Abstract

This bachelor work focuses on the non-detonating expansive rock breaking system (Green Break Technology - GBT) and its comparison in practical areas with conventional blasting. The first part describes the properties of the product. Then they discussed the possibility of using the GBT for breaking rocks, for example breaking oversized pieces or tunneling. The next part is evaluated using seismic measurements at GBT disintegration of rocks in the workplace Experimental Geotechnics on the table Josef. Following are designed conventional drill and blast and calculated Seismic load caused by drill and blast. Both methods are then compared. It is also evaluated and presented its own seismic measurement and throwing in experimental rock breaking via GBT made in Jílové near Prague on the mine "Pepř" and in a quarry in Kozárovice.
