WX-DSW4, Wanxiang Environment, Shandong Province, assists in multi field environmental monitoring. During coal mining, hydrological safety is of paramount importance in ensuring operational safety. Accidents such as groundwater surges and old air water seepage have strong suddenness and great harm, and once they occur, they will cause significant losses. Traditional coal mine hydrological monitoring methods have problems such as limited monitoring range, data lag, and weak anti-interference ability, making it difficult to adapt to the complex environment of high pressure, high humidity, high dust, and easy lightning strikes underground in coal mines. The coal mine hydrological monitoring system is tailor-made for coal mine scenarios, with the core advantages of "scene adaptation, precise monitoring, and rapid warning", providing water safety protection for coal mine hydrologyData support is widely used in scenarios such as deep well water level measurement in coal mines, hydrological monitoring in mining areas, and boundary water level monitoring in mining fields.
Specialized adaptation for coal mine scenarios to withstand complex environments. The system is specially optimized for the harsh environment underground in coal mines, with core sensors built-inAnti high voltage sealed chip, integrated structure with triple lightning protection technology, can effectively resist underground high voltage impact and lightning interference, ensuring stable operation in complex electromagnetic environments. The sensors and protective boxes are made of anti-corrosion stainless steel materials, which have excellent corrosion resistance and oxidation resistance. The waterproof level reaches IP66, and can withstand long-term corrosion from underground humid environments and coal mine wastewater; The probe adopts a slope type liquid guide hole design, which can effectively prevent impurities such as silt and coal slag from entering the coal mine underground, avoid probe blockage, and have the ability to resist water flow impact, ensuring measurement continuity. The measurement range covers 100-400 meters and can adapt to the water level monitoring needs of deep mines and goaf areas at different depths.
Accurately capturing water conditions and mastering hydrological dynamics. The system is based on the principle of hydrostatic pressure and uses a diffusion silicon piezoresistive sensor probe for input measurement. By detecting the water column pressure at the underwater measuring point, the water level height (distance from the water surface to the wellhead) is accurately calculated, and the actual height of the liquid level is directly obtained. The application of core automatic correction algorithms effectively offsets numerical fluctuations caused by factors such as underground water flow fluctuations and ventilation disturbances, ensuring the accuracy of monitoring data. The signal transmission adopts tension resistant steel wire cable, which hasTensile and wear-resistant performance, able to adapt to the complex wiring environment underground in coal mines, ensuring real-time and stable transmission of measurement signals to the monitoring center; Supports RS485 signal output, with a maximum communication distance of up to 2000 meters, and can cover a wide monitoring area of large coal mines.
Intelligent warning linkage, quick response to risks. The system has a comprehensive intelligent warning function, and management personnel can customize water level warning thresholds for different areas on the monitoring platform (such as the upper limit of water level in mining areas and the boundary water level warning line of wellfields). When an abnormal rise or fall in water level is detected, the system immediately triggers a SMS alarm mechanism, sending warning information to designated personnel such as coal mine safety management personnel and underground operation managers on their mobile phones. At the same time, warning prompts pop up on the display terminals of the ground monitoring center and underground operation points, achieving a coordinated linkage of "ground docking+underground response". For remote monitoring points without mains power coverage, the system is equipped with a solar panel cover embedded power supply module, which has high photoelectric conversion efficiency and strong wind resistance level. The MPPT automatic power point tracking charging controller improves charging efficiency by 20%, ensuring 24-hour uninterrupted operation of the system and avoiding warning delays caused by power outages.
Highlighting practical value and safeguarding coal mine safety. In a monitoring project of a large coal mine mining area, the system detected an abnormal rise in water level in the goaf 2.5 hours in advance, promptly sent warning information, and the coal mine immediately activated the emergency response for water seepage, organized the evacuation of underground workers, closed relevant mining faces, and avoided major water seepage accidents; In the monitoring of coal mine boundaries, the system monitors water level changes for a long time, effectively preventing the risk of external groundwater backflow; In the monitoring of the old empty water area, accurate capture of water level dynamics provides reliable data support for the development of old empty water drainage plans. The application of the system has greatly improved the precision level of hydrological monitoring in coal mines, and built a strong hydrological protection barrier for safe mining in coal mines.
