Abstract: According to the backward status of the intelligent and remote automatic contral level of domestic shearer, the paper presented measurement system of body posture parameters of shearer and its measuring method.The actual condition of shearer, the position and orientation parameters of shearer was comprehensively defined, the measuring system of principles and structure detail were introduced and the field test and data acquisition record of the system was provided.The results s howed that the system could achieve comprehensive, effective, and accurate access of position and orientation parameters of shearer, and transmitted to the ground by underground data transmission system for display, it could provid reference to the achievement of digital mine and no-body coal mining face.
