Energy Consumption Assessment of Percussive-Rotary Drilling in Hard Rock Massifs Based on Specific Fracture Energy

Percussive-rotary drilling is widely used for excavation in hard rock massifs, yet it suffers from high energy consumption and low efficiency. This study presents a comprehensive assessment of energy consumption in percussive-rotary drilling based on specific fracture energy as the key metric. Laboratory experiments...

Dementalization of Underground Mine Roadway Support Systems Using GFRP Structural Elements

This paper addresses the critical issue of high metal intensity and corrosion degradation in underground mine support systems by introducing an alternative non-metallic solution. The research proposes a low-metal-intensity combined dual-level rock bolting system where traditional steel SVP-19 profiles and retaining p...
