In this study, the low-field nuclear magnetic resonance (NMR) testing technique was
adopted to experimentally investigate the seepage processes of chemical grout flow in …

Investigations of the flow and diffusion mechanism of grout slurry in underground fractured
rock mass are of critical significance to guarantee the grouting reinforcement of deep soft …

Due to the invisibility and complexity of underground engineering rock masses, it is
extremely difficult to observe the diffusion process of dynamic water grouting. Therefore …

Investigation of the seepage characteristics and the corresponding repairing effects of slurry
on fractured rock mass is of great significance to grouting theory and operation parameters …

In this study, several chemical grouting tests of fractured porous sandstone were performed
based on the low-field nuclear magnetic resonance (NMR) technology, and the nuclear …

Modeling of cement grout flow in rock fractures is important for the design, monitoring and
execution of rock grouting that is widely used in a variety of rock engineering applications …

The massive mechanized and irrational coal mining has generated many goafs (ie, mined-
out areas) in China. To manage these goafs effectively, grouting technique has been …

It is of great theoretical significance and engineering application value to research the
diffusion law of slurry in mining fractures of rock strata to enrich grouting theory and improve …

The groundwater seepage in the fractured rock mass affects the stability of the surrounding
rock of the roadway. To understand the fluid seepage characteristics and the change law of …

Although grouting has been widely used in tunnels to seal groundwater inrush and reinforce
rock masses, dynamic water grouting in fractured rock remains challenging. Carbon fibre …
