Abstract: The article takes advantage of the independent researched and developed intrinsically safe vibration data recorder as vibration measuring device, Based on the actual vibration under different cutting conditions of shearer information collection and analysis formed an information database that contained vibration signals under a variety of cutting states. Meanwhile, the article has summarized coal shearer’s vibration characteristics respectively in coal cutting and rock cutting conditions through analyzing the vibration data in time domain. On the basis of the analysis consequence, an effective coal-rock interface recognition method has been put forward.
