An experimental system for crushing coal by applying high-voltage electrical pulses was developed.
- class="label">•
The degree of coal fragmentation increases with the increase of breakdown voltage.
- class="label">•
The higher breakdown voltage attributes to the generation of more pores and fractures in coal samples.

The effect of high voltage on macropores is more remarkable than other types of pores.
