3、 are supplied with coal by two major mines based on Baganuur and Shivee-Ovoo.Baganuurs mine still supplies all power plants of Ulaanbaatar city as they were designed to use coal of this mine. During recent years,Shivee-Ovoo mine supplies coal to power plant No.4 located in Ulaanbaatar city,but quali
4、ties of coal for this mine still need more deep research,it standing certain problems.In future we are planning to supply not only native consumers by Shivee-Ovoo coal,also to construct larges power plant on the basis of this mine.So,more detailed research is faced us for Shivee-Ovoos mine coal.This
5、 report presents some results of the research that focused will widely use this coal in energy sector.

Coal mines of our country are evenly distributed in total territory of the country, comprising 12 basins with coal area divided to three zones. Today, over 300 mines are exposed, of which around
7、 80 are proven by prospective works1.According to preliminary assessment by prospective works coal resources of our country exceed 150 billions tons1 and coal resources of 22,3 billions tons are identified by preliminary and detailed prospective works. In energy sector 12,2billions tons of these res
8、ources can be used,of which 1billion tons are stone and coking coals, and 10.1 billion tons-brown coals of type ofB2 and B3.1The most known parts of the coal resources are stone and coking coal of Tavan Tolgoi mine, and stone coal of mines of Narii Sukhait, Khushoot, Nuurst Khotgor, Nalaikh,Sharyngo
9、l,brown coal from mines of Baganuur, Shivee-Ovoo,Uvdugkhudag, Tevshin Gobi, Tsaidamnuur, Khumultei, Ulaan-Ovoo, Tugrugnuur, etc. Among these mines, coal from stone coal mines has an age of carbon and permian period and brown-jurasic and cretaceous period, as well as of period of transition from high
10、 quality brown coal to stone coal. Research of coal resources of Mongolia and their location gives significant new geological materials for more substantial identification of geological formation, origin of coal ores, carbonization and so evaluation of detailed assessment of coal qualities and densi
11、ty was done fundamentally. The map of coal ores locations in Mongolia is shown below, prepared by Mr.D.Bat-Erdene. 1 Fig. 1. Map of locations of coal ores of Mongolia Coal consumption. Today in Mongolia, coal is used as main raw material in energetics, and production of power energy is highly depend
12、s on coal. Obviously, about 93% of generated total power energy is produced only from coal. Even though by beginning of 1990s coal mining was decreasing, but now it is growing steadily.

At power plants coal is crashe
14、d into smallest pieces then burned. Major technology applied at all power plants in Mongolia is flamed burning technology in volumetric furnace. So, technological burning mode, technical and economic basis is heavily dependent on what type of coal was designed to use for certain power plant. In othe
15、r words, when coal resources of mine, for whose coal certain power plant was designed to use, is exhausted or it due to technical problems mine would not be unable to supply the coal, technological operation of fuel supply system or steam generators of the plant will be broken, steam production will
16、 be reduced, causing negative impacts like slagging of radiation or convectivectionr. So that it may be reason of increasing number of breaks and stops, reducing efficiency ofteam generators, as well as the plant. Thats why more detailed research of thermotechnical parameters is needed, and identification of conditions for optimal use of coal from Baganuur and Shivee-Ovoo, supplying
