Compared to traditional extraction methods like blasting or flame cutting, using diamond wire saws for stone quarrying offers the following advantages:
1. Broad applicability: Wire saws are suitable for all types of quarries, whereas flame cutting is limited to granite quarries with high quartz content and few fissures.
2. High capability and efficiency: First, they allow for greater extraction depths—reaching 10–20 meters or more—while flame cutting is generally limited to depths of less than 10 meters. Second, cutting speeds are faster, typically ranging from 3 to 4 m?/h, which is two to three times that of flame cutting.
3. Versatile cutting angles: Wire saws can cut in various directions—including vertical, horizontal, and inclined planes—and perform “blind cuts,” whereas flame cutting is restricted to vertical surfaces.
4. High block yield and low overall cost: First, wire saws produce very smooth cut surfaces without causing internal damage to the stone blocks; second, the kerf (cut width) is narrow—only about 11 mm—minimizing resource waste. In contrast, flame cutting results in rough, uneven surfaces and causes internal damage to the blocks; the wide kerf (typically 100–300 mm) leads to significant resource waste and higher extraction costs.
5. Safety and environmental friendliness: Wire saw extraction generates no noise or dust, causing no disturbance to nearby residents or other work areas. It features a high degree of automation and remote control capabilities, resulting in lower labor intensity and higher safety for workers. Conversely, flame cutting generates excessive noise and dust, severely affecting nearby residents and other workers, while also involving high labor intensity and relatively lower safety levels.
In summary, given today’s context of increasingly scarce resources and soaring oil prices, using diamond wire saws for stone quarrying delivers significant economic and social benefits.
