It has been estimated that about 400 million tones of natural coke (Jhana) exists in the Jharia coalfield. Apart from difficulties of mining this hard material, its utilization is the biggest stumbling block in its winning. The paper makes a study of the different properties of natural coke from different sources of the Jharia coalfield with a view to studying the potentialities of its use. Some of the important observations are – the very low melting point of the ash and very good combustion characteristics when the material is crushed to a particular size. The first property suggests the possibility of its utilization in furnaces where a molten ash is desirable for ease of removal and the second property suggests its possible utilization as a domestic fuel. The formation of the natural coke must have taken place at a temperature of above 600ºC but not exceeding 900ºC. the composition of ash indicates reaction of the intrusive material with coal during the formation of natural coke.
