Characterization of the susceptibility of ore particles to breakdown in high voltage pulse breakage and the influencing factors
The susceptibility of ore particles to electrical breakdown plays a critical role for high voltage pulse (HVP) breakage, yet its quantitative characterization still lacks deep understanding. Two indicators, namely breakdown delay time (Td) and breakdown strength (Eb) were compared, based on…

Long-term creep of Beishan granite under uniaxial compression
Investigations into the long-term creep behavior of Beishan granite in uniaxial compression were conducted. Four levels of axial stress (60, 70, 87, and 95 MPa) were applied to rock specimens. Contrasting with earlier research, the long-term creep data in this work present a substantial advancement…
