In coal mining, coal seams often contain several normal coal layers and deformed coal
layers in the same region. However, the existence of deformed coal may promote the …

To investigate the dynamic mechanical properties and failure characteristics of the
surrounding rock mass in layered strata, composite specimens with a circular hole and a …

The Messinian salinity crisis (MSC)-the most abrupt, global-scale environmental change
since the end of the Cretaceous–is widely associated with partial desiccation of the …

In the field of rock engineering, the anisotropic failure criterion plays a vital role in predicting
the strength of rocks with varying degrees of anisotropy. This study presents jointed rock as …

Stratified rock mass usually exists in sedimentary formation, composed of at least two
lithological units with different mechanical properties, which may cause numerous disasters …

The particulate discrete element method (DEM) can be employed to capture the response of
rock, provided that appropriate bonding models are used to cement the particles to each …

Flysch is a sedimentary rock consisting of a rhythmic alternation of hard (limestone,
sandstone, siltstone) and weak (marl, mudstone, claystone) layers. Because of the presence …

In the western mining area of China, mudstone-clay composite roofs are commonly found in
coal seam roadway. This kind of roadway surrounding rock has poor self-stabilization ability …

Composite rocks are easily encountered in a wide range of geotechnical construction
projects. Understanding their mechanical properties and failure modes is very important to …

To conduct a successful geomechanical characterization of rock masses, an appropriate
interpretation of lithological heterogeneity should be attained by considering both the …
