Rock failure phenomena, such as rockburst, slabbing (or spalling) and zonal disintegration,
related to deep underground excavation of hard rocks are frequently reported and pose a …

Cleaner production is the continuous application of an integrated preventive environmental
strategy which stressed the importance of environment and human beings. Although the …

To comprehensively understand the differences in mechanical behavior of coal during the
mining process at different depths, cyclic triaxial loading and unloading (CTLU) experiments …

Based on the relationship between rockburst and microseismic event indicators, this study
proposes that the risk of rockburst in mine working faces, roadways, and even the entire …

The variation of the in situ stress state is closely related to various factors. In situ stress state
is also an important indicator to guide mining production. The study of in situ stress …

To analyze and predict the mechanical behaviors of deep hard rocks, some key issues
concerning rock fracturing mechanics for deep hard rock excavations are discussed. First, a …

Large deformation of soft rock roadway has always been a major difficulty in deep mining
practices. This paper describes a case study of the failure mechanisms and stability control …

The mechanical behavior of coal is the key factor affecting underground coal mining and
coalbed methane extraction. In this study, triaxial compression and seepage tests were …

The utilization of deep mineral resources is severely restricted by dynamic disasters, such as
rock burst, caused by mining disturbances. This study is aimed at investigating the instability …

The surrounding rock in deep underground engineering is often subjected to true three-
dimensional high-stress conditions. Excavation unloading results in changes in the stress …
