Description

technical field

[0001] The invention relates to the technical field of seepage simulation, in particular to a dynamic deformation soil seepage simulation device. Background technique

[0002] In recent years, there have been dozens of water inrush disasters caused by coal mining and underground engineering under loose aquifers, causing significant economic losses and serious social impacts. It can be seen that improving the recovery rate of resources and protecting water resources are the key issues to realize coal mining under water.

[0003] Considering the evolution characteristics of mining fissures in key water-resistant rock formations, under the action of seepage field and stress field, the key water-resistant formation system is a time-varying nonlinear seepage system. Whether seepage stability occurs after compaction and stability requires in-depth research and analysis. It is verified that the development height of a single water-conducting fracture zone cannot be...
