Strong rockburst disaster in deep coal mines is easily triggered by the higher static stress of
mining coal seam and the dynamic stress wave disturbance generated by hard and thick …

Moisture-induced reduction in the strength of shales is one of the primary mechanisms of
roof degradation affecting the stability and safety of underground coal mines. The underlying …

Seismic events, ie, fractures in rock that radiate detectable seismic waves, are a worldwide
phenomena associated with mining and reservoir exploitation. Longwall mining in German …

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 …

Shear failure is a common failure mechanism in underground coal mine roadways. This
paper presents an innovative numerical approach to simulate shear failure of a coal mine …

Risks associated with unstable rocky slopes are growing as a result of climate change and
rapid expansions of human habitats and critical infrastructure in mountainous regions. To …

Uncontrolled and excessive gas emissions pose a serious threat to safety in underground
coal mining. In a recently completed research project, a suite of monitoring techniques were …

Erosion of rock cliffs has been considered to be relatively unpredictable. This perceived
stochastic nature of the erosional processes often occurs through collapses along fractures …

Coal burst has been increasingly attracting attention in Australian coal mines recently as
they go deeper. Coal burst is well known for its catastrophic destruction, complex …

We deployed seismic and infrasound sensors at a historically active cliff in Yosemite Valley
for the purpose of detecting and locating rock falls at local (< 1 km) distances and …
