Rockburst in Sandstone Containing Elliptic Holes with Varying Axial Ratios
Advances in Materials Science and Engineering, 2019 Rockburst disaster is one of the prominent problems faced by deep underground engineering. In this study, rockburst in four elliptical holes with different axial ratios in sandstone under biaxial loading is studied as an analogue for underground roadways.
