As we all know, China's stone resources ranks globally. In recent years, with the rapid development of people's living standards in the construction industry, stone has become more and more popular with people because of its unique natural properties. The market demand is increasing. With the former China's stone processing technology has been close to the world advanced level, but the stone mining technology is still lagging far behind the developed countries.

　　At present, China's mine mining mainly includes the following methods: blasting operation, flame cutting method, and expansion agent method. The mining methods generally have the disadvantages of low labor productivity, low product rate, serious waste of resources, and poor safety. In recent years, some companies have used diamond bead wire saws and diamond chain saws to carry out mining operations. Although they have achieved good results, they have a large investment in equipment and high mining costs, and they cannot be used on a large scale. How to improve the quality and efficiency of stone mining, minimize environmental damage, reduce the labor intensity of workers, etc., become an urgent need to solve the problem of stone block mining in China.

　　Second, the cutting principle

　　In view of the above situation, the scientific and technical personnel in China have applied the plate cutting mechanism subtly to the mining and achieved good results. The basic principle is: laying the track on the mine surface, and driving the super-large diamond circular saw blade (Ф2000～3500mm) to rotate at a high speed through the host machine to realize the rail cutting. Due to its advantages of less investment, high efficiency, safety, environmental protection, energy saving and low mining costs, it is widely favored by mining companies.

　　Third, technical requirements

　　In addition to the requirement for a good precision of the sawing machine in this mining method, the specification and quality of the ultra-large diamond saw blade are key to this technology. As we all know, the decision to mine the size of blocks is determined by the specifications of the saw blade. At present, the market demand for sheet width is about 1.5m. Therefore, the matching specifications of the diamond circular saw blade must reach Ф3500 or more. At the same time, the field operation environment such as the smoothness of the mine operation, and the cooling swarf cutting relative to the plate, the conditions are even worse. Therefore, more stringent requirements are imposed on the manufacture of saw blade substrates.

　　IV. Comparison of economic and technical indexes with traditional mining methods

　　The application of new mining methods has increased the exploitation rate of resource utilization. Due to the improvement of mining quality, the added value of products has been correspondingly increased. It reduces production costs, while overcoming the disadvantages of traditional mining methods such as poor safety performance and serious environmental damage, and it has great economic benefits and social benefits. V. Use requirements

　　1. Preparation before installation

　　(1) The laying of the track of the sawing machine requires the sleeper to be firm and smooth so as not to shake the cutting process of the saw. The parallelism tolerance of the sawing machine track should be ≤ 5mm, and the horizontality tolerance should be ≤ 2mm.

　　(2) In order to ensure the flatness of the saw blade cutting process, the diameter of the flange of the clamping saw blade is > i280ram, and the unevenness of the flange directly affects the edge jump of the saw blade. Therefore, the user must check the accuracy of the flange before use, generally Ф 280mm flange its unevenness
