Abstract: In order to accelerate the pace of intelligent mining construction, the research on unmanned mining technology of fully-mechanized mining face of thin and medium thick coal seams is carried out against the background of the construction of 43-02 working face in Dongtan Coal Mine. The new measures of unmanned intelligent mining construction, such as the innovative video monitoring system of the 43-02 working face, the innovative bracket following machine, the simulated manual pushing process, the joint control of the bracket controller, the remote operation of the centralized control center and the optimization of memory cutting, are put forward. The construction results show that through the "five in one" measures, the labor efficiency has increased by more than 70%, and the new model of unmanned intelligent production has been gradually built, and the new problems faced in the process of intelligent construction of the working face have been pointed out.
