On April 1st, the diamond wire saw machine was tested at the “Xianshanhong†granite mine of Huishan County Huiyu Stone Industry Co., Ltd. and achieved initial success. Stone mines are in a variety of ways, and the characteristics of stone are “variously differentâ€. However, it is an important principle that stone mining should be established in order to find a mining model that can be adapted to the characteristics of local mines. The inevitable requirement for sustained and healthy development. Shanshan Stone Park has been committed to promoting the popularization of advanced stone mining technology. Due to the hard stone quality, the Shanshan Red Mine has adopted traditional flame cutting and rock drilling and bursting combined mining methods in the past mining methods. This relatively backward mining method has great damage to the internal structure of the stone; More labor, employees are labor-intensive, in a state of heavy physical strength, relying on human tactics to achieve scale production capacity; extremely dependent on fire blasting, safety and security, safe production management is difficult; low yield, irregular shape, serious waste of resources High energy consumption and low efficiency. In order to change this situation, since 2008, the Shanshan Stone Park has actively guided and encouraged mining companies to use circular saw mining technology to improve the rate of landfall from the original 30% for the stone quality of the “Little Purple Star Cloud†stone mine. It is 60% of the present. In 2009, the company began trials of the circular saw mining technology for the “Qianshanhong†variety. Through continuous trials, the “Chongshanhong†variety used circular saw mining technology in 2010 has also achieved success. The block rate has also increased from the previous 30% to the present. About 40%, some pits reach 60%. The successful trial of the diamond wire saw machine indicates the arrival of a new era of stone mining technology in Shanshan County. First, the production efficiency has been greatly improved, the blocks have good regularity, the flatness of the material surface is high, the transportation cost of the block material is low, the material processing cost is saved, the comprehensive mining cost is more competitive, and the economic benefits of the enterprise are significantly improved. The non-renewable natural resources can be scientifically and rationally developed and utilized, the yield rate is greatly improved, the amount of waste is greatly reduced, and the mine ecological environment is effectively improved. Third, the stone mines must be relied on traditional mining workers for a long time, and the mining workers have more space to choose. Large, the restrictions on employment restrictions on the sustainable development of the mine will be completely broken; Fourth, the labor intensity of workers is effectively alleviated, and safe production is more secure, which will greatly reduce the risk probability of stone mines, a high-risk special industry.
