The invention belongs to the technical field of coal mine early warning, and discloses a coal mine underground water prevention and control early warning system, a method and application, wherein the coal mine underground water prevention and control early warning system comprises the following steps: the advanced exploration and stope face water damage prediction system carries out coal mine water-containing structure and water guide condition detection and determines stope face water damage prevention and control technical measures; the underground water dynamic monitoring system acquires and analyzes corresponding data of underground water by using a mining area hydrological dynamic monitoring system; the mine water source rapid distinguishing system is based on existing mine data, adopts geophysical prospecting, drilling and chemical prospecting methods to carry out chemical examination and analysis, determines the water chemistry background characteristics of a mine area, establishes a mine area water chemistry database, establishes distinguishing models of water quality of different aquifers in a well field and rapidly distinguishes various water burst sources. The invention can predict and early warn the water inrush of the mine in time, and can purposefully take water prevention and control measures, thereby ensuring safe, economic and reasonable production of the mine and comprehensive utilization of water resources. |
