On June 17, 2024, the National Mine Safety Supervision Bureau issued a notice on the issuance of the 2024 Catalogue of Advanced and Applicable Technologies and Equipment for Mine Safety Promotion and the Catalogue of Outdated Processes and Equipment Elimination (Kuang An [2024] No. 68), promoting 44 technologies and equipment in coal mines and non coal mines. In order to promote the effective connection between advanced and applicable technology equipment and mining needs, and to promote the transformation and application of mining safety technology achievements, we have organized technical equipment holding units to produce relevant videos for learning and reference.
Name: Tailings Reservoir Flood Control Calculation and Water Condition Warning Platform
1、 Technical points
1) A fully automatic, high-precision, and adaptive dynamic flood control algorithm based on a time-varying nonlinear convergence model;
2) Driven by meteorological forecasts and rainfall, integrating real-time monitoring data for real-time diagnosis of water situation risks, advance warning and proactive warning at any time within the next 10 days;
3) Water situation prediction and forecasting cloud service platform.
2、 Common problems solved
Traditional flood control calculation techniques are usually based on specific working conditions and boundary conditions, using a fixed rainfall duration and assuming empirical rainfall patterns. However, they have drawbacks such as low efficiency, poor accuracy, detachment from production reality, and inability to predict and warn of water levels after short-term heavy rainfall or long-term continuous rainfall in advance. The platform is driven by meteorological forecast rainfall and integrated with real-time monitoring data to form a fully automatic, high-precision, and adaptive dynamic flood control calculation method for any duration and actual rainfall type. It realizes real-time diagnosis of water level risks and proactive early warning at any time within the next 10 days, which can comprehensively improve the prevention and control ability of tailings dam overflow and dam failure risks.
3、 Scope of application
Tailings pond.
4、 Application Cases
No. 4 Tailings Pond of Dexing Copper Mine of Jiangxi Copper, 43 Tailings Ponds of 37 subordinate enterprises of China Gold, and Jiamagou Tailings Pond of Xizang Julong Copper.
