Benefits of Diamond Wire Sawing for Stone Mining

Advantages of using diamond wire saw for stone mining Compared with the traditional blasting + flame cutting mining method, using diamond wire saw to mine granite has the following advantages:

1.Wire saws are versatile and can be used in various types of mines such as granite, marble, limestone, and sandstone. They cut hard materials effectively and are available for both straight and curved cuts. Flame cutting is only suitable for granite mines with high quartz content and few cracks.

2.Diamond wire saws are known for their high efficiency and powerful cutting capabilities.

Mining Depth: Diamond wire saws have the advantage of being able to cut to greater depths compared to flame cutting. This is especially beneficial when mining depths of more than 10-20 meters, as diamond wire saws can easily reach these depths.

Cutting speed: Diamond wire saws are known for their fast cutting speeds. They can typically achieve cutting speeds of 3-4 m² per hour, which is much faster than flame cutting (typically 2-2.5 meters per hour). Faster cutting speeds increase the productivity and efficiency of mining operations.

3.Diamond wire saw has versatile cutting capabilities and can cut in all directions – vertically, horizontally, and at an angle. flame cutting, on the other hand, involves using a high-temperature flame to melt or burn through the material and is usually limited to vertical cuts. This limitation is mainly due to the more challenging direction and control of the flame compared to a wire saw. Wire saws are often used in situations that require precision and dexterity, such as cutting concrete, stone, or metal structures. The ability to perform blind cuts is another advantage of wire saws. Blind cutting refers to cutting material where direct visibility is limited or obstructed. A jigsaw can be used to cut walls, foundations, or structures without being hampered by a lack of direct visibility.

4.The smooth cutting surface of the wire saw helps minimize internal damage to the scrap. This is especially important when cutting materials with sensitive internal structures, such as certain metals or delicate stones. The smooth cutting surface reduces material loss, which increases the yield of usable workpieces. In addition, the small kerf of approx. 11 mm in the wire saw helps prevent resource waste. A narrow kerf means less material is removed during the cutting process, reducing overall waste. This is especially advantageous when using expensive or valuable materials. In contrast, flame cutting results in a rough and uneven cut surface that can cause internal damage to the scrap. Such damage may reduce the usability or value of the material and result in additional losses. In addition, the large kerf, typically 100-300mm in flame cutting, results in a serious waste of resources. A wider cut removes more material than a wire saw, resulting in higher material loss. This can increase mining costs as more raw materials are required to compensate for wasted resources. Given the smoother cutting surface, smaller kerf, and reduced waste, wire sawing can provide higher throughput and lower overall costs than flame cutting in a variety of applications.

5.Wire saw mining offers a safer and more environmentally friendly alternative to flame cutting. There is no noise and dust generated by wire saws, providing a better working environment for nearby residents and workers. In addition, the high degree of automation, individual controls, and low labor intensity associated with wire saw mining contribute to increased productivity and efficiency. In contrast, the flame-cutting method is known to generate a lot of noise and dust, which can negatively affect the well-being of nearby residents and workers. Compared to wire saw mining, the labor intensity involved in flame cutting is generally higher and the required safety measures may be relatively low. Additionally, with the resource becoming increasingly scarce and oil prices rising, wire saw mining offers a more cost-effective and sustainable method of mining granite. It minimizes resource consumption while providing economic and social benefits to the mining industry. Overall, considering the advantages of safety, environmental protection, labor intensity, and economic sustainability, wire saw mining is the preferred method for granite mining.
