Abstract: Aiming at the problems of difficult operation in confined space and poor cooperative working ability of multiple machines in thin coal seam fully mechanized mining face,intelligent system is built. A shearer positioning method based on multi-signal fusion of infrared, radio frequency and shaft encoder is proposed., the working face straightening technology based on inertial navigation and supplemented by video signal is established. Intelligent support systems such as emulsion pump station intelligent system, spray intelligent system, three machines and belt machine fault diagnosis system are built. An integrated control platform is set up in the crossheading centralized control center, based on advanced and reliable electro-hydraulic control system access to each subsystem through multiple data interfaces, use industrial bus network as the channel, realize underground centralized control and ground remote control. The industrial operation shows that the system can realize the automatic production of the whole process of coal mining in the working face, the production team of the coal mining team at the working face has been reduced by 5 people, the number of personnel has been reduced by 30%, the average daily advance is 6 knives, and the production efficiency has been increased by 102%.
