Abstract: This paper first analyzes the existing problems of open-pit coal mine from the perspective of industry background, policy guidance, management and control concept, expounds the necessity of establishing intelligent mine, studies the definition, overall framework and construction planning of intelligent construction of open-pit coal mine. According to the 1+ 4 mode, i.e. 1 comprehensive management and control platform, 4 levels(equipment sensing layer, integrated communication network transmission layer, internet platform layer and software application layer), we carry out the construction of intelligent mine, and plan the specific content of the construction by stages, analyze the key technologies in the process of intelligent construction, and discuss the important role and subsystem composition of the intelligent management and control platform of open-pit coal mine.
