The coal petrography identification technology for the coal mining machine based on information fusion technolo- gy is studied. The multiple sensors instead of the traditional single sensor is used to establish the coal petrography identification system, and the fuzzy neural network algorithm is taken as the core algorithm to improve the stability, anti-interference ability and accuracy of the coal petrography identification for the coal mining machine. The vibration, resistance torque and motor cur- rent are monitored when the roller of the coal mining machine is cutting the coal wall, and the characteristic value is extracted by data collection. The characteristic value is conducted network training by fuzzy neural network algorithm, and the coal petrogra- phy identification model for coal mining machine based on neural network and information fusion is obtained. The performance of the coal petrography identification model is verified by experiments, and the results show this identification model can identify the coal petrography interface effectively, has higher identification precision, better reliability and stronger stability than that of the traditional single sensor and single identification technology.
