Abstract:Purpose: In response to the problems of low mechanization, low production efficiency, large number of workers, difficult production management, and high safety risks in the ordinary upward horizontal layered tailings cemented filling mining method used in a domestic fluorite mine, combined with the mining technology conditions of the ore body, the mining method is optimized. Method: Through the study of the structural parameters of the mining site, mining preparation and cutting engineering, and the mining process, an automated and intelligent upward horizontal layered tailings cemented filling mining method was ultimately determined. Intelligent mining equipment was used to replace manual mining operations, achieving few or even no personnel. Result: Production practice shows that this method is safe and reliable, and 5G remote control operation is achieved in the drilling, pilling, shoveling, and filling processes. Automatic positioning and autonomous rock drilling operations are achieved under appropriate control height conditions, and the number of workers can be reduced by more than 50%, achieving good economic and social benefits. Conclusion: With the gradual entry of mineral resources into deep mining in China, mining will face harsh and high-risk working environments such as high ground pressure and high rock bursts. The intelligent upward horizontal layered filling method proposed in this article has good reference significance and wide promotion and application value for deep and difficult to mine ore body mining.
