Large and super-large section chamber groups in coal mines are frequently affected by
dynamic loads resulting from production activities such as roadway driving and blasting. The …

Layered filling is easy to lead to layered structure of cemented paste backfill (CPB). To
understand the mechanical behavior, failure modes, and damage evolution of layered …

This study presents a comprehensive field investigation of the ground response of a
gateroad subjected to high stress induced by extracting a 17 m-thick coal seam. The test site …

Underground coal mining activities cause redistribution of the stress and deformation fields
in surrounding rocks, resulting in different degrees of failure to the overlying strata above the …

Bolt is an important connection in underground construction and monitoring its stress
characteristics is essential to evaluate the effectiveness of bolt. The strain information …

Layered rocks exhibit notable transverse isotropy and have a significant impact on the
deformation and failure characteristics of underground structures. To a large extent, the …

In underground retreating longwall coal mining, hard roof collapse is one of the most
challenging safety problems for mined-out areas. Identifying precursors for hard roof …

This paper presents an integrated approach for field instrument and numerical modeling to
investigate the stability principle and control method of entries that are driven adjacent to a …

To ameliorate the defects of insufficient support resistance of traditional roadside filling
bodies for gob-side entry retaining (GER), overcome the inability to adapt to the deformation …

This paper endeavors to reveal the squeezing failure mechanism of roof‐coal masses and
its correlation with the movement of the roof strata. An integrated method incorporating field …
