Comparative Cavability Studies At Three Mines.

This paper explains the rationale of the Bureau of Mines ongoing investigation that has the objective to develop procedures for precalculating the minimum span required for sustained caving and the size distribution of the caved ore fragments, based on rock mass strength tests and measurements of joint spacing and attitude. With the help of such quantitative design procedures the undercut-cave method can be extended to a much wider range of mineral deposit characterisics.
