Research On The Generalized Memory Cutting Technology Of Thin Seam Shearers Based On Dynamic Fine Modeling

Thin seam coal mining thin seam longwall face equipment, the shearer work process has twoparts, the drum lift and traction speed control. The shearer when walking, the rotation of the drumcan be cut out of a certain shape and position of the underside of the top, forming the cuttingtrajectory. Cutting the track to feel that the quality of the coal resource recovery, therefore, Shearertechnology research has been widely valued.This paper presents the coal and rock identification system based on detailed geologicalsurvey data, the seam data obtained by the Geological Survey, real-time adjustment of the heightof the shearer rocker. Compared with traditional coal and rock identification system, the paper ofcoal and rock identification system without Shearer take the initiative to make the identificationsignal and identify the boundaries of coal and rock, but thin seam shearers generalized memorycutting through the establishment of three-dimensional dynamic lean model. Basedthree-dimensional model based on coal seam shearer coal and rock interface recognition system,the establishment of the real-time status of the shearer in the coal seams in the three-dimensionalmodel description method to study the the seam model real-time correction. Based onthree-dimensional visualization of dynamic lean modeling, through the identification of coal-rockinterface, combined with face-definition video systems, automation mechanized mining faceequipment remote (the trough or ground) the feasibility of control, unmanned face.
