... find mitigation measures for rockbursts. Recently, an M2.8 rockburst occurred in the mining drive at 1440 meter level underground on 16 January, 2018. In order to understand the mechanism of the rockburst, three major steps were taken. These were field geotechnical investigation, followed by uniaxial...
