[0002] At present, many mines have gradually entered the deep mining stage. The practice of deep mining shows that compared with shallow mining water hazards, deep mining presents two major characteristics: "high pressure and weak water-rich" and "delayed large-scale water inrush". It is of great theoretical and practical significance to study the characteristics of water occurrence in deep mines, deepen the technical methods of water hazard prediction and evaluation, and clarify the key directions of deep mine water hazard exploration and implement integrated exploration technology for precise investigation and treatment of water hazards on this basis. When mining coal seams under deep high-pressure aquifers, when the overburden mining cracks affect the aquifer, the water inflow from the working face increases instantly. In severe cases, water inrush accidents may occur, resulting in equipment damage and even casualties, causing huge economic losses. How to effectively drain the "high-pressure and weak water-rich roof aquifer" is the key to preventing and controlling roof water hazards.
