This report deals with studies in the Lorraine collieries involving the development of novel techniques allowing for the long range remote control of shearers and for their full automation based on supervision and control tools using real-time computers. The method of automatic horizon control developed was based on a learning strategy, with a first calibration pass used for control of drums in following passes. Further developments were carried out on a different machine (shearer DTF-HBL) used in regular semi-steep seams. The experimental system installed there was based on the new TELSAFE DV-CA which allowed mixed remote control modes. Studies have also been carried out on new sensing techniques for mining environment. The results presented show that the analysis of machine mechanical vibrations spectra is a promising technique. Infra-red vision is also of great interest for both coal interface detection and machine guidance problems in very dusty environmental conditions.
