Abstract: With the continuous progress of digital intelligence transformation in mining industry, mining enterprises begin to accelerate the construction of new industrial information infrastructure. A mine visualization cloud platform based on geographical information, production data, and network data convergence supports comprehensive mine management and decision-making oriented to ore flow, which is an important prerequisite for building intelligent and green mines. Based on the background of promoting the intelligent application of 5G remote mining technology in open-pit mines of Pangang, this paper designs and implements a 5G fully connected mining digital twin visual management system based on information technologies such as 5G, Internet of Things, cloud computing and 3D GIS. Integrated and dynamic supervision of mining equipment, 5G network, production and operation of key production factors, open-pit mines to achieve essential safety, scientific and effective management and decision-making to provide technical support.
