Fault Analysis and Diagnosis Technology and Development Trend of Coal Mine Machinery and Equipment

Fault diagnosis of coal mine machinery can effectively avoid accidents, reduce maintenance time, and reduce maintenance costs, which is of great significance for the development of high yield and high efficiency in coal mines. In this paper, three kinds of eight kinds of fault diagnosis methods are described in detail, and the shortcomings of fault diagnosis methods are analyzed. In view of the existing problems, a prediction model combining multi-theory techniques in the future is proposed to overcome the shortcomings of a single theory. Promote the development of fault diagnosis theory; New on-line monitoring and analysis techniques are constantly introduced. In the aspect of hardware, the software is strengthened, and the monitored data is realized by the algorithm of signal processing. Fault diagnosis is a dynamic and complex problem, especially under the complicated underground geological conditions, the nonlinear problem will be a key problem to be overcome in the future.
