    2017-12-20 · Until the 1950s of the last century the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes a fine granulometry is produced and thus iron agglomeration

    In order to properly design a shaft it is necessary to acquire full information about the rock mass in the exploration area. It is especially crucial in the case of the deposit of an unusual vertical intrusion shape occurring at a great depth. Such a situation implies that the shaft lining design must take into consideration not only the geomechanical properties of the rock mass but also the
