Entre los procesos que se ocupan para la extracción subterránea destaca el hundimiento por bloques (block caving), en el cual la extracción se realiza gracias a la fuerza de gravedad. El Proceso consiste en dividir el cuerpo mineralizado en bloques rectangulares y quebrar cada uno de estos en forma separada siguiendo una secuencia, mediante ...

8.4.2a Block Caving. This method, which was developed in the U.S. after WW I, is well suited for mining in weak orebodies. Panels or blocks of ore are undercut. Once undercut, the weak orebody begins to cave under its own weight. The caved ore is drawn off through draw points.

Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight ...
