Investigation Of Coal Burst Potential Using Numerical Modeling And Rock Burst Indices, Cristian David Cardenas Triana

Theses and Dissertations--Mining Engineering

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 of coal bursts. Various indices have been developed to assess the burst potential such as the Burst Potential Index (BPI), Energy Storage Rate, and the Strain Energy Density. Lately, numerical modeling has also been used as a tool to examine the rock deformation …
