Determinação de blocos de partição em maciços rochosos através de planos de descontinuidades com uso de VANTs.

Rocky massifs are defined as a set of juxtaposed and articulated blocks of rock, limited for the discontinuity plans (fractures, joints, failures and foliations), whose families directly affect the appearance of the massifs in terms of alternative open pit mine planning. Aerophotogrammetry employed at work for the using UAV (unmanned aerial vehicle) was adequate to assist in the information acquired with the capture of aerial images and lifting the scan face, on the north and east benches of a quarry for the production of aggregates for civil construction located in the forest area of the state of Pernambuco. After creating the model, with the aid of a CAD tool and the diagnosis of the most highlighted fractures, with descriptive statistical analysis, stereographic projections through the wulff net and and the Rosette Diagram of the discontinuity plans, the partition blocks of the north and east benches of the studied massif were interpreted. The use of vant at the paper, increased the level the work the treatment of data collected from scan face and provided the identification of the partition blocks, as well as other areas of weakness in the massif, that enable possible changes in the interpretation of engineering projects.
