Abstract :
Knowledge of the petrographic and physical characteristics of a coal has a broad application in processing of coal. Petrographic data are fundamental to the understanding of the behavior of coals during mining, washing, blending and coking. The visible bands in coals called lithotypes consist of four main groups namely, vitrain, kelarin, durain and fusain. The main lithotypes of coals are macerales that can be identified based on their texture and the degree of relative reflectance. In this research, coals from five different mines (i.e., Hashoni, Hamkar, Komsar, Eastern Darbid Khoon and main Pabedena) from Kerman area were studied by the reflected microscope. The samples of these mines were taken from the feed to the Zarand coal preparation plant sent by the mines in question. After the preparation of polished samples, the amount of coal macerals for each mine was determined. The results revealed that Eastern Darbid Khoon mine had the highest level of vitranite and the lowest amount of fusinite that render the best coking properties for this type of coal. From the coking properties aspects, main Pabedena mine showed the poorest quality.
