite in India:-   bauxite ore Distribution of Bauxite in India:- Bauxite is the raw material for making aluminium. It is not a specific mineral but a rock consisting mainly of hydrated aluminium oxides. It is clay-like substance which is pinkish whitish or reddish in colour depending on the amount of iron content. Production and Distribution :-  The total reserves of bauxite in India are estimated at 27.40 crores tonnes. The major bauxite producing states in India are Orissa, Jharkhand, Gujrat, Maharashtra, Madhya Pradesh, Karnataka, Tamil Nadu, Uttar Pradesh and Goa in a descending order of importance. Orissa:-   Orissa is the largest producer of bauxite in the country and contributes about one-third of the total production. Kalahandi, Bolangir, Koraput, Sundargarh and Sambalpur are the main bauxite producing districts. Jharkhand:-  Jharkhand is the second largest producer of bauxite and produces about 22% of Indi...

Distribution Mica in India:- India  is a major producer of Mica in the world. It is the largest producer of sheet mica. According to British Geological Survey, the world’s largest deposit of mica is at Koderma district in the state of Jharkhand (India). About 95% of India’s mica is distributed in just three states of Jharkhand, Andhra Pradesh and Rajasthan 1. Jharkhand:-   Jharkhand has richest mica belt and accounts for 60% of India’s production in terms of value. Here, mica is found in a belt extending for about 150 km in length and 32 km in width from Gaya district of Bihar to Hazaribagh and Koderma districts of Jharkhand. Koderma is a well-known place for mica production in Jharkhand which produces more than 50% of the total mica production in India. 2. Andhra Pradesh:-  This is the second largest producer and accounts for nearly 25% of India’s mica. The main belt lies in Nellore district and is 97 kms long and 24-30 km wide. 3. Rajasthan:- ...

North East Coal Fields in India :- North East Coal Fields in India:- Workable coal fields seams occur in Assam and Meghalaya at three separate geological horizons, two of which belong to the Lower Eocene of Meghalaya and one in Oligocene of upper Assam. The rocks concerned belong to the Jaintia Formation in the first two regions and to the Barail Formation in the other. These coals, though of Tertiary age, are of a higher rank than many other young coals. They are advanced types of meta-lignite approaching bituminous coals in composition. The important coal-fields are located at:- Namphuk, Namchik, Makum, Jeypore, Nazira, Jhanzi and Disai of upper Assam; Longloi hill, Dissoma, Nambor, Doigrung, Charigaon, Cherrapunji, Mawlong, Lakadong and Salunga of the Khasi and Jaintia hills; Kharibari, Rongrengiri, Daranggiri, Dograng, Waimong, Tura hill and Siju of the Garo hills. The major coalfields of the north-eastern region are located at:- Makum (Reserve 235 ...

Information on Raniganj Coalfield:- The Raniganj coalfield, located in West Bengal, is situated at a distance of 125 km from Calcutta, the total area being about 1500 sq. km. the mining towns of Raniganj and Asansol are located within this coalfield. The Lower Gondwana rocks have been well preserved in this coalfield, the total thickness being about 3200 meters. The Barakar Measures containing yellowish sandstone, shale and coal seams, is overlaid with Ironstone Shale (365 meters thick), but devoid of coal seams. These are again overlain with the Raniganj Formation of rocks represented by fine-trained sandstone, shale and a few coal seams. The Barakar Measures, in this coalfield, contain 14 coal seams varying in thickness from 5 ft to 8 ft (24 meters). The seams have been named after the localities where they are found, with the result that the same seam is known by different names in different parts of the field. The coals of the Barakar Measures have relatively low mois...

Gondwana Coal:- The significant coal seams have been found in the rocks of the Damuda Group of Lower Gondwana age. Coal seams are found within the rocks of two formations, viz. the Lower or Barakar Coal Measures and the Upper or Raniganj Coal Measures. Geographically the rocks of the Barakar Formation are more extensive and the coal is superior in quality and more in quantity than the coals of the Raniganj Formation. The Lower Gondwana coalfields are scattered in the provinces of Andhra Pradesh, Assam, Orissa, West Bengal, Bihar Madhya Pradesh, Uttar Pradesh, Maharashtra and Sikkim. Although Upper Gondwana coals have been found in Gujarat (Ghuneru coalfield of Kachchh), Madhya Pradesh (Hiran river valley coalfield of Jabalpur district) and Maharashtra (Kota and Chikiala coalfields), but in the field of production, the Lower Gondwana coalfields are the most important. About 98 per cent of India’s total coal production comes from the Lower Gondwana coalfields. Of these coalf...

Trappers, Hurriers , and Hewers: Working in a Coal Mine:-                                       The Industrial Revolution really got its start in Great Britain during the second half of the  eighteenth century. A great many workers were needed in the burgeoning factories and in coal mines to provide the fuel for the factory machinery. Our ancestor came of age in the late 1700s, and would have been accustomed to working to help provide for his family – with a widowed mother and several siblings, there was no other option. Many jobs were available, although working conditions were appalling. Thomas Thomas’ early life, his employment – first as a shepherd, later as a coal miner – is mentioned in family held sources, but we have no details of how old he was when he took each of these jobs. Clearly, working in a coal mine would have been chosen out of necessity – it must have paid a ...

Coal mining in india  Coal mining in India   has a long history of commercial exploitation covering nearly 220 years starting in 1774 with John Sumner and Suetonius Grant Heatly of the East India Company in the Raniganj Coalfield along the Western bank of Damodar river. However, for about a century the growth of Indian coal mining remained sluggish for want of demand but the introduction of steam locomotives in 1853 gave a fillip to it. Within a short span, production rose to an annual average of 1 million metric tons (1.1 million short tons). India could produce 6.12 million metric tons (6.75 million short tons) per year by 1900 and 18 million metric tons (20 million short tons) per year by 1920. The production got a sudden boost from the First World War but went through a slump in the early thirties. The production reached a level of 29 million metric tons (32 million short tons)...

Mining machinery engineering:- Mining Machinery Engineering  is an interdisciplinary branch of  engineering  that applies the principles of  mechanical engineering ,  electrical engineering  and  mining engineering  for analysis, design, manufacturing and maintenance of  mining equipment . It includes study of various aspects of equipment used in  earthworks ,  mineral processing ,  bulk material handling ,  drilling  and  construction . History Surface mining equipment evolved at a high pace in the 20th century as the scale of mining grew up. In the first twenty years of the 1900s, steam power was largely replaced by  internal combustion engines  and  electric motors . Till the 1970s such equipment mainly used mechanical system and cables for power transmission after which they started to be replaced by  hydraulic drive system  for small machines. However, mechanical and c...
