INTRODUCTION
Coal is the most important and abundant fossil fuel in India. It accounts for 55% of the country's
energy need and will continue to be the mainstay of its future energy supply. The country'sindustrial heritage was built upon indigenous coal. India now ranks 3rd amongst the coal
producing countries in the World. It provides most vital input for accelerating the growth of
Indian economy. The development of core infrastructure sectors like power, steel and cement aredependent on coal. The contribution of coal as fuel in power generation is about 65%.
The current per capita commercial primary energy consumption in India is well below that of
developed countries but driven by the rising population, expanding economy and a quest forimproved quality of life, energy usage in India is expected to rise exponentially. Considering the
limited reserve potentiality of petroleum & natural gas, eco-conservation restriction on hydelproject and geo-political perception of nuclear power, coal will continue to occupy centre-stage
of Indias energy scenario. Indian coal offers a unique eco-friendly fuel source to domestic
energy market for the next century and beyond. Hard coal deposit spread over 27 majorcoalfields, are mainly confined to eastern and south central parts of the country.

RATIONALE OF THE STUDY
Given the growing demand for coal arising from the economic and social needs of developingand developed countries alike, a multi stakeholder approach is needed. The challenge of
sustainable development is complex and multidimensional. It requires a positive, multifaceted
approach that employs all available means and explores all promising options. Coal has anessential role now and into the future in meeting this challenge. Energy is a fundamental driver
of economic development and contributor to peoples quality of life. It sustains the living
standards of developed countries to a high level of comfort and convenience and in the
developing world it leads people out of poverty. Access to electricity increases life expectancy,
reduces infant mortality, facilitates education and improves productivity. It provides a window tothe wider world. For India, coal is power, progress and prosperity as it constitutes the primesource of energy for this country. Coal is an essential resource for meeting the challenges facing
the modern world. It plays a major role in delivering electricity across the globe, is fundamental
in the creation of steel, concrete and provides energy for transport.
MEANING OF COAL
Coal is a combustible, sedimentary, organic rock which is composed mainly of carbon, hydrogen
and oxygen. It is formed from vegetation, which has been consolidated between other rock strataand altered by the combined effects of pressure and heat over millions of years to form coal
seams. Coal is a fossil fuel and is far more plentiful than oil or gas, with around 112 years of coal
remaining worldwide. Coal is a fossil fuel and is the altered remains of prehistoric vegetationthat originally accumulated in swamps and peat bogs. The energy we get from coal today comes
from the energy that plants absorbed from the sun millions of years ago. All living plants store
solar energy through a process known as photosynthesis. When plants die, this energy is usuallyreleased as the plants decay. Under conditions favorable to coal formation, the decaying process
is interrupted, preventing the release of the stored solar energy. The energy is locked into the
coal.

IMPORTANCE OF COAL
The importance of coal as a commercial fuel was first realized in the fourteen century but the
real impetus to the modern development of the coal mining Industry throughout the world came
by the application of coal to the smelting of iron in the eighteenth century and through theinvention of the stem engine. Since then, in modern industry, coal has been regarded untilrecently as the prime source of motive power. However, in the Indian context, it is still the prime
source of energy.Since coal has to continue to play a critical role in supporting Indias energy
plans for considerable time into the future, coal mining and coal usage should become more
environment friendly. India is currently among the top three fastest growing economies of theworld. As natural corollary India's energy needs too are fast expanding with its increased
industrialization and capacity addition in Power generation. This is where 'Coal' steps in. In India
coal is the critical input for major infrastructure industries like Power, Steel and Cement.
NATIONALIZATION OF THE COAL MINING
On account of the growing needs of the steel industry, a thrust had to be given on systematic
exploitation of coking coal reserves in Jharia Coalfield. Adequate capital investment to meet theburgeoning energy needs of the country was not forthcoming from the private coal mine owners.
Unscientific mining practices adopted by some of them and poor working conditions of labour in
some of the private coal mines became matters of concern for the Government. On account ofthese reasons, the Central Government took a decision to nationalize the private coal mines. The
nationalization was done in two phases, the first with the coking coal mines in 1971-72 and then
with the non-coking coal mines in 1973. In October, 1971, the Coking Coal Mines (EmergencyProvisions) Act, 1971 provided for taking over in public interest of the management of coking
coal mines and coke oven plants pending nationalization. This was followed by the Coking Coal
Mines (Nationalization) Act, 1972 under which the coking coal mines and the coke oven plantsother than those with the Tata Iron & Steel Company Limited and Indian Iron & Steel Company
Limited, were nationalized on 1.5.1972 and brought under the Bharat Coking Coal Limited
(BCCL), a new Central Government Undertaking. Another enactment, namely the Coal Mines(Taking Over of Management) Act, 1973, extended the right of the Government of India to take
over the management of the coking and non-coking coal mines in seven States including the
coking coal mines taken over in 1971. This was followed by the nationalization of all thesemines on 1.5.1973 with the enactment of the Coal Mines (Nationalization) Act, 1973 which now
is the piece of Central legislation determining the eligibility of coal mining in India. All non-
coking coal mines were nationalized in 1973 and placed under Coal Mines Authority of India. In1975, Eastern Coalfields Limited, a subsidiary of Coal India Limited, was formed. It took over
all the earlier private collieries in Raniganj Coalfield. Raniganj Coalfield covers an area of
443.50 square kilometers (171.24 sq mi) and has total coal reserves of 8,552.85 million tonnes.Eastern Coalfields puts the reserves at 29.72 billion tonnes. That makes it the second largestcoalfield in the country (in terms of reserves).

FACTORS WHICH LED UP TO NATIONALIZATION OF COAL INDUSTRY IN
INDIA
Nationalization of coal industry in India in the early seventies were a fall out of two related
events. In the first instance it was the oil price shock, which led the country to take up a closescrutiny of its energy options. A Fuel Policy Committee set up for this purpose identified coal asthe primary source of commercial energy. Secondly, the much needed investment needed for
growth of this sector was not forthcoming with coal mining largely in the hands of private sector.
The objectives of Nationalization as conceived by late Mohan Kumaramangalam were;
Conservation of the scarce coal resource, particularly coking coal, of the country by haltingwasteful, selective and slaughter mining, planned development of available coal resources,
improvement in safety standards, ensuring adequate investment for optimal utilization consistent
with growth needs and improving the quality of life of the work force.
HISTORY OF COAL MINING IN INDIA
The past India has a long history of commercial coal mining covering nearly 220 years starting
from 1774 by John Sumner andSuetonius Grant Heatly East India Company in the RaniganjCoalfield along the Western bank of river Damodar. 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 averageof 1 million tonne (mt) and India could produce 6.12 mts. per year by 1900 and 18 mts 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 mts. by 1942 and 30 mts. by 1946.After Independence, the Country embarked upon the 5-year development plans. At the beginning
of the 1st Plan, annual production went upto 33 mts. During the 1st Plan period itself, the need
for increasing coal production efficiently by systematic and scientific development of the coalindustry was being felt. Setting up of the National Coal Development Corporation (NCDC), a
Government of India Undertaking in 1956 with the collieries owned by the railways as its
nucleus was the first major step towards planned development of Indian Coal Industry. Alongwith the Singareni Collieries Company Ltd. (SCCL) which was already in operation since 1945
and which became a Government company under the control of Government of Andhra Pradesh
in 1956, India thus had two Government coal companies in the fifties. SCCL is now a jointundertaking of Government of Andhra Pradesh and Government of India sharing its equity in
51:49 ratios.
BARRIERS IN USING COAL
The barriers in using coal are as follows:
Limited supply (non-renewable resource)
Older plants (without emissions filters) generate large amounts of pollution
Generated smoke can cause health conditions such as emphysema

Sulphur dioxide and nitrogen emissions can bind to water creating acid rain
To dig up coal, we have to create mines which can be dangerous and not very nice to look at.
Transporting coal by lorry and train from the mine to the power station causes pollution.
Of all energy sources, burning coal releases the most greenhouse gases which may add to
global warming
Coal is a non-renewable source and will run out in about 100 years
Coal miners can be affected by black lung disease or pneumoconiosis and also emphysema if
they breathe in too much of the coal dust.
USE OF CLEAN COAL TECHNOLOGY
Clean coal technology is a collection of technologies being developed to mitigate theenvironmental impact ofcoal energy generation. When coal is used as a fuel source, the gaseousemissions generated by the thermal decomposition of the coal include sulphur dioxide, nitrogen
dioxide, carbon dioxide, and other chemical by products that vary depending of the type of the
coal being used. These emissions have been established to have a negative impact on theenvironment, contributing to acid rain and climate change. As a result, clean coal technologies
are being developed to remove or reduce pollutant emissions to the atmosphere. Some of the
techniques that would be used to accomplish this include chemically washing minerals and
impurities from the coal,gasification treating theflue gases withsteam to removesulphurdioxide, carbon capture and storage technologies to capture the carbon dioxide from theflue
gas and dewatering lower rank coals (brown coals) to improve thecalorific value,and thus the
efficiency of the conversion intoelectricity.
Clean coal technology usually addresses atmospheric problems resulting from burning coal.Historically, the primary focus was on sulphur dioxide and particulates, since it is the most
important gas in the causation ofacid rain.More recent focus has been on carbon dioxide (due to
its impact onglobal warming)as well as other pollutants. Concerns exist regarding the economicviability of these technologies and the timeframe of delivery, potentially high hidden economic
costs in terms of social and environmental damage, and the costs and viability of disposing of
removed carbon and other toxic matter.
One of the major disadvantages of using coal is that the combustion of coal is a major source of
greenhouse gases and other pollutants. Clean coal technology helps in reducing air emissions andother pollutants from power plants that use coal for power generation. Some companies are using
innovate techniques to clean coal and reduce emissions.

FOLLOWING ARE SOME OF THE ADVANCED TECHNOLOGIES OF COAL USAGE
SUPERCRITICAL AND ULTRA SUPERCRITICAL PULVERIZED COAL
COMBUSTION:This power plant type achieves high conversion efficiencies applying
supercritical steam conditions (higher pressure and temperature of the steam).
INTEGRATED GASIFICATION COMBINED CYCLE (IGCC): This technology appliescoal gasification with combustion of the coal gas in a gas turbine and the recovery of waste heat
in a boiler.
DIRECT COAL FIRED COMBINED CYCLE:Like the IGCC plant this technology is
applying a gas turbine and a steam turbine in a combined cycle. However, the coal is directlyburnt in the gas turbine without previous gasification.
UNDERGROUND COAL GASIFICATION:This is a process to gasify coal in-situ. In
addition to many other advantages, this process can avail the coal mines which are otherwise notaccessible.
COAL TO LIQUID (CTL): This is a process to convert coal to liquid fuels.
Coal Gasification technologies for coal with high ash is to be developed, and it should be
achieved in a decade or so. It will give a better and cleaner way of utilizing Indian coal.

HISTORY AND FORMATION OF COAL INDIA LIMITED
With dawn of the Indian independence a greater need for coal production was felt in the First
Five Year Plan. In 1951 the Working Party for the coal Industry was set up which included
representatives of coal industry, labour unions and government which suggested theamalgamation of small and fragmented producing units. Thus the idea for a nationalized unifiedcoal sector was born. Integrated overall planning in coal mining is a post-independence
phenomenon. National Coal Development Corporation was formed with 11 collieries with the
task of exploring new coalfields and expediting development of new coal mines.
FORMATION OF COAL INDIA LIMITED
With the Government's national energy policy the near total national control of coal mines in
India took place in two stages in 1970s. The Coking Coal Mines (Emergency Provisions) Act1971 was promulgated by Government on 16 October 1971 under which except the captive
mines of IISCO, TISCO, and DVC, the Government of India took over the management of all
226 coking coal mines and nationalised them on 1 May, 1972. Bharat Coking Coal Limited was
thus born. Further by promulgation of Coal Mines (Taking over of Management) Ordinance1973 on 31 January 1973 the Central Government took over the management of all 711 non-
coking coal mines. In the next phase of nationalization these mines were nationalized with effect
from 1 May 1973 and a public sector company named Coal Mines Authority Limited (CMAL)was formed to manage these non coking mines.
A formal holding company in the form of Coal India Limited was formed in November 1975 to
manage both the companies.
Coal India is a holding company with seven wholly owned coal producing subsidiary companies
and one mine planning & consultancy company. It encompasses the whole gamut ofidentification of coal reserves, detailed exploration followed by design and implementation and
optimizing operations for coal extraction in its mines. The producing companies are:
1. Eastern Coalfields Limited (ECL), Sanctoria, West Bengal
2. Bharat Coking Coal Limited (BCCL), Dhanbad, Jharkhand
3.
Central Coalfields Limited (CCL), Ranchi, Jharkhand
4. South Eastern Coalfields Limited (SECL), Bilaspur, Chattisgarh
5.
Western Coalfields Limited (WCL), Nagpur, Maharashtra
6. Northern Coalfields Limited (NCL), Singrauli, Madhya Pradesh
7. Mahanadi Coalfields Limtied (MCL), Sambalpur, Orissa
8. Coal India Africana Limitada, Mozambique

FINDINGS
Coal is the most abundant fuel resource in India. It is the prime source of energy and perhaps the
largest contributor to the industrial growth of the country. It is a crucial and enduring element in
a modern, balanced energy portfolio, providing a bridge to the future as an important low costand secure energy solution to sustainability challenges. Coal India Limited (CIL) is the largest
company in the world in terms of coal production. Coal continues to be the major source ofprimary commercial energy worldwide. Considering the limited reserve potentiality of petroleumand natural gas, eco-conservation restriction on hydel projects and geo-political perception of
nuclear power, coal will continue to occupy the centre stage of Indias energy scenario. Share of
coal in worlds energy consumption is 27%. The importance of coal in India can be gauged bythe fact that it supports about 54.5% of the commercial energy in the country. Coal has an
immensely valuable role in this respect, complementing other fuels and energy sources that are
generally more vulnerable to disruption.
DISCUSSION
Sustainable development is a broad goal, with three recognized pillars economic, social andenvironmental. Coal has a major future role to play in all three pillars. Coal makes a significanteconomic contribution to the global economy. For consumers, coal offers excellent value. In
most circumstances, it is cheaper per energy unit than other fuels, and as a result it has remained
the fuel of choice for electricity generation on a global basis.
Coal mining can and does provide a significant direct contribution to economic development at a
local level, particularly in the poorer parts of the world. Large-scale mines are often the biggest

source of income for rural communities. In addition to providing wages for local people, they are
also the source of much local economic and social infrastructure roads, transport, education,
water and communications. Coal is a major provider of the energy that is needed for
development and is not going to disappear. It is therefore important that clean coal technology
continues to improve, as will happen in the right policy environment. The challenge is to ensurethat advanced coal technology, along with other promising options including renewable, can be
fully explored as part of a more sustainable energy future. The coal industry recognizes the needto improve the environmental acceptability of its product. Furthering the development and
deployment of new coal utilization technology is a key priority area, and has an important policy
dimension. Coal producers are ready to work with others customers, suppliers, governments,international agencies, and civil society in pursuit of the common goal of sustainable
development.
CONCLUSION
Coal mining is a critical contributor to many economies and makes a substantial contribution forimproving the livelihoods of many. This is especially true in developing countries, allowing
them to address the challenges of poverty and development. Coal will play a major role
complementing renewable energy sources and will be a key source of energy to address gaps inwind and solar powered electricity. Coal, the most important fossil fuel in India is vital for its
energy security. While coal is poised for significant growth, it faces significant and mounting
social and environmental challenges. Even with its major hurdles, coal will remain a futuremainstay, a foundation and a fundament of our economy. Coal has a crucial role in meeting
current needs and is a resource bridge to meet future goals through the enhancement ofknowledge and technology. The challenge is to apply the right technology in the most efficient
and environmentally friendly way.
