The KJ1165 Mine Hydrological Dynamic Monitoring System is an integrated, real-time, multi-parameter hydrological monitoring system designed for coal mines. It is primarily used for comprehensive dynamic monitoring of major water-bearing aquifers, water inrush points, inflow and outflow rates, underground water reservoirs, and surface meteorological conditions. It enables real-time, precise monitoring of water levels in major aquifers within the mining area and the dynamic patterns of inflow rates at different levels of the mine, providing a reliable basis for scientific decision-making regarding mine water control. This system offers four key advantages. First, it employs an integrated mine-surface architecture to achieve comprehensive coverage and synchronized monitoring of underground hydrological parameters and surface meteorological data; Second, it supports integrated monitoring of multiple parameters including water level, flow rate, water pressure, water temperature, and rainfall, with high data acquisition accuracy and strong real-time capabilities; third, it employs stable and reliable wired/wireless transmission modes, ensuring seamless connectivity between underground substations and the ground platform with stable, uninterrupted data transmission; fourth, it is equipped with specialized hydrological analysis software that enables real-time data display, trend analysis, anomaly alerts, and automatic report generation, providing digital support for water control decision-making.
