INTRODUCTION Coal is a black or brown rock that can be
ignited and burned to produce energy in the form of heat.

First Indian mining operations begun in 1774.
Development of steam engine in 1850’s spurred coal demand.
World War I created another surge in demand.
National Coal Development Corporation (NCDC) – 1956 formed.
Steel industry growth in 1950’s and 1960’s sent coal demand to all time highs.

SURFACE MINING
Surface mining is done by removing (stripping) surface vegetation, dirt, and if necessary, layers of bedrock in order to reach buried ore deposits.

UNDERGROUNG MINING
Underground mining consists of digging tunnels or shafts into the earth to reach buried ore deposits, Underground modes of access include drift, slope, and shaft mining.

Future of Coal in India
Rapid population growth and skyrocketing demand for energy.
70% of coal consumption expected to be in electric power sector.
In 2003, coal-fired power plants consumed 5.0 quadrillion Btu of coal, representing 69% of India’s total coal demand.
Coal-fired generating capacity projected to increase from 67 GW in 2003 to 161 GW in 2030.
