Mine hydrological monitoring system: real-time perception of water conditions, building mine safety
Date: 2025-12-22Read: 8
During the mining process, hydrological disasters are one of the core risks that threaten operational safety. Groundwater surges, abnormal water levels, and other situations can easily lead to accidents such as collapse and seepage, causing significant casualties and property losses. Traditional mine hydrological monitoring relies on manual inspection, which has problems such as data lag, large measurement errors, and untimely risk warning, making it difficult to meet the refined needs of modern mine safety control. The mine hydrological monitoring system takes "precise monitoring, automatic warning, and remote control" as its core advantages, adapts to the complex and harsh environment of mines, builds a strong protective barrier for mine hydrological safety, and is widely used in underground water level measurement, mine deep water level measurement, geothermal well water level measurement and other scenarios.
The entire scene is designed to adapt to the complex environment of the mine. The mine hydrological monitoring system is designed for the harsh environment of high voltage, high humidity, high dust, and easy lightning strikes underground. It adopts multiple protection designs: the core sensor is equipped with a strong anti high voltage and high underground water level online monitoring system sealing chip, and the integrated structure is matched with triple lightning protection technology, which can effectively resist underground high voltage impact and lightning interference; The sensor is made of corrosion-resistant stainless steel material and equipped with a stainless steel protective box, which has excellent corrosion resistance and oxidation resistance. The waterproof level reaches IP66 and can operate stably in humid underground environments for a long time. The measurement range of the system covers multiple levels such as 100 meters, 200 meters, 300 meters, 400 meters, etc., which can adapt to the monitoring needs of deep well water level in mines at different depths. Whether it is shallow mines or deep mining areas, it can accurately capture water level changes.
Scientific measurement principles ensure accurate and reliable data. The system is designed based on the principle of static water pressure, using water pressure sensitive integrated components as the sensor probe of the deep well water level measuring instrument. When the probe is fixed at a measuring point underwater, by detecting the height of the water column pressure above the measuring point and combining it with the elevation of the measuring point, the water level height (the distance from the water surface to the wellhead) can be indirectly and accurately measured, and the actual height of the liquid level in the deep well above the probe can be directly obtained. To further improve data accuracy, the system adopts a core automatic correction algorithm, which can effectively prevent numerical fluctuations caused by water surface fluctuations; The probe is equipped with a sloping guide hole, which can effectively prevent the entry of silt impurities and resist the impact of water flow, avoiding measurement errors caused by probe blockage or damage. The signal transmission adopts tension resistant steel wire cables to ensure real-time, high-precision and stable output display of measurement signals in the complex wiring environment of the mine.
Intelligent automatic control, realizing risk early warning. The system has full process automatic monitoring function, without the need for manual on-site monitoring, greatly reducing the safety risks of underground operators. The power supply module equipped with a solar panel top cover embedded design has higher photoelectric conversion efficiency and increased wind resistance level. Coupled with an MPPT automatic power point tracking charging controller, the charging efficiency is improved by 20%, which can provide long-term stable power supply in remote mine areas without mains power coverage. The data transmission adopts RS485 signal output, with a maximum communication distance of up to 2000 meters. It supports remote data upload to the monitoring platform, and management personnel can view water level data and historical change curves in real time through computers and mobile phones. The system supports custom warning thresholds. When the water level data exceeds the safe range, the SMS alarm mechanism is immediately triggered to send warning information to designated management personnel's mobile phones, buying valuable time for emergency response.
Quality assurance and practical value safeguard mine safety. The system has complete safety protection performance, achieving reverse polarity protection and instantaneous overcurrent and overvoltage protection, meeting EMI protection requirements, and ensuring safe operation in complex underground circuit environments; Strong overload and anti-interference ability, economical, practical, stable and reliable. In the application of a large coal mine, the system detected an abnormal upward trend of underground water level 3 hours in advance, sent timely warning information, and the mine management department quickly initiated emergency drainage response, avoiding the occurrence of water leakage accidents; In deep mining projects, the system accurately monitors water level changes at a depth of 400 meters, providing reliable hydrological data support for optimizing mining plans and ensuring safe and efficient mining operations.
