The ancient blast-type mining has serious environmental damage and waste of resources. At present, the most popular mining method is diamond wire saw rope mining.
With the localization of diamond wire saw rope, the market competition for diamond wire saws suddenly became fierce. The emergence of this phenomenon indicates or represents that the era of the popular use of diamond wire saw machines in Chinese stone mines has come, which will bring revolutionary progress to the improvement of China's stone mine mining level. Compared with the traditional blasting flame cutting mining method, mining granite with diamond wire saw has the following advantages:
1. Wide adaptability, diamond wire saw is suitable for all types of mines, while flame cutting is only suitable for granite mines with high quartz content and few cracks.
2. Strong function and high efficiency. First of all, the mining depth is deep, which can reach 10-20m or even deeper, and flame cutting is generally only within 10m. Secondly, the cutting speed is fast, generally reaching 3-4m2/h, which is 2-3 meters of flame cutting times.
3. The diamond wire saw can perform vertical, horizontal, oblique and other cutting in all directions, and it can also perform blind cutting, while flame cutting can only perform vertical cutting.
4. The yield is high and the overall cost is low. First, the cut surface of the wire saw is very flat and will not cause any internal damage to the block material. Second, the sawing gap is small, only about 11mm, which will not cause waste of resources. While the flame cutting surface is rough and uneven, and It causes certain internal damage to the block, and the saw gap is large, generally 100-300mm, resulting in a great waste of resources and high mining costs.
5. Safe and environmentally friendly, diamond wire saw mining has no noise and no dust, does not affect nearby residents and other operating surfaces, and has a high degree of automation, separate control, low labor intensity and high safety. While flame cutting noise and dust are very large, it will seriously affect the operation of nearby residents and other workers, and the workers are labor-intensive and relatively low in safety. To sum up, in today's increasingly scarce resources and soaring oil prices, mining granite with diamond wire saw has significant economic and social benefits.
