With the continuous development of the economy, the market demand for granite stone has gradually increased in recent years. The mining method of granite stone has also changed from traditional blasting mining to mechanized mining. This article introduces several methods of granite stone mining. blasting mining Explosive mining has always been the mainstream method of stone mining in the past, and there are still some mines still using this method until now. The blasting method is more damaging to the natural environment, and the yield of blocks is low, and it also has a certain degree of safety. Hidden danger. Flame cutting Flame cutting is a high-speed flame ejected from the nozzle of a flame cutting machine, which heats and impacts the rock. Due to the different thermal reaction characteristics of different minerals in the rock, it will burst and peel off, and gradually form separation grooves. This method is suitable for high-quartz content and small heat capacity. , Rocks with poor thermal conductivity, such as granite stone mining. Diamond wire saw mining The use of diamond wire saw cutting machine for granite stone mining is also a widely used mining method at present. The working principle of the wire saw machine is to drive the beaded rope through the main flywheel to perform closed-loop high-speed rotation to cut the stone. Wire saw machine + circular saw combined mining The combined mining method of diamond wire saw machine + mining disc saw is to use the disc saw machine to cut the vertical surface of the ore body, and use the diamond wire saw machine to cut the horizontal bottom surface of the stone. This method is suitable for the integrity of the ore body. Small and medium scale mechanized granite stone mining. Stone Cutting Machine: https://www.wanlongstone.com/
