【摘要】 薄煤层采煤机是薄煤层综采工作面的主要设备，采煤机的工作过程由滚筒调高和牵引速度控制两部分组成，行走时旋转滚筒割出一定形状和位置的顶底面形成了截割轨迹。由于截割轨迹决定了采煤质量与资源回收率，因此，薄煤层采煤机切割轨迹控制受到广为重视。本文详细研究了薄煤层开采工作面的煤层动态精细建模技术、广义记忆切割控制策略、工作面远程可视化监控技术等，基于三维动态精细建模识别煤层与顶底板的煤岩界面，辅助工作面高清视频系统实时控制采煤机摇臂高度，实现采煤机等装备的远程控制。研究针对薄煤层采煤机广义记忆切割，建立了基于煤层三维模型的采煤机煤岩界面识别系统，提出采煤机在煤层三维模型中实时状态描述方法及煤层模型实时修正技术，实现了薄煤层综采自动化工作面设备远程(顺槽或地面)控制，为建立薄煤层无人智能化工作面奠定基础。更多还原

【Abstract】 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.更多还原
