The Cerro Lindo Mine is the largest underground mine in Peru, currently mining more than 20,000 tonnes/ day. The sublevel stoping method was used with paste backfill, which had been experiencing overexcavation issues at the hangingwall and the front wall of the

The first comprehensive work on one of the most important underground mining methods worldwide, Geotechnical Design for Sublevel Open Stoping presents topics according to the conventional sublevel stoping process used by most mining houses, in which a sublevel stoping geometry is chosen for a particular mining method, equipment availability, and work force experience.

Summarizing state-of-the-art practices encountered during his 25+ years of experience at industry-leading underground mines, the author by Ernesto Villaescusa. Geotechnical Design for Sublevel Open Stoping. Something went wrong. View cart for details.

El mtodo sublevel stoping es un mtodo de explotacin con sostenimiento natural, en el cual se emplean pilares en el rumbo o buzamiento de la zona de inters. El rumbo es la lnea imaginaria que se traza al intersectar el plano geolgico del rea de explotacin y un plano perfectamente horizontal.

En cuanto al ancho del casern, conviene en general en la caso de vetas potentes o de mantos de fuerte pendiente, abarcar todo el espesor de la mineralizacin. Si se trata de cuerpos masivos se pueden crear varios caserones separados por zonas estriles o pilares mineralizados que podran ser recuperados con posterioridad utilizando el mismo mtodo.

Stoping is the process of extracting the desired ore or other mineral from an underground mine, leaving behind an open space known as a stope. Stoping is used when the country rock is sufficiently strong not to collapse into the stope, although in most cases artificial support is also provided.
