Considering the previous technology of memory cutting cannot adapt to the complicated geological condition in China, the technology of shearer self-adaptive memory cutting based on fuzzy control theory, the shearer positioning system and fuzzy control system of self-adaptive cutting are designed. These systems 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 when it works. The authors make the experiment of path tracing in laboratory and the experiment of self-adaptive adjust in Xi'an Coal Mining Machinery Co., Ltd. All the experimental results show that this technology not only can realize the shearer memory cutting but also can discriminate the abnormal state of shearer cutting rocks, then adjust the drawing speed and drum height self-adaptively. This technology can satisfy the control requirements under the complicated geological condition.
