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 …

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 …

Investigating the diffusion law of slurry while grouting in fractured aquifer is of great
significance to the safety in coal mining. In this paper, we comprehensively studied the slurry …

The coupling effect of a slurry and the fractured rock layer controls a spatial attenuation of
the fracture channel width and grouting pressure from a grouting hole to the slurry top of …

In view of the fact that the theory of fracture grouting in deeply buried rock strata seriously
lags behind engineering practices, a circular fracturing diffusion model of a single fracture …

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 …

To study the effect of a dominant fracture and slurry viscosity on slurry diffusion in a fracture
network, a dynamic water grouting simulation experimental device for fractured rock masses …

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 …

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 …
