Low production rate, limited recovery range, and short period of stabilized production of
natural gas hydrate (NGH) field trials indicate a large gap to commercial production. To …

Water and mud inrush is one of the most important geohazards in underground engineering.
The paper presents a state-of-the-art review of the current understanding of this type of …

Quick-setting grout has been widely used in sealing underground excavations to prevent
water ingress. Cement and sodium silicate grout (C–S grout), a typical quick-setting slurry, is …

Fire prevention with inorganic gel is the most efficient approach to the prevention and control
for spontaneous fires of loose coal piles. This work explores the impact of grouting pressures …

Quick setting slurry is commonly used in rock fissure grouting projects due to short gel time,
high early strength and high retention rate in groundwater. Generally, quick setting slurry is …

Fracture grouting is one of the most widely used methodologies to reduce the hydraulic
conductivity and enhance the strength of rock masses in geotechnical engineering (eg …

The stratification split grouting foam mortar method (SSGFM) was first proposed to stimulate
the low-permeability gas hydrate reservoir through constructing the fast flow channel for …

A two-dimensional grouting model considering hydromechanical coupling and fracturing in
fractured rock is proposed and implemented in an GPU parallel multiphysics finite element …

It is difficult to temporally and spatially track and characterize the slurry viscosity in flowing
water during grouting simulation. In this study, a sequential flow and solidification (SFS) …

In this paper, we present a three-dimensional (3D) grouting model based on the combined
finite-discrete element method (FDEM). The 3D grouting model discretizes the problem …
