Determination of Stresses and Deformation During Measurements with Loading Method on Central Ore Pillars in TREPCA Mine

摘要

The most rational mean of using ore body in TREPCA mine is to put security pillars from the ore, these pillars have square cross section size at starter 10×10 m. This way of formation of pillars is done utilizing central ore troops which have great amount of the ore body. Whether the pillars formed analyzed in terms of sustainability, we can state that they are stabile and they possess a high safety factor. We have to state that for the first time determination of stresses in pillars of ore is done in workshop 130 directly with method of measurements.
