Modelling and Simulation on Shearer Self-adaptive Memory Cutting

Automation of shearer is the key point to realize the fully mechanized coal face. According to the complicated geological condition in our country, this paper built a shearer self-adaptive memory cutting model based on fuzzy control theory. This model contains shearer positioning system and fuzzy control system which can get the message of shearer's position and attitude at any point, trace the memorial cutting path automatically, judge whether the shearer cuts rocks based on fuzzy control theory and find the optimal scheme. The author simulated the working environment in laboratory and factory, did experiment to test whether the model can adapt complicated geological condition in the coal mine. The simulation results show that the model can realize the shearer memory cutting and discriminate the abnormal state, then adjust the drawing speed and drum height self-adaptively which can satisfy the control requirements under the complicated geological condition.
