Abstract:

The tendency of equipments maintenance in coal mine is predictive maintenance. In this paper, remote health diagnosis system of important mechanical electronic equipments in coal mine (abbreviated as 4M System) was introduced, and related development on equipment normal maintenance, on-line monitoring, malfunction simulation and predictive maintenance model, as well as the shortage existed in field operation, were summarized to give better direction on coal mine equipment maintenance.

Key words: Equipment maintenance, Predictive maintenance, Remote health diagnosis
