The paperпїЅs aim is improving the quality of higher education through the basic elements of e-learning and established models of e...

With organizing the excavation tehnology of loose raw materials through the boreholes, considering the complexity of technological operation, the most important thing is to calculate technical-technological parameters of exploitation and to make an optimal selection of pump aggregate, pipe line and pulp line, and also to project and construct the equipment for drilling and obtaining of concrete deposit conditions since there is no serial production. Hydromonitor presents its most important part that forms and dire...

Kolubara opencast mines are the biggest producer of coal in Yugoslavia. Current production is about 26 million ton per year from four mines. Probable reserves are about 2,6 billions, what is 19\% of total coal reserves in Yugoslavia Within coal open-pit mining activities in basin of Kolubara there are about 515 hectares (ha) of soil degraded by waste dumps that require recultivation. The paper gives a review of the areas at each coal mine to undergo recultivation in the forthcoming period. It also presents prepara...

Paper has show explorations of negative causes of underground coal gasification impacts to environment. Also is given view on importance of exploration on conquering technology of underground coal gasification in concrete deposit conditions.
