DEFINING THE BASIC CONDITIONS FOR THE APPLICATION LONGWALL PRINCIPE HORIZONTAL MERGER
Getting coal using mechanized longwall on the principle of horizontal concentration in a single procedure, it can be successfully applied in mining coal seams very small thickness. For high calorific coal thickness of coal seam that can be successfully excavate this method is approximately 1.0m other coals to 5.0 m.Result of extensive laboratory re...

THE VULNERABILITY DETERMINATION OF GROUNDWATER BODIES IN SOUTHEASTERN BOSNIA ACCORDING TO DRASTIC, GLA AND EPIK METHODS
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, ...
