An experimental study on the seepage characteristics of sandstones with different numbers of fractures before and after grouting

An experimental study on the seepage characteristics of sandstones with different numbers of fractures before and after grouting

BackgroundGrouting in surrounding rocks serves as a conventional approach to controlling disasters in coal mine roadways. The developmental degree of fractures significantly influences the reinforcement and sealing effects of grouting. MethodsTo determine the changes in the impermeability of fractur...
