Avaliação técnica de métodos de decapeamento de jazida de gipsita

Abstract

Gypsum gas ore stripping methods at the Polo Gesseiro do Araripe involve mechanical dismantling, loading and transport of sterile. A good choice of the applicable stripping method, if it is a relevant factor in mine planning, without technical, economic and environmental sense, therefore, in order to achieve more technical and operational efficiency, design a hydraulic excavator, a conveyor. of conveyor belts and trucks within the mine by adopting the Terrace Mining method. From a washer sequencing and considering the conditions of use of the Polo Gesseiro, it was thus possible to make a technical and operational comparison between two ore stripping methods, the first method being the hydraulic excavator performed or disassembled or disassembled. the truck, the transport of the sterile, the second, a hydraulic excavator with the same function, but the transport of the barren is done by a belt conveyor. This analysis assists in the decision making process. Among the evaluated parameters and compared to the analyzed trucks, the energy efficiency of the belt conveyors, correlated with the low operating cost, lower labor quantity, higher safety and consequently higher productivity, makes it a totally viable alternative. technical and operational, but further analysis is required according to each project.
