Summary: Coal covers 80% reserves of the world energy potential.
There areintentions of ever bigger utilization of this resource but alsoof
the necessity to solve the problems of fuel-combustion puretechnology. In
that context, underground gasification of coal isespecially important. The
report discusses instaled energypotential in Croatia and the possibilities
of activating the coaldeposits "Poljanica Sušobreg" (Croatia) and
"Kongora"(Herceg-Bosna).

Summary: Great coal reserves are proven in Bosnia and
Herzegovina.Significant power plants and surface coal mines are
constructed,partly invested by Republica Croatia. Difficulties in
billateralrelations are present, specially after beginning of the
war.Mutual interest in energy field can be found in future. Coaldeposites
situated near frontier line of South Croatia (Livno,Tomislavgrad, Bugojno)
are specially interesting for Croatiawhere is now deficiency of electrical
energy. With this paper wewould like to point out the possibillities
authorities to beconsidered by creating future state energy policy.

Summary: Coal mining tradition in Istria is 180 years old. The
onlyexploitable mine there is the "Tupljak" pit where there arebalanced
reserves. A part of the pit is open and completelyprepared for excavation
(section II). Current production amountsto 120000 t yearly and it is
planned to keep in such by 2000,after which the pit closing down is
supposed. The nextexploitation field (section III) is reached by mining
activities.The possibility of exploiting these reserves as well is
pointedout, what may prolong the mine life time till 2007, butjustification
of these tendences needs to be proved yet bytechnical-economic analysis.

Summary: During sixty years of researchs conducted on various ranks
ofcoals and various formation conditions, the method of undergroundcoal
gasification became technically feasible. Control and methodconduction
remained the biggest problem. By future improvement,low recovery ratio of
resource will be closer to recovery ratioof coal power plant. Underground
coal gasification enlarge energybase by transforming unpayable resources
into energy reserves.
In Croatia, more then 300 million tons of coal reserves, mainlylignite are
balanced. The beds of lignite have sufficientthickness, large regularity in
strike, they are situated intectonically calm areas, which makes suitable
surroundings forconduction of gasification.

Summary: The explosion of lignite coal dust caused death of whole
shift (180 miners) in the pit "Dobrnja" of the Kreka mine (Tuzla, Bosnia
and Herzegowina). Analyzing several former coal-dust inflammations caused
in the same way (desruction of the steel suport by mudcapping) under
similar conditions but different occurence intensity. a possible succession
of incidents from the beginning of inflammation to its transformation into
explosion is discussed. Namely, local occurences were proved only with the
traces of burning (5 cases), the case of a large-scale inflammation with
injuries of 20 miners (30th December 1990) and the explosion itself (26th
August 1990) as a final succesion of incidents.
