Abstract

Erdenebulag coal deposit belongs to South Gobi coal-bearing basin. Coal is hosted in Middle Permian Tavantolgoi formation. As the results of exploration program, four coal seams with the thickness ranging from 0.95 m to 12.7 m in the Tulga area and five coal seams with the thickness ranging from 2.1 m to 21m in the Baga-Argalant area have been discoeverd so far. Coal seams in Tulga area form monoclinic structure, whereas that in Baga-Argalant area form synclinal structure. Coal qailities of the Tulga and Baga-Argalant areas of Erdenebulag deposit are as follow: moisture is 3.4-6.0%, ash is 15.2-19.3%, volatile matter is 29.1-40.0%, calorific value is 6043-
6671 kcal/kg and total sulfur is 0.7-0.9%. Petrographycla studies suggest that coal has three microlithitypes – duroclarite, clarodurite and durite with low mineral contents. Vitrinite and inertinite contents are 38.5-91% and 5.3-51.4%, respectively. Liptinte content ranges from 2% to 12 %.
