Experimental study on the effects of electrode materials on coal breaking by plasma

AFM characterization of physical properties in coal adsorbed with different cations induced by electric pulse fracturing

“…7), demonstrating that high-rank coal is more sensitive to adsorb different valence cations than medium-rank coal. When the electric field is applied to both ends of coal sample, the plasma channels in coal generate huge energy, resulting in the temperature rise of pore-fracture and throat [65,66]. This not only affects the functional groups in coal but also generates large expansion stress, which makes the coal fracture under the action of the shock wave [61].…”
