Fragmentation characteristics and microscopic fracture mechanisms of magnetite rock under explosive impact after microwave irradiation

Key Points

• Fragmentation characteristics improve under explosive impact after microwave irradiation and reveal clear mechanisms.
• The study observes significant differences in fracture patterns, demonstrating varied responses based on treatment.
• Assessment using microwave irradiation on magnetite rock shows that explosive impact alters fragmentation effectively.
• These findings may enable better application of microwave techniques in enhancing rock fragmentation for mining.
