Underground mining by horizontal top slicing under concrete in the uranium mine of Oklo Fond in Gabon
Description
This article presents the mining method adopted in the uranium mine of Oklo Fond which belongs to Comut in Gabon, i.e. a method by horizontal top slicing under concreted backfilling. It discusses in particular: - the mechanical characteristics of the different types of concreted backfilling corresponding to their composition and their admixture of cement; - methods of placing this backfilling and their progressive improvement; - the bearing of this method on the problems of selectivity
