Strata behaviour during the operation of super great mining height (SGMH) longwall face is
different from that of normal mining height due to the extra large boundary of caved roof …

This work aimed at revealing the mechanism of strong ground pressure behaviour (SGPB)
induced by high-position hard roof (HHR). Based on the supporting structures model of …

Earlier, an analysis of in situ observations at different sites of Indian coalfields was made to
visualize the development of mining induced stress over the coal pillars facing goaf line. An …

Catastrophic landslides have occurred frequently in the karst areas of Southwestern China
for these years, which makes it urgently necessary to reveal their triggering mechanisms …

Dynamic loading events in the longwall faces under slopes in the Shendong Coalfield,
China, seriously limit the safety and efficiency of mining. The slope characteristics, such as …

Underground coal mining leads to fracture and movement in the overburden and the
occurrence of weighting events in stopes. There are certain key strata that play an important …

Ore mining under the open-pit final slope will result in caving and large displacement
movement of rock-masses surrounding the goaf. It is difficult for numerical methods that …

Underground mining under an open-pit slope results in movement and instability of rock
masses. However, most rock mass movement prediction methodologies are empirical and …

In-situ investigations are the most direct and authentic approach for determining the law of
strata movement. In this study, in-situ investigation was carried out to determine the law of …
