Abstract

Abstract:

Dabaoshan polymetallic mine has a complex environment and high requirements for ore blending.Underground mining was used early.In the later stage，in order to improve mining efficiency and reduce safety hazards，open-pit mining was used.However，this led to the legacy of more untreated mined areas,and bring a big challenge to production work.Hongda Blasting Co.，Ltd. takes the Dabaoshan Project Department as its pilot unit and fully considers its role as a mine construction enterprise in the construction of digital mines.From the perspective of practicability and investment costs，digital mines suitable for mining construction enterprises was conducted.Based on the application of various advanced mining software，adhered to the actual needs of mine construction，the UAV aerial survey，DIMINE software and truck dispatching system were used as technical support，from the data acquisition，processing and application of open-pit mine,a digital mine construction framework that could be applied in various construction management stages was constructed.Firstly，the detailed terrain and 3D models of topography were obtained by the UAV aerial survey technology.The production status and the distribution of hazard sources were clearly understood，and the macroscopic survey of open-pit mine was realized.Then DIMINE software was used in the whole life cycle of open-pit mine for production planning，daily technical submission，engineering quantity settlement and blasting automation design，which realized the three-dimensional production planning and design of mines，ensuring the scientific exploitation of resources and reduced the depletion and loss of ore.At the same time，the truck dispatching system was used to carry out the mining and real-time dispatching management，which ensured the orderly mining construction and the effective execution of the mining instructions，so as to avoid the enforced idleness due to poor organization of work.The combination of UAV aerial survey，DIMINE software and truck dispatching system has realized the organic unification of mine status investigation，safety hazard identification，production planning and design，scientific mining，real-time supervision，etc.，ensuring safe production of the Dabaoshan open-pit mine.Practice showed that compared with traditional mine construction enterprises，Hongda’s digital mine pilot work has better realized mine integrated design and integration services in mining planning and design，construction and dispatching，and on-site supervision，which has significantly improved the refined construction the management level，it could provide a certain reference for the construction of digital mines in mining construction enterprises.

Key words: mining construction enterprise, digital mine, UAV aerial survey technology, DIMINE software, truck dispatching system, fine construction
