Summary

With ever-rising labour costs, the mining engineer and the underground civil engineer look to mechanical excavation systems to increase productivity. The research described in this paper was part of a major and long term programme of experimental work carried out in the Mining Engineering Department of the University of Newcastle upon Tyne. One of the objectives of this research was to investigate the cuttability of evaporites. To this end each rock which has been tested for its cutting properties has also been subjected to a wide range of physical and mechanical tests. All the results are discussed in this paper.

Criteres d'abattage des evaporites

Résumé

Le prix actuel de la main-d'œuvre conduit les ingénieurs des mines et de génie civil travaillant en souterrain, à développer l'abattage mécanique. La présente communication est une partie d'un long travial effectué au sein de l'université de “Newcastle Upon Tyne”. L'un des buts de ce travail était l'étude de l'abattage des roches, dont des évaporites. Pour ce faire les essais d'abattage on été conduits en fonction des propriétés physiques et mécaniques des différents types de roche. La discussion des résultats a été faite le plus amplement possible dans ce papier.
