Ecology and Environmental Protection
During the European GoldenEye Project Type H2020 Number 869398, three drilling and blasting methods were analyzed in terms of the impact of the works on the environment, the choice of the most optimal scheme from the point of view of rock strength, the reduction of costs and the reduction of the impact of the environment. Here, the environmental footprint of the operation was significantly reduced. Analogous and graphic calculation methods were used using the programs Rhinoceros 3D combined with RhinoTerrain and O- Pitblast, but also topographical elevations with the drone necessary for the realization of the 3D geometrization of the open pit itself. The geomechanical parameters of the rock, geological and structural maps were used for the most accurate planning of the drilling and blasting site. A significant reduction in design times (77%) could be implemented in the design of the works. Optimizing rock mass removal was an important objective in the exploitation of mineral resources due to costs, risks regarding personnel protection. The method of extraction by using the drilling and blasting has been continuously improved by combining practical experience with the theory of explosions and the formation of explosive substances, statistical processing of the data obtained from the blasting, development of analytical, numerical, and graphic models. In the last period, the design activity of the grilling/blasting monograph has been perfected through numerical and graphic methods, facilitating the work of engineers in this field. This design is based on the data provided by the engineers detailing the geological structure of the rock mass to be extracted and the use of the mining product (crushing or grinding needs, use as rough stone, rock deposits, crushed stone, blasting rocks for slope stabilization). This paper analyzes the monograph for geomining and crushing/grinding conditions from Rosia Poieni.
