    • Abstract
  • This paper introduces the research status of intelligent technology of shearer at home and abroad. Since the 1990s, the intelligent technology of shearers has entered a mature stage of development abroad, and leading innovations have been made in shearer memory cutting, coal and rock identification, airborne main control software and remote monitoring. The intelligent development of domestic shearers has shifted from introduction and absorption to independent innovation, basically realizing primary intelligent fully mechanized mining. According to the different functions of shearers, intelligent horizontal classification is divided into four categories, intelligent perception, intelligent control, intelligent diagnosis and intelligent communication. The key technologies of intelligent perception include posture perception, operating environment state perception, airborne video perception, personnel proximity identification, intelligent anti-collision detection, straightness perception and coal rock identification perception. The key technologies of intelligent control include drum automatic height adjustment control, adaptive speed adjustment control, environmental gas linkage control, coal flow load balance control, and pitch guidance control. The key technologies of intelligent diagnosis include real-time online diagnosis technology and the whole life cycle management of shearer. The key technologies of intelligent communication include wired communication technology and wireless communication technology. According to the human intervention in the coal cutting process of shearer, intelligent longitudinal gradation is divided into four grades, auxiliary automation, primary automation, advanced automation and intelligence. Through the intelligent classification and gradation of the shearer, the intelligent function of shearer can be visually consulted, and the intelligent grade of shearer can be determined by judging conditions, which provides quantitative reference for intelligent mine construction rating, and also shows the context of intelligent development of shearer more clearly.
