Background
A tailings storage facility (TSF) primarily serves to store waste residues after ore separation. It is an indispensable link in mining production, preventing environmental pollution and safety hazards caused by the random diffusion of tailings. Naturally, the stability of a TSF directly affects the surrounding environment, the safety of residents' lives and property, and the normal operation of mining enterprises.
The TSF on-line monitoring system is a set of modern technological solutions that conduct real-time and continuous monitoring of various key parameters of the TSF. Its purpose is to promptly grasp the operational status of the TSF, detect potential safety hazards in advance, and take corresponding preventive and remedial measures to ensure TSF safety.
Key Monitoring Items in Tailings Monitoring
Water Level Monitoring: A top priority, as abnormal water level changes may trigger dangerous situations such as flood overtopping in the storage area.
Rainfall Monitoring: Critical because rainfall increases water volume in the area and may cause risks such as dam erosion.
Dam Phreatic Line Monitoring: Reflects the seepage condition inside the dam, providing important references for judging dam stability.
Dam Displacement Monitoring: Includes surface displacement, internal displacement, horizontal displacement, and settlement monitoring, enabling assessment of dam structure stability by understanding deformation in different positions and directions.
Dry Beach Monitoring: Covers parameters like beach crest elevation, dry beach length, and slope, which are related to the TSF's flood regulation capacity and tailings deposition status.
Seepage Monitoring: Focuses on detecting tailings seepage to prevent contamination of surrounding soil and water bodies.
Video Monitoring: Provides intuitive observation of the TSF site, offering visual auxiliary references for other monitoring data.
FengTu FT-WK1 Tailings Monitoring System
As a professional environmental monitoring equipment manufacturer, FengTu has launched the Tailings Monitoring system (model: FT-WK1) to facilitate customers' TSF safety monitoring.
System Configuration
Water Level Monitoring: FengTu employs a high-frequency radar level gauge, featuring high measurement accuracy and fast response to real-timely capture continuous water level changes, providing timely and accurate data for water level regulation and safety early warning.
Dam Displacement Monitoring: GNSS Receivers acquire high-precision 3D position information of the dam surface, enabling precise judgment of displacement direction and magnitude through real-time data comparison.
Deep Horizontal Displacement Monitoring: Fixed inclinometers installed in boreholes within the dam measure displacement at multiple points along the depth, intuitively reflecting deformation at different depths to analyze internal stability.
Pore Water Pressure Monitoring: Pore water pressure gauges track internal pore water pressure, whose changes affect effective stress and dam stability, providing key data for stability assessment.
Video Monitoring: HD network bullet cameras capture real-time, all-round high-definition images of the TSF site (dam surface, water status, surrounding environment), allowing managers to remotely visualize operational conditions and detect anomalies promptly.
Rainfall Monitoring: Rainfall measuring equipment provides accurate rainfall data for flood early warning and water level prediction.
Monitoring Standards
The FT-WK1 system complies with:
Technical Regulations for Tailings Storage Facility Safety (AQ2030-2010)
Engineering Technical Specifications for On-line Safety Monitoring System of Tailings Storage Facilities (GB51108-2015)
These standards detail technical requirements, monitoring contents, methods, and system operation/maintenance to ensure scientific, standardized, and effective monitoring.
System Advantages
The FT-WK1 system enables comprehensive, real-time, and precise monitoring of multiple key TSF parameters, detecting potential hazards promptly to provide scientific data and decision-making support for safety management. Its high automation and intelligence reduce manual inspection workload and risks, while remote monitoring and data transmission allow managers to access TSF status anytime, anywhere.
With rich R&D and manufacturing experience in environmental monitoring equipment, FengTu—equipped with a professional technical team and comprehensive service system—delivers high-quality products and after-sales support, establishing itself as a reliable choice in TSF safety monitoring. We look forward to cooperating with you.
