Mining method for granite mines-diamond string bead wire saw cutting method

The so-called diamond string bead wire saw cutting method utilizes the principle that the hardness of diamond is higher than that of granite. It uses driving motor to drive closed-loop circulation movement of diamond string bead wire saw and enables diamond particles to cut granite directly, thus achieving the effect of separating large pieces of stone wastes from the mine.

However, it should be noticed that the stone scrap produced by diamond string bead wire saw-cutting method can not meet the requirements of standard scrap specifications in practice.

 

Therefore, after separating the scrap, operators are required to further saw, trim and reshape the scrap to meet the actual needs of transportation and production. In addition, during the use of diamond string bead wire saw cutting method, the operator needs to continuously inject proper amount of cooling water into the saw slot to prevent excessive wear of diamond particles due to excessive temperature, while flowing water can take away the powder produced during the sawing process.

 

At present, diamond string bead rope saw cutting method is widely used in the mining of granite mines by domestic large and medium-sized mining enterprises.

 

For one thing, this method has good adaptability to the sawing of different kinds of rocks and can cut granite with high efficiency.

 

Secondly, it is because this method can prevent mining activities from destroying the mine body, reduce the waste rate of stone resources and improve the yield of waste material.

 

Thirdly, this method is very suitable for all kinds of mines with different qualities, and can be sawed vertically or horizontally without space restriction.

 

Fourthly, the scrap cut by this method is usually of large size. However, this method is not without drawbacks. At present, the mining cost of diamond string bead rope saw cutting method is relatively high, the fragile parts are relatively expensive, and the professional technology of operators is also put forward higher requirements. Therefore, the use of this method in domestic granite mines is just the beginning.
