Abstract 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 mechanisms and difficulty of control in the mining industry. This paper summarises the control measures used globally for this dynamic failure, and shows how to develop ...

Models of translatory rock bursting in coal
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1981Abstract A model material and a model technique have been found which show, in laboratory tests, the typical features of translatory rock bursts (bumps) in coal mines. The qualitative observations made using the model, agree with theoretical predictions published earlier.

Bursting liability indices of coal
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1981Abstract Natural coal's ability to store and release rapidly elastic strain energy seems to be a fundamental condition for the occurrence of rock-bursts in deep underground coal mines. In Upper Silesia where a number of existing mines work below a critical depth, several indices have been proposed and their numerical values found by experiment in ...

An overview of research into understanding coal burst
2019Coal burst is a high safety and production risk in underground coal mines. It involves a sudden release of strain energy stored within the coal or rock mass due to the disturbance of an unstable state of equilibrium. To improve our understanding of coal burst, it is important to quantify the energy transition involved in this dynamic failure process ...

Field Monitoring of Delayed Coal Burst in an Advancing Entry of a Deep Coal Mine
Mining, Metallurgy & Exploration, 2021Delayed coal bursts in deep coal mines have caused significant fatalities and economic losses in recent years. Instead of occurring right around the advancing face, this particular type of coal burst is characterized by its occurrence at a certain distance behind the advancing face.

After rock burst and spontaneous combustion, a coal seam is exposed, and this form of compound disaster shows new characteristics. Therefore, basic research on oxidized coal is important to the theoretical research and prevention of compound disasters.

Investigation of Coal Burst Potential Using Numerical Modeling and Rock Burst Indices
2021Coal bursts are typically defined as a rapid failure of coal or surrounding rock producing a violent release of energy and ejection of rock particles. This phenomenon is extremely complex and dynamic, and this has made it very difficult to predict. In the last decades, different researchers have aimed to understand the sources and mechanisms of failure

Steady advance of coal and gas bursts
Acta Mechanica Sinica, 1988This paper establishes a one-dimensional model to analyse the mechanism of coal and gas bursts. It is found that the intrinsic factor governing bursts is the coupling of the initiation of the moving of coal fragments with the gas seepage. A typical (strong) burst can be treated as a steady advance process.
