Models of translatory rock bursting in coal

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1981
Abstract 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.

Investigation of Coal Burst Potential Using Numerical Modeling and Rock Burst Indices

2021
Coal 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

Deep Mining Optimization of Rock Burst Mines

Applied Mechanics and Materials, 2013
To prevent threaten of impact disaster, high-pressure water is injected into coal face, which is most widely used in impact-type mine. In such cases, by analyzing the rock burst tendency of a particular type of deep mining pit and occurrence of the mining process, rock samples drilled from the coal mine were taken for the conventional mechanical ...
