Abstract: In view of existing status of different construction level and lack of unified industrial standard of smart mine, evaluation index system of smart mine was proposed based on definition of smart mine, and grading evaluation method of smart mine was developed to provide criteria and basis of smart mine construction. Meanwhile, architecture of smart mine was described from Internet of things perception layer, collaborative management and control layer, intelligent mine decision support layer and intelligent cloud decision support layer, and specification requirements of each layer content and relationship among the layers were put forward, so as to form unified measurement of smart mine.
