峰后岩石非Darcy渗流中的孤波
Solitary waves in non-Darcy flow in post-failure rock
摘要
Abstract
The dynamical equations of non-Darcy flow in post-failure rock are an important model for the study on dynamic disaster caused by coal mine water inrush,coal and gas outburst,etc.Once solitary waves manifest in non-Darcy flow within post-failure rock,they may induce instability in the flow dynamics of the rock mass,potentially resulting in safety incidents such as water inrush or coal and gas outbursts.The modified tanh-coth method is applied to the dynamical equations of non-Darcy flow in post-failure rock,and some new periodic and soliton solutions of the equations are obtained.The results are helpful to further study the solitary waves in non-Darcy flow in post-failure rock,to provide theoretical basis of designing efficient measures to control the disasters corresponding the solitary waves.关键词
