Study on Fault Diagnosis of Coal Planer Based on Factor Space

Coal planer has special advantage in thin coal seam and the gas mining working face, but inevitably often break down because of poor working environment, so it is meaningful to research on its fault diagnosis. In this paper, fault diagnosis problem of coal planer is studied based on the theory of factors space. In the factor space, the fault diagnosis of coal planer is described through its symptom factors set together, through factor analysis, got the fault type. Finally, the simulation analysis of fault diagnosis for the coal planer is carried out, simulation results show that the fault diagnosis method based on the factor space theory can obtain the fault type of coal planer correctly.
