Abstract
[Objective]Water inrushes from floors are subjected to the superimposed effects of factors such as specific geological structures,water-rock-stress coupling,and mining disturbance,proving complex,concealed,and abrupt.[Methods]Physical simulation experiments can effectively reproduce the environments of the floors and confined water,intuitively present the whole process of both mining-induced fracture propagation in the floors and the path evolution of water inrushes,and obtain multi-source data of all disaster stages in a real time manner.Therefore,such experiments en-joy unique advantages in investigating water inrushes from floors.[Results and Conclusions]This study reviews the re-search achievements in water inrushes in terms of classical theories,standards and specifications,simulation experi-ments,and engineering practice,highlighting three advances in research:experiment loading devices and water pressure simulation methods;the R&D and characteristic indices of similar materials,and monitoring technologies and their ob-servation system design.A breakthrough has been made in capturing the whole-process information of water inrushes from floors using a 3D model under the simulated water-rock-stress coupling environment.In the broad context of re-search on digital intelligence,this study analyzes the limitations of physical simulation experiments on water inrush from floors.Accordingly,it proposes that future development should focus on the R&D of large-scale,comprehensive 3D ex-periment platforms for water inrush from floors,the establishment of a standardized database for multi-characteristic proportioning of similar materials,the construction of a multi-phase,multi-field,and multi-dimensional coupling monit-oring and early warning system,and the integrated application and research of digital intelligence technologies includ-ing artificial intelligence.The insights of this study will assist in improving the level of physical simulation experiments from the aspects of devices,materials,and technologies,thereby supporting the high-quality advancement in fundament-al research on the intelligent prevention and control of water hazards from floors in coal mines.
