Rock mechanics and the economics of cut-and-fill mining

Abstract

The application of rock mechanics to mining has great economic potential. Factors such as loss of ore, rock-dilution, possibilities of machanization and rock support are all influenced by the degree of rock mechanics involvement. In particular loss of ore is limited by the correct dimensioning of pillars and remnants. Rock-dilution, depending upon caving, can in the same way be mastered by the right dimensions of stopes and pillars and of rock supporting. Possibilities of mechanization depend upon sizes of drifts and stopes, stope availabilities and access to the stopes, all depending upon a considered rock mechanic investigation. Also shut-downs in the stopes owing to caving can be affected in the same way. Consequences on the mining economy for cut-and-fil mining are illustrated concerning loss of ore, rock-dilution, mechanization levels and rock support. The biggest influence can be made on rock-dilution and mechanization. Under special circumstances loss of ore can be of the same magnitude, namely if the ore production per year is directly influenced by the loss of ore and can not be compensated by other mining activities. Rock support is of less economic importance compared with rock-dilution and mechanization, presupposed no less of ore-production.
