Abstract

The brasilian dimension stone industry has substantially increased lately, mainly by exportation of its refined or semi-refined products. The brasilian markets show a great variety and dynamism to attend the new aesthetic tendency of civil constructions. In spite of this, the archaic methods of block extractions are frequently shown yet. The present master thesis presents a methodology for computational modeling of dimensional stone quarry as a technical contribution to the sector of ornamental rocks, illustrated by a real exemple case of SOMIBRAS mine at Capão Bonito, SP. Although its general procedures are similars to the others mineral modeling works, this work have confirmed that in details the same procedures aren´t directly applied in this case, due to the peculiar characteristics of dimension stones. One of great problems faced by this study was the same difficulties found in major parts of brasilian dimension stone quarries: a generalized absence of geological and/or topographic data. The field searches emphasized the importance of these data, with special distinction for GPR system (Ground Penetration Radar) that provided mapping of deep fractures and its spatial interpretations. The benefits of computational technique are significants and could stimulate new research efforts to improve profits, feasibility and economical plans of dimensional stone quarries. (AU)
