Abstract: The hydrological monitoring system of water-rich mines in China still has shortcomings in information collection，monitoring range and real-time performance. Taking a water-rich iron mine as the background，based on GPRS data transmission and network transmission technology，combined with the actual mine construction，a set of hydrological on-line monitoring and early warning solutions integrating surface and underground is proposed. The scheme includes surface hydrological drilling automatic teleme⁃ try early warning system and underground hydrological online monitoring early warning system. It is also proposed that in the process of mine production，the advanced drilling and geophysical prospecting technol⁃ ogy should be combined to realize the water exploration and drainage in the rake direction of the working face，and the water exploration hole with large water volume should be used as a long-term drainage hole to install monitoring and sensing equipment to realize the flexible expansion of the system. Through the re⁃ al-time dynamic monitoring and safety warning of hydrological parameters such as mine hydrological drill⁃ ing，underground channel flow，drainage pipeline flow，pipeline pressure，underground water level，etc.， timely grasp of groundwater dynamics and safety control.
