The Utilization of a Coupled Electro-Thermal-Mechanical Model of High-Voltage Electric Pulse on Rock Fracture

Weikang Feng et al.

Summary: Our research proposes a unique coupled electro-thermal-mechanical model that considers electric breakdown and heterogeneity to show the mechanism of rock fracturing under high-voltage electropulses. Using finite element numerical software, the process of high voltage electrical pulse injection into the rock interior for breakdown is described, and the formation law of plasma channels during the electrical breakdown process is comprehensively analyzed. The presented model contributes to a better understanding of the mechanism of rock fragmentation during high-voltage electrical pulses, which has substantial implications for oil exploration and mineral extraction.

The Fragmentation Mechanism of Heterogeneous Granite by High-Voltage Electrical Pulses

Xiaohua Zhu et al.

Summary: This study investigates the fragmentation mechanism of high-voltage electrical pulses (HVEP) in rock-breaking and finds that a finer grain size of granite leads to better crushing degree of HVEP. Additionally, the length of the plasma channel is positively correlated with the energy efficiency of HVEP. These research findings have significant implications for the engineering application and design of HVEP.
