Abstract: In order to promote the intelligent development of mines,improve production efficiency and management capabilities of mines,research on intelligent fully mechanized mining faces is conducted with Cheji Coal Mine as the research object,and significant results are achieved.The research combines with the actual situation of the working face,a design analysis is conducted on the type selection and matching of the main equipment for the intelligent working face.The equipment scheme of MG500/1130-MD3 type coal mining machine+ZY6800-16/35D type hydraulic bracket+SGZ800/2 × 700 type scraper conveyor is proposed.The key technologies for the construction of intelligent working face,such as 3D transparent geological modeling,equipment edge perception,GIS intelligent management and control platform and others,are analyzed to effectively solve the problems of unclear geological conditions and difficult human-machine cooperation in mines.The daily working efficiency of raw coal is improved by 365%,significantly improving the production efficiency of the working face.This item of research and application improvs the production efficiency and intelligent level of the mine itself,providing reference and guidance for other mines to carry out intelligent work.
