Application and Research of High Precision Laser Positioning Technology for Fully Mechanized Underground Mining Equipment
In order to improve the safety technology level of intelligent mining in coal mines,solve the problem of low-cost and precise positioning and control of comprehensive mining equipment under complex underground conditions,the application and research of high-precision laser positioning technology for underground comprehensive mining equipment are carried out.Based on the analysis of the operation process of underground comprehensive mining equipment,this paper studies the establishment of the absolute coordinate system of the underground comprehensive mining working face and the measurement benchmark transmission and reconstruction method of the working face tracking and positioning system.Based on this,a laser tracking real-time positioning system architecture is constructed.This scheme has been applied in the underground operation of a coal mining machine in a certain coal mine.The results show that this scheme can achieve high-precision positioning function of underground comprehensive mining equipment,and the error of the displacement curve under continuous operation conditions is controlled within 20 mm,which can meet the operational requirements of underground comprehensive mining equipment.
