GLOBAL COAL BASED POWER GENERATION SCENARIO • Coal is one of the world‘s most important sources of energy, fuelling almost 40% of electricity worldwide. In many countries, this figure is much higher: • Poland relies on coal for over 94% of its electricity; • South Africa for 92%; • China for 77%; • Australia for 76%. • Coal has been the world‘s fastest growing energy source in recent years — faster than gas, oil, nuclear, hydro and renewable sources. by Tariq Sarwar & Engr. Saima 9

THAR COAL FIELD • The Thar coalfield is located in Thar Desert, Tharparkar District of Sindh province in Pakistan. The deposits - 6th largest coal reserves in the world, were discovered in 1991 by Geological Survey of Pakistan (GSP) and the United State Agency for International Development. • Pakistan has emerged as one of the leading countries seventh in the list of top 20 countries of the world after the discovery of huge lignite coal resources in Sindh. The economic coal deposits of Pakistan are restricted to Paleocene and Eocene rock sequences. It is one of the world’s largest lignite deposits discovered by GSP in 90’s, spread over more than 9,000 km2. comprise around 175 billion tones sufficient to meet the country’s fuel requirements for centuries. by Tariq Sarwar & Engr. Saima 10

Background Primer on Coal: • Coal consists of the fossilized remains of ancient plant life that have been transformed through metamorphosis into carbon-rich mineral deposits. Coal mineral classification considers type, rank, and grade. The plant life that coal originated from determines its type, and the degree of metamorphosis determines its rank, grade, and the amount of inorganic mineral matter present. Qualities such as moisture, carbon, sulfur, and ash content contribute to a coal’s heating value as a fuel (measured in British thermal units Btu. by Tariq Sarwar & Engr. Saima 12

Classification of Coal by Tariq Sarwar & Engr. Saima 13

The Coal Cycle • After being mined, coal goes through a cleaning prep facility, where it is cleaned and separated by grades. Cleaning upgrades the quality of the coal by removing some of the impurities such as rock, clay, and other ashproducing material. Utilities burn pulverized coal to produce high-pressure steam that powers an electric generator. As coal is burned, emissions are produced that contain sulfur dioxide, nitrogen oxides, carbon dioxide, particulate matter, ash, and mercury. A discussion of coal combustion emissions is found. by Tariq Sarwar & Engr. Saima 14

MINING METHODS UNDERGROUND MINING There are two main methods of underground mining: A- room-and-pillar mining B- long wall mining. • The main advantage of room–and-pillar mining over longwall mining is that it allows coal production to start much more quickly, using mobile machinery that costs under $5 million (longwall mining machinery can cost $50 million). The choice of mining technique is site specific but always based on economic considerations; differences even within a single mine can lead to both methods being used. 2- SURFACE MINING or open cut mining • Surface mining – also known as opencast or opencut mining – is only economic when the coal seam is near the surface. This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited – 90% or more of the coal can be recovered. 1- by Tariq Sarwar & Engr. Saima 17

ROOM AND PILLAR MINING In room-and-pillar mining, coal deposits are mined by cutting a network of ‘rooms’ into the coal seam and leaving behind ‘pillars’ of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam – although this coal can sometimes be recovered at a later stage. This can be achieved in what is known as ‘retreat mining’, where coal is mined from the pillars as workers retreat. The roof is then allowed to collapse and the mine is abandoned. by Tariq Sarwar & Engr. Saima 18

by Tariq Sarwar & Engr. Saima 19

LONG WALL MINING • Long wall mining involves the full extraction of coal from a section of the seam or ‘face’ using mechanical shearers. A long wall face requires careful planning to ensure favorable geology exists throughout the section before development work begins. The coal ‘face’ can vary in length from 100-350m. Self advancing, hydraulically-powered supports temporarily hold up the roof while coal is extracted. When coal has been extracted from the area, the roof is allowed to collapse. Over 75% of the coal in the deposit can be extracted from panels of coal that can extend 3km through the coal seam. by Tariq Sarwar & Engr. Saima 20

Efforts & Achievements of Government of Sindh for Thar • The road map for the development of Pakistan coal reserve‘ needs to be built on recognizing coal as an integral part of future energy mix and devising strategy to develop it as ‗core resource‘ in energy mix. This approach requires an enabling environment, which can be achieved by investing exclusively in building physical and institutional infrastructure. The government of Sindh has taken many initiatives and following benchmarks have been achieved to provide enabling environment:- by Tariq Sarwar & Engr. Saima 28

i. Thar Coal Projects declared as Projects of National Importance and development of Thar coal as a matter of national security. ii. Creation of one window organization viz. TCEB having both federal and provincial governments sit together to facilitate collective decisions making regarding Thar Coal Development. iii. Provision of Fiscal Incentive Package for attracting FDI to Thar-Thar Coal & Energy Board and ECC approved a comprehensive Incentive package. iv. There is no customs duty on Coal Mining Machinery and Equipment and 20.5% IRR has been guaranteed by ECC to those projects, which achieve financial close before December 2014. v. Promotion of Joint Venture Partnership in Coal Development has been introduced and bold initiative of entering into a unique joint venture agreement, with one of the largest industrial groups of the country, viz Engro Group for Thar Coal Development is one of the key proactive steps taken by the Government of Sindh. by Tariq Sarwar & Engr. Saima 29

vi. Detailed exploration and geological assessment of 12 Blocks measuring 1483 Sq Km with total lignite resources of more than 20 billion tons sufficient to meet power requirement of the country for next 100 years. vii. Construction of Thar Airport to facilitate investors-Thar Coalfield is located 410 km away from nearest airport. Air port Construction works are in full swing and by December 2013 Thar Airport will be available to facilitate travel of local and foreign investors to coalfields and for transportation of light machinery and equipment. viii. Improvement of Road Network leading to Thar Coal field for movement of heavy Mining Machinery- Government of Sindh has initiated the project for Improvement & Widening of Road Network from Seaport Karachi to Thar Coalfield Area via Thatta, Badin, up to Wango (Phase-I 200 KM) and Wango More to Thar Coalfield Area (Phase-II 134.86 km). The Project will be completed in 2014. by Tariq Sarwar & Engr. Saima 30

ix. Construction and successful operation of Reverse Osmosis Plants in Thar for supply of potable water to people of Thar Region-the Government of Sindh as part of infrastructure development undertook the task for providing long-term and economical solution of potable water to the inhabitants living near coalfield area of Thar Desert. Brackish/saline groundwater converted into potable water through sophisticated Reverse Osmosis (water desalination) technology. Government of Sindh has installed 110 RO plants in Tharparkar, Thatta, Badin, Umarkot areas catering the population of approx 850000 in four districts. x. Construction of Thar Lodge-Keeping in view the requirements of decent accommodation for investors near Coal Mining site at Islamkot, the Government of Sindh has constructed a high standard accommodation facility by the name of Thar Lodge. Thar Lodge is consisting of five chalets each having two bed rooms and a main building having 10 rooms, drawing/dining hall, kitchen, dormitories, lobby, porch, mosque, garage and servant quarters. by Tariq Sarwar & Engr.

How is Coal Converted to Electricity? by Tariq Sarwar & Engr. Saima 35

Lignite Based Power Generation in India • Lignite mining all over the world is being carried out under complex hydro geological and geotechnical environments causing a range of problems affecting the production method and utilization of run-off mine coal. There are many practical examples of large lignite deposit developments in the world. Neyvelli lignite deposit in South India is among those with similar geological conditions at Thar Pakistan. There are no technical difficulties in developing this lignite field and producing lignite from a deep place. • The lignite seam in Neyvelli lignite deposit was first exposed in August 1961, and regular mining of lignite commenced in May 1962. Neyvelli Lignite Corporation Ltd. is producing approximately 2.4 million tons of lignite from four open cast pits, and feeds the lignite to mine-mouth power plants (Total capacity 2740 MW). by Tariq Sarwar & Engr. Saima 36

Neyveli Lignite Corporation Limited India • Neyveli Lignite Corporation Limited (NLC) is a governmentowned lignite mining and power generating company in India. NLC operates the largest open-pit lignite mines in India, presently mining 24 MT of lignite and has an installed capacity of 2,740 MW of electricity. It also supplies a large quantity of sweet water to Chennai from the artesian aquifers in the lignite mines. On 11 April 2011, it joined the elite group of Navratna Companies. In 1956 NLC was formed as a Corporate body. • • Founded1956 • HeadquartersChennai, India • Key people Shri.
