China's abundant stone resources, contains a large number of granite, slate, sandstone and marble. However, the stone is a non-renewable resource, effective use of limited resources, is before us a serious problem. First and foremost is the issue of mining: Tower blocks of thousands of mines in different provinces, different locations. Mining methods vary with the maturity of the technology, the exploitation of advanced technology and better position the mine, waste less, finished product rate, while the mining technology behind the original Blasting or use of mines, mining rate of finished material from the end of the mine waste Serious. It is understood that the acquisition of mines in the stone business, have found traces of the past predatory exploitation of mining resources, severely damaged, not only affects the volume ratio and also reduce the local tax revenue. Since then, the phenomenon of perspective, the specification mine exploitation, the introduction of advanced mining technology, the small mining units into a unified, standardized management, integration and mining resources exploitation of resources in order to reduce mining waste of resources is necessary. Chengde County, Hebei, Sichuan Miyi, Rongcheng City, Shandong Province by the market leadership bid, standardized method of mining is worth promoting, in a sense, but also effectively prevent the loss of state assets hidden.
