Under the condition of the shallow coal seam, the laws of roof activity after large mining
height longwall face mining and prevention measures for large-area roof weighting are …

The wide pillars are generally popular due to the high productivity and efficiency in
Northwest China. The distribution of lateral abutment pressure in coal pillars is important for …

Identification of precursory characteristics is a key issue for rock burst prevention. The aim of
this research is to provide a reference for assessing rock burst risk and determining potential …

This work aimed at revealing the mechanism of strong ground pressure behaviour (SGPB)
induced by high-position hard roof (HHR). Based on the supporting structures model of …

Understanding the mechanical properties and fracturing behaviours of coal is significant for
the safety of underground mining engineering. Coal failure characteristics are highly …

Thick hard rock strata (THRS) are widely distributed among coal-bearing strata in China.
The dynamic THRS failure may induce the coal-rock dynamic hazards during underground …

The long-term deformation of the Jinshandian Iron-ore Mine in China was monitored in situ,
and the failure characteristics of the underground roadways and ground surface were …

The conventional model for bearing structures was established based on the assumption
that the effect of unconsolidated layers can be assumed to be similar to uniformly distributed …

Rock bursts frequently occur in steeply inclined and extremely thick coal seams (SIETCS),
posing severe challenges to safe mining. To reduce the risk of rock burst in SIETCS, this …

An increasing number of mines in China are being subjected to overall-instability-induced
(OII) rockbursts in extracting deep remnant island longwall panels, causing severe damage …
