Popis: The underground mining is an activity that occurs in the depths of the rocky massif, which makes it possible to enter scenarios that may or may not be safe; This will depend on the quality of the rock and the engineering team. Until now, there is no support method that has been defined only considering the safety factor. For this reason, this research has been developed to use a type of support in gold mantles, in such a way that the spacings can be determined considering the maximum deformation lengths and therefore a safety factor. To determine the spacing between support elements, progressive results are taken as they contribute to the final stage of prediction of support spacing. Through the tests using the Rocscience RS2, spacings with probabilities of 90% compliance and with safety factors of 1.7 were determined; which allows to give more security and confidence in the work of auriferous mantle.
