Due to high metal prices and increased difficulties in finding shallower deposits, the
exploration for and exploitation of mineral resources is expected to move to greater depths …

In this study, the tomography of dynamic stress coefficient (TDSC) was established based on
a mechanical model of stress wave propagation in bedding planes and a mathematical …

The rockburst in mines results from the dynamic load coupled with static one in coal seams
around workface zones, so it is essential to learn the stress distribution of the coal and …

The relation between applied stress and wave velocity is examined firstly at the laboratory-
scale by using ultrasonic technique. Subsequently, an island longwall face under hard-thick …

A better understanding of geological structures, stress regimes, and rock burst risks around
longwall mining panels can allow for higher extraction efficiency with reduced safety …
