The table below lists the mines and the type of cr,al 1111_, lignite.

Black coal is the oldest and lignite the youngest All known deposits of black and brown coal and lignite are included above, including deposits not yet exploited. Considering that Slovenian -oal deposits are not inexhaustible and that coal has become a raw material, Slovenia, must aim to utilize the entire potential heating capacity of the coal. If Slovenia continues to exploit coal at the same rate as it is doing today, the black and brown coal deposits will last for only two generations, whereas the lignite deposits will last some tens of generations.

It was.aatimated in 1939 that deposits in Yugoslavia amounted to i8 x 10 tons or 1 1,400 of world deposits. Large depos- its of lignite and brown cop' have been discovered since the liberation. With the acquisition of the liberated districts, Yugoslavia acq?"ired the Rasa and Ilirska Bistrica mires. The'coal deposits in Slovenia are 1/18 of the estimated deposits in Yugoslavia. The population. of Yugoslavia is 1/137 or 0.75 percent of the total world ,opulation (2.4 billion). World deposits amount to 2,900 tons of coal per capita; deposits in Yugoslavia amount to ouly 300 tons per capita. This figure is much lower for Slovenia. If lignite is ir:luded, however, the figure is 900 tons per capita. Much'of the heat potential of coal used in furnaces, stoves, and ranges is wasted. Locomotives utilize only 7 percent of the total caloric potential of coal; steam boilers, 65 percent; gas generators, 85 percent; and ranges and stoves, 12 percent. These losses cannot be remedied very much, as steam boilers, locomotives, ranges, and stoves would have to be redesigned to raise their effi- ciency factor. Coal deposits are dwindling daily., Coal has become a raw material whose importance as a fuel is diminishing. Therefore, serious thought must be given to i ?ise. It is high tics ti-a- Yugoslavia used coal as fuel only when it is impossible to use other f.:el, Poorer grades of coal should be used for fuel, and new heating installations snou:d to con, tructed to use poorer grades. Much of the caloric ?._lutt of coal burned in furnaces and other heating installations is lost on the surface of the boilers or steam pipes. Consequently, all such surfaces not serving for heating should 7e can=fully insulated. Exper- ience has shown that 1,200 :.glories/per kilogram per hour are lost on one square meter of uninsulated surface where the temperature is 100 degrees centigrade higher than the surrounding air, This loss increases as the temperature increases. If the steam conductor is Nell in_ulated. the loss de-rear- to 350 calories per kilogram per heir per square meter, by uscog insulating flanges and valves the loss is further reduced to 220 calories per kilogram per hour per square motor. Up to now Yugoslavia has planned the use of coal in accordance with so- called..production and steam norms. Since every planner wants to be dependable and fears inferior quality and irregular delivery, he requisitions larger quanti- ties of coal from year to year even though production remains stationary. As a result, mines produce coal in excess of current needs. It is stored in unsuit- able warehouses, or even in the open, where it deteriorates in caloric value and often even in appearance. A second result is that too much coal is fed into the grate so that it falls through unburned into the slag, Planning should take into account the maximum capacity of the grate of each boiler, taking into account both the surface area of the ;rate an, the heating surface .? the boiler. The equation B:k2H should serve to determine the amount of coal to be used. B is the. amount of coal in kilograms with regard to caloric value and quality which is stipulated for a particular grate; k2 is the amount of coal in kilograms which burns in one hour on one square meter, approximately 8.1 to 11 kilograms (an average of 9.5); and H is the heating surface of the boiler in square meters.
