Abstract:In order to continuously strengthen the safety monitoring management of tailings reservoirs in China and ensure the safe and stable operation of tailings reservoirs, an on-line monitoring system for open-pit flat tailings reservoirs was analyzed and studied. According to the actual operation characteristics of flat tailings reservoir and the parameters needed for monitoring, combined with a series of core algorithms, the flow seepage field of tailings slurry and the mutual stress field of tailings slurry were fused, and the practical theoretical model of tailings reservoir was established. The complete online safety monitoring system of tailings reservoir was designed from the two modules of system hardware configuration and software design. Field applications were implemented and the results showed that the monitoring screen could reflect the operation status of the tailings reservoir in real time; The monitoring data were stable and could form a curve trend, which was advantageous to the safety management prediction of tailings reservoir, and the overall operation stability of the system was maintained at more than 90%. which ensured the systematization, stabilization and practicality of the real-time online safety monitoring of the tailings reservoir, and the application effect was good. The application of this technology would be a scientific manifestation of the new platform of modern safety monitoring and decision-making, and it would provide some reference value for similar tailings reservoir data monitoring, which would be worth popularizing.
