Reasonable coal pillar size of roadway protection is an important guarantee for roadway
stability under the action of static-dynamic coupling loadings in deep mines. Coal pillar and …

The reasonable size of the coal pillar in the working face is usually the most critical aspect in
coal mining, which is related to the deformation of the surrounding rock of the roadway and …

The key to the selection of coal pillar width lies in the stability of the roadway space and the
stability of the coal pillar itself. Based on the theory of coal pillar stress distribution, the …

Long-term stability of the protective coal pillars in coal mines can ensure normal and safe
use of roadways; in turn, the integrity of the roadway plays an important role in safe and …

The fracturing behaviors of serial coal pillars is significant for understanding their failure
mechanism. To reveal this, the bearing stress, acoustic emission, electrical resistivity, local …

Accurately distinguishing the stability of the residual coal pillars formed by the room-and-
pillar mining method is significant for the safe mining of adjacent coal seams. In this study …

Accurately distinguishing the stability of the residual coal pillars formed by the room-and-
pillar mining method is significant for the safe mining of adjacent coal seams. In this study …

The supporting technology of retaining small coal pillars in a double roadway layout can
effectively relieve the tension of mining and excavation replacement and improve the coal …

Coal pillar is a crucial element formed during underground coal mining, playing a significant
role in ensuring coal mining operations are conducted safely. Historically, research on coal …

As the depth of coal seams increases and the demand for coal grows, the deformation and
failure of roadways and coal pillars also intensify. To address the instability of roadways, it is …
