granite wire saw cutting machine quarrying process

granite wire saw cutting machine cutting stone quarrying process

1. Preparation
(1) mountain stripping: the stripping work is mainly to strip the overburden of the marble ore body, weathering layer, stripping the interlayer, surrounding rock and because of joint crack development and no quarrying value of broken marble, marble ore body exposed, ready for quarrying work. Special attention should be paid to the protection of the ore body, do not allow blasting vibration on the integrity of the stone, lumpiness.
(2) construction work platform: after the marble is exposed, the platform suitable for the granite wire saw cutting machine machine should be excavated, with the general width of 6 meters, the length determined according to the mountain situation, and the stope step height of 5-10 meters. The excavation method generally adopts methods such as drilling and adding expansive agent, blasting method can be adopted for granite, and bedding soil layer can be adopted to build operation platform for gentle working face of mountain.

Preparation before quarrying
(1) drilling
Drilling is a key preparatory work, if the hole drilling is not good, directly affect the string string through, affect the service life of the rope and cutting efficiency, so drilling this process is particularly important. To cut a large block of waste material, three holes must be drilled, that is, a vertical hole and two horizontal holes. The three holes intersect at one point. If the three holes do not intersect at one point, it is troublesome to perforate the diamond string string, or even cannot be pierced. It needs to be drilled again, which reduces the production efficiency. Therefore, drilling must be carried out according to actual conditions and operating procedures. Drilling equipment can be used with multi-function rock drilling, drilling, manual drilling machine.

(2) string
Adopt the method of artificial threading, that is, one end of the rope is fixed on the thin steel wire rope, the other end of the thin steel wire rope is connected with multiple strands of soft wire (usually the wire used for lifting hammer), through the hole, the vertical plane can be used to flush out the soft wire, the horizontal plane with iron wire from the other hole, and then take out the thin steel wire rope lead out granite wire saw cutting machine.
(3) granite wire saw cutting machine is installed in place
After the completion of rope threading, the laying of equipment track shall be carried out first. The track shall be parallel to the horizontal hole, and the level of the track plane shall be measured with a level ruler to meet the requirements. Finally, the granite wire saw cutting machine shall be hoisted onto the track, and the granite wire saw cutting machine shall be hung up and connected to the power supply. Because of the heavy equipment, plus cutting a plane, need to move the equipment, can be used mast crane, forklift, loader, excavator, any one of the equipment to move the saw machine;
(4) connect the water source and install the cooling water pipe. Generally, two water pipes are required, one is set at the inlet hole position of the rope and the other is set at the outlet position of the rope, and the inlet position and outlet direction shall be adjusted continuously as the cutting progress requires.
