- Abstract
The State of Espirito Santo, being the largest exporter of ornamental rock in the country due to the large number of extraction front that is in the state, and to remain competitive in this market, the sector is always in search of new technologies that will increase its production and reduce their costs. With this evolution the ornamental rock sector of the holy spirit has developed a new technique of extraction that are the ultra-high benches, where to stop using the traditional benches up to 20m and started using benches that reach a height of 100m. This new technique allows for greater productions and a better recovery of the stone material, besides increasing the profitability per cycle of extraction. In order to use this method, we have to observe some factors such as rock type, solid state, higher initial investments, time for dismantling and specific equipment for the extraction work. This type of method is still not widespread, as it is currently only used by some national companies, but its efficiency is proven, compared to the use of conventional benches, this method can generate a profit higher than conventional methods.
