(1) Mountain stripping: The stripping work is mainly to strip off the covering soil and weathered layer on the marble ore body, strip off the interlayer, surrounding rock and the broken marble that has no mining value due to the development of joints and cracks, so that the marble ore body is exposed. Prepare for mining work. Special attention should be paid to the protection of the ore body, and blasting vibrations are not allowed to affect the integrity and lumpiness of the stone.
(2) Construction of the working platform: After the marble is exposed, a platform suitable for diamond wire sawing machines should be excavated. The width is generally 6 meters, and the length is determined according to the mountain terrain. The height of the steps in the mining field is 5-10 meters. The excavation method generally adopts methods such as drilling and expansion agent. The blasting method can be used for granite, and the working platform can be constructed by laying a layer of soil on the working surface with a relatively flat mountain.
