Abstract:With the development of industrial Internet, artificial intelligence technology and big data technology, the mining industry ushered in a new round of rapid development period in intelligence construction, and some non-coal mining enterprises have gradually begun to explore the construction of intelligent mines. As a new generation of decision support system, intelligent decision support system has become an important part of current intelligent mine construction, and has been applied in the business scenarios of non coal mining enterprises. Based on the application of traditional decision support systems, this paper summarizes the key technologies of intelligent decision making, and proposes a set of intelligent decision support system architecture for non-coal mines based on intelligent decision making technology, and verifies the viability of the architecture through practical case application in an underground iron mine, which may have a certain guiding implications for building intelligent decision support system in other non-coal mines in the future.
