ROCK MECANICAL ASSPECTS SIMULATIONS IN THE FUTURE OPEN PIT DEVELOPMENT

The proposed mining in a Porphyry copper deposit appears primarily restricted by the geometry/geomechanics of the deposit and secondly by mining methods and technology. The geometry/geomechanics of one deposit can be divided into three sections including western block and middle and eastern block. The greatest width has so far been discovered in the an middle block; all available information indicates that this will not change when the pit/mine is deepened. Assuming more or less continuous conditions within the three blocks towards the northern (rock will be added in the model) and southern rock) neighboring rock the greatest depth of the pit (> 511 m depth) will be reached in the middle block.
