One of basic problems faced in practice of landfill waste treatment is a problem relating to landfill leachate. The intensity of their production, thus their quantity, depends on numerous factors: landfill age, waste types, microclimatic parameters and similar. This leachate must not be discharged directly into the environment without its previous ...

During construction, especially of tunnels, very often there is a need to change the tender technical documents, i.e. the documents upon which the construction permit is obtained and the tender is announced. The main reason for the change of documentation is, above all, unsuficient geotechnical investigations due to which technical solutions and ca...

Today's building of facilities does not follow the study of the characteristics of the terrain on which the facility is constructed. The period of rapid construction, which can be called the "modern construction" does not follow the quality of constructed facilities. Usually it is the uncontrolled building, where is only important to build a facili...

Qualitative characteristics of bauxite deposit „Oštrelj“ are defined through extensive laboratory testing of chemical and mineralogical-petrographic composition, and geomechanical characteristics. Chemical composition has shown that it is a relative poor bauxite with low Al/Si module (2,28). Low values of Al/Si module are result of lower Al2O3 conc...

The vulnerability results of groundwaterbodies of southeastern Bosnia are shown in this paper. On the examined area 27 groundwater bodies were extracted, where 12 groundwaterbodies are in rocks with intergranular porosity and 15 groundwaterbodies are in rocks with karst-fissure porosity. All of the groundwater bodies were analysed through DRASTIC, ...

This paper presents the results of the calculation of coal reserves obtained by classical method (calculation method of geological blocks), which were compared with the results obtained by the calculation using software. Since this area was explored for long period of time and elaborates were done in past, we came to an idea to compare results from...
