Research Review on Water Inrush Mechanism and Failure Criterion of Rock Mass in Deep Mines

For underground deep mines, mining activities often cause mining disasters such as rock burst, roof fall and water inrush. Especially for underwater mines in the fault zone, surrounding rock instability and water inrush are the main threats to mining safely and efficiently. This paper briefly reviews the research progress and development trend of deformation law and failure mechanism of jointed rock mass specimens, multi-field coupling numerical simulation method of rock mass with faults, prevention of water inrush. Geological tectonic movement and rock mass excavation destroy the integrity and continuity of rock, break the in-situ stress field of rock mass, and lead to weak structural planes such as joints, cracks, and faults. The stress and strain properties of rock mass reflects the mechanical effects of rock mass and joints comprehensively. The physical, chemical, and stress environments of rock masses in deep mines are more complex. The mechanism of rock failure and water inrush disaster under the coupling effect of THMC multiple fields is worth further research. By combining CT scanning technology, digital core construction, and 3D printing technology, a digital core model and repeatable rock specimens can be constructed to study the mechanical properties and permeability evolution mechanism of jointed rock masses. According to the development of 5G technology and artificial intelligence technology, 5G technology is integrated into the monitoring, early warning, and emergency disposal of water inrush disaster.
