Summary: The trial cultivation of mushrooms (Agaricus bisporus) in
one ofthe dead faces of the "Krš" pit of the Dalmatian bauxite minesObrovac
proved, that an optimal yield can be attained with thedomestic mycelium.
The decision has been brought to go on withinvestments into equipment for
new growing-site locations inunderground workings of the mine. In order to
cultivatehigh-quality mushrooms, the ventilation of growing sites has
beenparticularly considered. Compressive separate ventilation ofgrowing
fields has been applied using the main and the returnventilation pipeline,
with the air current regulation accordingto the growing stage.

Summary: The studies of turbulent flows in round pipes resulted in
manyhydraulic formulas up to these days, wich can also serve inprojecting
to calculate the resistance to the air flow inunderground openings. The
report discusses the way ofestablishing the hydraulic friction factor of
untimberedunderground workings when the vakue of equivalent roughness
isobtained by measuring the ventilation parameters in a similarworking of
some other mine. A double reticular nomogram has beenconstructed for the
fast determination of friction coefficientfrom the known roughness of an
underground working.

Summary: Exploitation of bauxite in region of Dalmatia has tradition
ofmore than 50 years. The biggest underground mine of the bauxitebearing
area was developed in deposit Ćukovac-Grižinica withproved workable
reserves of 1.200.000 t. Yearly output in 1990.was 100.000 t. Production in
this mine started 1987, and sublevelcaving method was used.
Coefficient of extraction in the parts with weak rocks is low,and
unsufficient security in the conditions with firm roof.Therefore
investigation of improvement of mining method wascarrying on to coinside
characteristics of rocks, and miningmethods. Folowing methods were
selected: sublevel caving(actually retreat stoping), sublevel stoping and
sublevel cavingwith bauxite protection layer.

Summary: The paper deals with the procedure for numerical solution
of thesoil consolidation problem.
The theoretical background of the procedure is given within theframework of
Biot's theory of consolidation. Unlike the usualapproach, the displacement
of the soil skeleton and thedisplacement of the pore fluid relative to the
skeleton aredefined as the main field variables. Besides, a
generalstress-strain constitutive equation for soil skeleton is allowedfor.
Finite element formulation is given by means of Galerkin methodusing the
"weak formulation". Time discretization includesexplicit and implicit
schemes.

in crossing support of drifts and crosscuts tillnow, where it came in about
6% cases to the breakage of the framesupport and to crossing ceiling
caving. On the basis of suchbiggest caving, the estimate and dimensioning
of critical supportelements (runner and bar) were performed. The
possibility of thesupporting by bolting and stell plate was also
considered. Forthe central part of the crosscut the use of bolts was
assumed,which are fixed in the up-face, and for the rest of crossing
theexpansion shell anchors. For the latter, the estimate foranchoring
elements was elaborated. Technical, safety and economicadvantage of the
bolts support is proved when compared with theframe support.

Summary: Underground exploitation of bauxite with weak roof rocks
resultsusually in very low extraction of ore due to technologicalreasons
which do not allow ore dilution. Most frequent, weakroof are marl,
overconsolidated stiff fissured clay, chrushedlimestone and conglomerates.
A successful exploitation in suchconditions depends on the selection and
adaptation of the mininigmethod.
The room and pillar method is the most used in mining of tabulardeposits.
Various modifications of sublevel stoping and sublevelcaving methods are
used in mining of irregular thick deposits.Current investigations with rock
bolts in weak rock made itpossible that the block method and some other
methods could bedeveloped and adapted for use.

Summary: MINIERA DI SOVIGNACCO - A WORLD IMPORTANT MINERALOGICAL
ANDMINING SITE IN ISTRIA (CROATIA)
1566 is the year of the first confirmed mention of the worldsoldest bauxite
mining. The first bauxite mines was opened some300 years earlier than the
mine at Villeveyrac in France whichopened 1873 and up to now was considered
as the oldest in theworld. From the middle of the 16th century and
especiallyintensively to the end of 18th and partly during the 19th
centuryin the valley of the river Mirna /Quieto in Northern Istria
greenpyritic bauxite for winning of alum and vitriol was mined. In
theregion now called MINJERA - after the MINIERA DI ALLUME EVETRIOLO DI S.
PIETRO a SOVIGNACCO - the mined bauxite wasmanufactured by methods which
the then owner Pietro Turini indetail described in a treatise published
1808 in Venice.
So the ore from the MINJERA is important not only historicallybut is
significiant in a scientific sense too: the bauxite ofthis region was the
first of which psyhical and chemicalcharacteristics have been completently
presented and published.Therefore the scientific priority has to be given
to the pyriticbauxite from the Istrian Mirna vally and not to the bauxite
fromLe Baux in France, the denominator of that ore.

Summary: In the paper results of many years of archival and
fieldinvestigations in the histiru of bauxite mining of the threeauthors
are presented. It was established that in Istria in thevalley of the river
Mirna beneath the Castle of Sovinjak bauxitewas exploited already 400 years
ago, and that 1808 about this orethe first scientific account was
published. Accordingly, thestatements in the professional literature that
the first bauxitemine opened 1873 in the French Provence and that the
bauxite orefor the first time was scientifically described 1821 have to
berevised.
About this necessary revision here the essential proofs areproduced.

Summary: The open pit "Vrtlinska"is according to its dimensions and
production capacity the biggest one in this regions. Exploitation reserves
within this open pit amount about 11 000 000 t glass sand of a very good
quality, and the production capacity is 200 000 t yearly according to real
needs during design and opening the pit. This article disccuses geological
and geomechanical characteristics of the deposit, as well as the
exploitation process, which is considerably matching natural
characteristics of the deposit. A more detailed description is given of the
planned exploitation phase I above groundwater level which is carried out
according to discontinuos system. For the exploitation of the depth part
under groundwater level in the phase II, the necessity of further
examination of hydrogeological characteristics of the deposit is presented,
in order to acquire necessary information on groundwater regime and
drainage conditions. Such knowledge will influence the choice of most
appropriate solutions in the exploitation of the depth part of deposit.
Keywords: Glass sand, open pit planning, working and final slopes, waste dump, Vrtlinska.

Summary: The paper deals with the selection of materials for the
sealing layer in the final cover of sanitary landfills. The sealing layer
is the most critical component of the final cover. Its role is to minimize
percolation of water through the final cover. Materials used for the
construction of the sealing layer are either of mineral origin (compacted
clay) or geosynthetic (geomembrane). They are most often used in
combination creating composite liners. Recently alternative materials are
also used like paper mill sludge or discarded swelling clay.
Keywords: Sanitary landfill, Municipal solid waste, Final cover, Sealing layer, Compacted clay, Geomembrane, Geosyntetic clay liner, Paper mill sludge, Discarded swelling soil.

Summary: Decline in output of coal in Croatia started in the
begining ofsixties, as a result of reduction in coal consumption.
Theconsequence was closure of all lignite and brown coal mines by1976 and
serious reduction in production of hard coal. Themaximum coal production
late fifties was more than 2,5 milliontons/y what covers, more or less, one
third of energy needs ofCroatia, fell in 1992 to 120.000 t/y of hard coal
what coversonly 1,72% of energy needs. Estimated reserves of coal
areremarcable, paricularly of lignite and than comes brown and hardcoal.
The coal will remain vital to industrial development in theworld, with
present production of 4473 million t/y and withincrese by more then 1%
annualy by the year 2010. In Croatia,investment in new coal mines is not
satisfactory due tounfavourable montan-geological condition of deposite.

Summary: The church of St. John the Baptist in Kloštar Ivanić is
anexample of late gothic architecture. It is the largest buildingof that
kind in continental Croatia. After a number ofdevastations and restorations
only plain outer walls exist today.Two counterforts are missing as well.
The paper describes a possible method of renewal of the shrine
bystrengthening the existing structural elements. This method
ofreconstruction is deemed superior in comparison to thealternative
approach which proposes demolition and rebuilding ofsome walls of the
shrine.

Summary: Within the framework of municipal solid waste management it
is necessary to construct sanitarylandfills. This task has by no means
interdisciplinary feature but with pronounced geotechnical role. The main
problems to be solved are, among the other problems, settlements and
stability of waste material in the landfill. In relation to these problems
the paper deals with the mechanical behaviour of municipal solid waste.
Classical soil mechanics approach is addopted but the differences between
the soil behaviour and waste behaviuor are emphasized. Using some published
data from the literature several experimental procedure for the
determination of shear strength parameters are presented. It is concluded
that there is every reason to introduce the term "waste mechanics".

Summary: Sanitary landfill is considered as an earth structure. The
paper discusses the issue of impermeability of the clay barriers within the
criterion for the achievement of maximum density of cohesive soil. This
criterion which is usually applied in geotechnical assignments needs to be
modofied due to the requirement on the valeu of maximum allowedhydraulic
conductivity of a lay barrier. In relation to this requirement the paper
stresses the importance of an effective method for hydraulic conductivity
measurement in the laboratory as well as in the field. The issue of the
chemical interaction between leachate and clay is underlined in connection
to the possible deterioration of clay properties.

Summary: Waste disposal does not belong entirely to any of the
traditional engineering disciplines. The reason is that, until recently,
waste disposal was not considered to be a major problem in the society and
cosequently it did not attract adequate attention.
Today when the quantity of waste has enormously increased and when the
society has become aware of the adverse impactof different waste materials,
new methods of waste disposal are being sought. These methods should
protect the environment for a long period of time. The problems which are
encountered in these activities are of interdisciplinary character and new
methods for their solution should be sought in several traditional
engineering fields.
The approach to the solution of waste disposal problems will remain the
same until new engineers are educated according to the needs of waste
management. The technology developed in geotechnical engineering has an
important role in the solution of environmental problems and it should be
considered in their solution. The paper offers a review of such problems
and the appropriate methods of solution from the field of geotechnical
engineering. Apart from the description of the existing methods which could
be applied directly, the paper points to the problems for which no readily
available solution exist. Therefore additional research is needed and new
methods should be developed for their solution.

Summary: The paper presents results of a stress-strain analysis in
the foundation soil beneath wharf No. 5 in Ploča harbour due to fill load
on the adjacent depot. Initial stresse on the foundation soil were
determined under drained conditions, while stresses due to fill load on the
depot were calculated assuming undrained conditions. Soil - wharf structure
interaction was taken into account. Soft foundation clays were modeled by
an elastoplastic constitutive equation. It was shown that the presented
analysis gives realistic displacements and stresses in the foundation soil
and the wharf structure.

Summary: Regional characteristics of Dubrovnik and Montenegro zones
of the Adriatic coast are the existence of block paleoslides and the
occurence of strong earthquakes. Rock blocks on the flysch slope are found
at present. Various buildings are constructed on some blocks. The aim of
the paper is to analyse recent state of block stability and the possibility
of reactivation of landslide due to earthquake. The clear differentiation
of the engineering geology elements of the slopes, which represent the area
of high contrast of physiacl and mechanical characteristics, follows the
hydrogeological division on permeable and impermeable rocks. The possible
sliding surfaces were once the mechanical active planes and at the same
time are border-lines between two geotechnical media - the rock block and
the quasiplastic base. The flysch complex is adopted as the seismic
footwall. The paper includes stability analysis under seismic conditions
with the parameters of the montenegro earthquake in 1979.

Summary: Discontinuities are one of the most important factors
contributing to the instability of rock slopes. In the case when the rock
mass contains more than one discontinuity set, having unfavorable position
in regard to stability, it is difficult to assess the riskiest potential
sliding plane or system of sliding planes which determine the type of
failure. The problem is getting more complicated when geological,
geomechanical and geometrical conditions on the slope vary on relatively
small distances which is quite often in the case on the open pit mines and
road or rail cuttings. In the paper the procedure of determining the most
unstable zones and potential sliding planes is given, by which a type of
possible failure or sliding can also be estimated. An analysis of failure
criteripn for each element and each discontinuity is done on the basis of
intensity and principal stress direction data, gathered by means of finite
difference program FLAC. With the application of the procedure on all
profiles of pit slopes or cuttings it is possible to get a complete
information on rock slopes stability.
