Solution Architecture

Big Data Platform

Based on the GIS geographic information system platform, the tailing pond automated safety monitoring and early warning system (big data platform) adopts the centralized and distributed application mode of data and application system, comprehensively integrates three-dimensional multi-source heterogeneous data such as inclined photography, laser point cloud, standard model, etc., and realizes the integration of air and sky, the integration of information integration, analysis and display, which can realize the functions of risk in comprehensive monitoring, risk intelligent assessment, risk accurate warning, risk trend prediction and judgment, basic data of tailing pond, emergency work management and system management. trend prediction and judgment, basic data of tailing ponds, emergency work management and system management.

Monitoring platform

The tailing pond safety monitoring and early warning system based on BeiDou high-precision positioning integrates advanced technologies such as BeiDou, sensors, big data and cloud computing to realize all-weather monitoring of data such as surface displacement of the dam body, internal displacement of the dam body, soak line, elevation of the top of the stall, length of the dry beach, water level in the reservoir area, rainfall, safety over-height, video surveillance and surface displacement of geological landslides in the reservoir area. In addition, the system carries out water vapor inversion for tailing ponds in order to realize regional gridded weather warning, so as to meet the real-time collection, intelligent analysis, risk identification and rapid warning of tailing pond status parameters and other related information.

Water vapor inversion function module

Ground-based Compass-BeiDou researches three-dimensional water vapor inversion technology to realize high-precision real-time monitoring of atmospheric water vapor content and prediction of future precipitation. Compared with the traditional means of meteorological detection, the water vapor information obtained by Ground-Based Compass has the advantages of high accuracy, high temporal and spatial resolution, cost saving and being independent of time.

Project Cases

Chenkeng Tailings Storage Safety Monitoring and Early Warning Project

Chenkeng tailings pond is designed to have a final stacking elevation of 625m, a total dam height of 205m, a total design capacity of 47,811,000m³, a catchment area of 3.992km³, and a design grade of second-class tailings pond. The existing monitoring system in the reservoir area has been unable to comprehensively assess the safety risk level of the tailing pond, and it is necessary to establish a more complete and comprehensive monitoring system. Through the construction of the third phase online monitoring system, there are 33 surface displacement monitoring stations, 6 deep displacement monitoring stations, 19 groundwater level monitoring stations, 1 beach top elevation and dry beach length monitoring station, 1 reservoir water level monitoring station and 1 rainfall monitoring station.

Qiu Cheng Tailings Storage Safety Monitoring and Early Warning Project

The total height of Qucheng tailings dam is 86m, forming a total storage capacity of 5.8 million m³, and the design grade is second-class tailings storage. The existing monitoring system in the reservoir area showed some sensors aging and damage, which could not meet the demand for intelligent safety monitoring of tailing ponds. After the design and renovation, a total of surface displacement, deep displacement, dip line, dry beach length, reservoir water level and meteorology and other monitoring stations have been constructed, and an intelligent safety monitoring and warning platform for tailing ponds has been built, which realizes comprehensive early warning of monitoring data of Qiu Cheng tailing ponds through the fusion of heterogeneous information from multiple sources.

Bucket Fishing Ling Tailings Storage Safety Monitoring and Early Warning Project

Bucket Fishing Ridge Tailings Reservoir is designed to have a final stacking elevation of 779m, with a total capacity of about 8,745,700m³, an effective capacity of 6,122,000m³, a total dam height of 88m, and a design level of third-class tailings storage. The existing monitoring system in the reservoir area can no longer satisfy the safety risk identification and rapid warning of the mining area, and needs to be equipped with a more complete and comprehensive monitoring system. As of April 26, 2021, the Beidou/GNSS surface displacement monitoring station, dry beach monitoring station, dip line monitoring station, reservoir water level monitoring station and rainfall monitoring station are all online. It realizes the integration, analysis and display of information from heaven, earth and space, and achieves the functions of comprehensive risk monitoring, intelligent risk assessment, precise risk warning, risk trend prediction and research, and emergency work management, etc. It meets the real-time collection, intelligent analysis, risk identification and rapid warning of the state parameters of the Bucket Fishing Ridge Tailings Storage Pool and other related information.
