The decomposition of natural gas hydrate (NGH) will cause a decrease in reservoir strength,
which can easily induce submarine landslides when hydrate reservoirs are located on a …

Excessive floor deformation in underground coal mines, known as floor heave, can cause
production delays and thus financial losses. This paper presents parametric studies using …

The floor heave is one of the key factors that can restrict high‐efficiency and safety mining,
especially in the deep roadways with soft rock. Considering the influences of rock fracturing …

Several underground coal mines have reported floor heave associated with the buckling
mechanism. However, studies on the coal mine floor, especially the buckling failure …

Accurate assessment of the inverted arch's health status in tunnels is pivotal for preventing
floor heave and ensuring traffic safety. This study investigated the condition of inverted …

The phenomenon of the floor upheaval occurs in virtually every type of rock mass and at
every depth, accompanying the process of excavation of tunnels and headings. Despite its …

The stability of the surrounding rock is the key problem regarding the normal use of coal
mine roadways, and the floor heave of roadways is one of the key factors that can restrict …
