In the Panadhro village, in the district of Kutchchh is the Power Station, which utilises lignite type of coal. Lignite is a brown colour coal. Panadhro village has coal mines, which directly supplies coal to the power station. At present the power station has four units. 

Haematite is a reddish-black mineral and an important ore of iron. It has a high iron content of 70 percent. It can be found in areas of volcanic activity or hot springs. Much hematite occurs in a soft, fine-grained, earthy form called red ochre.

Coal is an inflammable organic substance, composed mainly of hydrocarbons, found in the form of sedimentary rocks and capable of being used as fuel to supply heat or light or both. It is formed when sub merged vegetation remains under great pressure for a considerably long time. 

Bituminous coal or black coal and Lignite coal are relatively soft. Bituminous is a higher quality than lignite coal but of poorer quality than anthracite.

Anthracite is a best quality coal. Its carbon content is 90% to 95%. Its burns slowly and great heat, with very little smoke.

Lignite is a lower grade coal and contains about 40% to 60% carbon. It has low heating power and emits smoke. Its colour varies from dark to black brown. 

Peat is the first stage of transformation of wood into coal and contains 30% to 45% carbon, sufficient volatile matter and lot of moisture. Its heating capacity is low and normally used as domestic fuel. 

Peat is the first stage of transformation of wood into coal and contains less than 40% to 55% carbon, sufficient volatile matter and lot of moisture. Its heating capacity is low and generally used as domestic fuel.
