Precision displacement detection system: precise crisis warning, building a strong flood prevention and safety defense line in mining areasModel recommendation:WX-WY1One stop service manufacturer chooses Wanxiang Environment
The precision displacement detection system of Shandong Wanxiang Environment Co., Ltd. is based on the core technology architecture of "full dimensional data acquisition+intelligent risk prediction", breaking through the industry pain points of "single monitoring parameters, lagging early warning, and high false alarm rate" of traditional mining area flood control equipment, and becoming the "flood control safety monitoring center" for key areas such as open-pit mines, underground tunnels, tailings ponds, and drainage ditches. The system innovatively constructs a "surface underground surrounding" three-dimensional monitoring network: surface deployed rainfall monitoring stations (range 0-500mm/24h, accuracy ± 2%), water level monitoring stations (range 0-20m, accuracy ± 1cm), soil moisture monitoring stations (0-100% vol, accuracy ± 1%), real-time monitoring of rainfall, mining site water depth, and slope soil moisture content changes; Underground installation of roadway water level sensors (with a water resistance pressure of 1.5MPa and an accuracy of ± 0.5cm) and water inflow meters (with a range of 0-500m ³/h and an accuracy of ± 2%) to dynamically monitor underground water accumulation and inflow; Surrounding areas are equipped with river water level stations (range 0-15m, accuracy ± 1cm) and mountain displacement monitoring devices (GNSS positioning accuracy ± 2.5mm) to predict external flood backflow and landslide risks, forming a multi parameter collaborative monitoring system of "rain situation water situation engineering situation danger". Compared with traditional single monitoring equipment, the warning dimension is increased by four times, and the warning advance time is extended to 2-4 hours, solving the fatal pain point of "late risk detection and passive disposal".
To ensure the accuracy of data in complex mining areas, the system has a built-in "mining area environment adaptive algorithm" to specifically solve the problem of special interference in mining areas: for high dust environments in open-pit mines, the rainfall sensor adopts a tipping bucket structure+automatic heating descaling module, and automatically starts ultrasonic cleaning every hour (water pressure 0.6MPa) to avoid measurement deviation caused by dust blockage. In mining areas with dust concentration exceeding 200mg/m ³, the measurement error is still controlled within ± 3%; In response to high humidity and strong electromagnetic interference underground (such as mining motors and frequency converters), the roadway water level sensor adopts an intrinsic safety design (explosion-proof mark Ex ib I Ma), and the circuit system adopts three-level electromagnetic shielding (shielding effectiveness ≥ 80dB). In an environment with a relative humidity of 95% RH and electromagnetic interference intensity of 100V/m, the fluctuation amplitude of data transmission is ≤ 0.1%; For highly corrosive water quality (including heavy metal ions and acid-base substances) in tailings ponds, the water level sensor probe is made of 316L stainless steel material and coated with polytetrafluoroethylene, which has a corrosion resistance five times higher than ordinary sensors. In tailings water with pH values of 2-12, the service life can reach more than 8 years.
In terms of warning function, the system supports a "multi-level warning+dynamic threshold" mechanism, and can customize warning parameters according to the risk level of different areas in the mining area: setting a first level warning for the tailings pond (highest risk) (water level exceeding 90% of the design flood level, infiltration line rising rate exceeding 5cm/d), triggering the start of flood discharge pumps and evacuating downstream personnel; Set up a second level warning for underground tunnels (high-risk) (water level exceeding the warning level, water inflow exceeding 120% of the design value), trigger the closure of the tunnel entrance, and activate the drainage system; Set up a three-level warning for open-pit mining sites (medium risk) with rainfall exceeding 50mm/6h and water accumulation depth exceeding 50cm, triggering the suspension of mining operations and dredging of drainage channels. All warning information is pushed through the mining area broadcasting system (with a volume of 120dB), the dispatch center screen, the mobile app, and SMS in four ways, with a response time of less than 10 seconds. At the same time, an emergency response plan is automatically generated (such as "Tailings Pond Level 1 Warning: Immediately start the 1 # -3 # flood discharge pumps and evacuate residents within 3km downstream"), guiding management personnel to handle quickly. In practical applications, the accuracy and reliability of the system have been fully verified. In the application of 18 systems in a large open-pit coal mine in Shanxi Province in 2025, a monitoring network was formed. During a heavy rainfall process, it was detected 3 hours in advance that the rainfall in the mining area reached 45mm/6h and the depth of accumulated water exceeded 40cm. The three-level warning was immediately triggered, and the coal mine suspended mining operations and started drainage pumps in a timely manner to avoid equipment flooding in the mining area (under traditional no warning situations, such rainfall can easily cause equipment damage and direct losses exceeding 5 million yuan); In the application of a tailings pond in Anhui Province, the system detected that the water level exceeded the warning value and the infiltration line rose at a rate of 8cm/d, triggering a first level warning. The enterprise immediately activated emergency response and evacuated more than 500 villagers downstream within 24 hours. Three days later, the tailings pond successfully discharged water without any safety accidents, fully reflecting the core advantages of "multi parameter collaborative monitoring and precise and efficient warning".
