Lignite possibilities of Ereğli-Ayranci-Karapinar (Konya) region and determinaton of its economical value

This study includes drilling - geophysical studies and chemical analysis of lignite of Konya-Karapınar Basin which is started to study in 2007 by MTA within ?Central and East Anatolian Lignite Project? around Karapınar-(Konya), Ayrancı (Karaman). Lignite seams in the region are included Pliocene Hotamış Formation (Nh) which is deposited lacustrine and fluvial enviroment and is composed of siltstone, claystone, sandstone, mudstone, clay, fossiliferous clay and lignite. Lignites in Hotamış Formation are light brown, brown, black colored, moderate hard and brittle,and are shown thin,moderate, thick beddings.Full analysis values according to obtained from the original coal, coal consist of 47.07% water, 20.05% ash, 23.33% volatile substance, 9.55% fixed carbon, 1.54%flammable sulfur, 1.29% sulfur in ash and its low heating value is 1343 Kcal/kg.The coal field were characterized with izohips maps which obtained from full analysis results. Drillings in the field shown that geological spreading boundary of coal which is shown horizontal and close to the horizontal bedding, is about 80 km2 area. Also proved reserve of coal is 1.280.000 tonnes.
