  Geotechnical Design of Large Openings for Mining Operations in Chile

  The paper summarizes the methodological approach considered for the geotechnical design of large underground openings, with particular reference to the authors´ experiences on a number of projects developed for mining operations in Chile. The stepwise design approach includes the geotechnical model, the assessments of the stress field, relevant boundary conditions, the analysis of the rock mass behavior and the ground-support interaction, additionally addressing the construction baseline scheme and some significant aspects associated to the construction stage. Two case histories of large underground facilities developed for the mining sector in Chile, where this methodology has been implicitly applied and proven adequate, are presented to illustrate typical challenges and conditions faced by the design and construction of these types of underground structures.
