The diploma thesis provides an overview of history of exploration, geological and stratigraphical settings and coal mining of the Karaganda and Ekibastuz basins in NE Kazakhstan; the two most important hard coal deposits of the country. Although the coal- bearing strata of both basins are identical (visé), the mining conditions and quality of coal significantly differ. The seams No. 1, 2 and 3 of the Bogatyr Opencast (Ekibastuz Basin) are merged into a single coal-bearing horizon reaching a cumulative thickness between 150 and 170 meters located in shallow depth. On the opposite, seams of the Saranska Mine (K10, K12 and K18) in the Karaganda Basin are usually only few metres (locally up to 5 m) thick and in most part of the coalfield are situated in depth up to several hundred metres. Seam and overburden thicknesses affect the mining methods. In the Karaganda Basin coal is extracted in deep mines whereas in the Ekibastuz Basin in huge opencast mines. To provide a comparison of extracted coal, samples taken from the Bogatyr Opencast (Ekibastuz Basin) and from the Saranska Mine (Karaganda Basin) were analysed for their petrographic (maceral) composition and chemical and technological properties. The results show that in the seams Nos. 2, 3v, 3G, 3D, 3E, 3Z and 3Z from the Bogatyr Opencast and seam...
