Abstract

The aim of this research was to make optimal use of mining equipment for rock drilling by concentrating on the workings the best equipment, compatible with the sections that have been mined, and in particular for the drilling, the excavation and the set up of the supports.

Even if it has not been possible to gather in one site all the necessary equipment that this study mentions, this research has nevertheless helped to improve the rock drilling of Les Houillères in the Lorraine Basin by more than 22%. Indeed, the use of tracked armoured conveyers has been generalised throughout all the sites in Les Houillères in the Lorraine Basin, which has improved the average daily progress on this type of site by 3.6 metres in 1989, by 4.40 metres in 1992, when the actual sections dug were themselves increasing, within the same period of time, by 5% (from 24.2 to 25.4 square metres).

The research has reached its main objectives: maximising the drilling in this type of site, and making the task easier to the staff. Other improvements can of course be achieved, for instance by studying carefully the tasks accomplished individually by each worker, or by continuing to improve the existing machinery. ry.
