FAQ: Key Parameters for Selection of Mining Machinery

Q1: How to select the scraper model according to the mine conditions?
A: Consider the tunnel cross-sectional dimensions (width × height), gradient, rock hardness (Mohs hardness ≤ 6.5), and daily work volume. For instance, tunnels with cross-sections less than 2m × 2m and gradients less than 15° should prioritize the use of sliding scraper machines; large cross-section inclined shafts require crawler machines with high gradients.

Q2: How do electric vehicles and battery-powered vehicles adapt to different transportation scenarios?
A: Trolley tractors for overhead lines are suitable for heavy-duty transport on fixed tracks over long distances (>1km) with low operating costs; battery-powered vehicles are ideal for flexible operations over short distances (<500m) with frequent starts and stops, without overhead line constraints but require consideration of charging facility layout.
