The first published, reference to the mining of coal in India dates back to the year 1774 in the Raniganj Coal Field. Coal mining methods can be broadly divided into two types viz. Surface Mining Methods and Underground Mining Method. The Indian coal industry is the world’s third largest in terms of production and fourth largest in terms of,Coal Exploration and Mining,two basic methods of extracting coal, i.e. surface mining and underground mining, are introduced. Firstly, two main methods—strip mining and open-pit mining—of surface mining are discussed. In underground mining, room and pillar, shortwall, and longwall mining methods are introduced.
