Rockburst is becoming a huge challenge for the utilization of deep underground space.
Extensive efforts have been devoted to investigating the rockburst behavior and mechanism …

In this paper, triaxial compression tests on coals with real-time T 2 and MRI (Magnetic
Resonance Imaging) image measurement are performed by using a nuclear magnetic …

The dynamic evolution characteristics of fractures in coal under different compressive loads
are of great significance to the recovery of coalbed methane (CBM). In this paper, the X-ray …

The fractal characterisation of stress and acoustic emission (AE) of coal and rock failure may
provide quantitative guidance for analysing the stability of rock mass during excavation …

The availability of high-accuracy altimetry and satellite gravity data leads to the development
of high-resolution global gravity model data. It helps in understanding the structure and …

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 …

Massive coal extraction from the longwall panel results in the formation large void space
(goaf), which is followed by elevation in the stress level of the overlying strata. The …

Global coal deposits are often associated with trapped methane, whose nature and
composition are similar to that of the natural gas. Compared to coal, this trapped methane is …

The quality of borehole sealing has significant influence on the gas extraction. Inorganic
sealing material has the advantages of low cost, multiple functions and high performance; …

Mining of coal has always been a very risky task from older times and, is often associated
with various fatal accidents in form of rock bursts, gas outbursts, slope/bench failure. Studies …
