Abstract

In many Underground workings, either for mineral production or for creating lines of communicauon, mobile machines have to operate under conditions that are very difficult for personnel and equipment. Problems such as excessive dust, rock falls, high temperature and humidity, or the presence of an explosive atmosphere are not uncommon. Today, it is possible to monitor such machinery from a surface Station, in real time, using a highiy reliable digital transmission System (developed by INERIS), at distances of up to 10 km from the working. Similarly, difficulties arising from in-situ maintenance have led to the development of an on-line malfunction diagnosis System that can detect such malfunction and halt Operation by a conditionnal programmed stop. The Software has been developed using Expert System techniques with GENESIA l (EdF-STERIA) and the hardware is compatible with IBM PC-AT. On-line communication is under JBUS protocol. Full analysis (data acquisition - processing - Output) takes 20 seconds. The system can be intemipted at any moment to obtain correct Status of Operation.
