Evaluation of current coal burst control techniques and development of a coal burst management framework

Tunnelling and Underground Space Technology, 2018
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 ...

A new seismic-based strain energy methodology for coal burst forecasting in underground coal mines

International Journal of Rock Mechanics and Minings Sciences, 2019
Coal burst has become a common safety issue in underground coal mines and its triggering mechanism is believed to be highly associated with coal state parameters including stress, strain and energy.
