Research on intelligent evaluation system of open-pit mine

In view of the lack of unified standards for the intelligent evaluation system of open-pit mines in our country, the lack of construction basis, evaluation criteria and other key issues in the construction process, research on the intelligent evaluation system of open-pit mines is carried out. An intelligent evaluation system for open-pit mines is proposed, covering: 8 first-level evaluation indicators, 29 second-level evaluation indicators and 1 system fusion factor. By adjusting the basic evaluation and system integration factors of the open-pit mine, three stages in the intelligentization process of the open-pit mine are given, namely, the intelligent mine preparation stage, the catch-up stage and the leading stage. According to the evaluation system and grading standards, an intelligent analysis and judgment of a large open-pit coal mine across the country was carried out. Through field research, it is finally concluded that the intelligentization of a large open-pit mine in Inner Mongolia is developing rapidly, but it is still in the preparation stage for intelligent construction, but it is developing towards the catch-up stage. At present, the intelligent shortcomings of the open-pit mine are concentrated in the blasting system, mining and transportation system, environmental monitoring and emergency management. In the future, the open-pit mine should continue to make efforts in the above four aspects in the intelligent construction.
