In recent years, the depth, intensity and complexity of coal mining in China has continued to
increase. Meanwhile rockburst disasters, especially fault-slip bursts, have become even …

In the mining process of close distance outburst coal seams, a large amount of gas is
desorbed and discharged into the atmosphere causing the waste of coal bed gas resource …

Earthquakes have always attracted civil and geotechnical engineers' attention, especially
when it comes to the liquefaction potential of soil. This paper investigates the feasibility of …

This study presents a comprehensive field investigation of the ground response of a
gateroad subjected to high stress induced by extracting a 17 m-thick coal seam. The test site …

To increase the recovery rate of coal mining operations, the gob-side entry retained (GER)
technique has been extensively implemented in China. However, due to the mining-induced …

Faults are one of the most common geological structures in underground mining. Affected by
mining activities, fault-slip events will release large amounts of energy and trigger seismic …

A new rockbolt test system was developed to investigate the dynamic response of
prestressed rockbolts. The test system involved the modification of a split Hopkinson …

A thorough excavation of the deep ultra-thick mines is highly challenging in rock
engineering, which mainly depends on the rheological properties of coal-rock mass, high …

Overlying key strata are regarded as plane-strained beams sandwiched by the soft rock
strata in the up and down directions, and are considered elastic media. Based on the theory …

The effects of low temperature and strain rate on the dynamic mechanical properties of dry
and saturated siltstones under sub-zero temperatures were investigated and presented in …
