In stone mining, there are two common mining methods, one is open-pit mining, the other is cave mining. The two methods have their own advantages and disadvantages. This paper introduces the advantages of cave mining method in stone mining
More environmentally friendly
Cave mining can reduce or basically not damage the vegetation and natural environment on the surface of the ore body, which is more environmentally friendly than open-pit mining;
Low comprehensive cost
The comprehensive mining cost of tunnel mining is lower than that of open-pit mining because there is no need for large-scale earthwork stripping and the cost of residue transportation and cleaning is reduced;
Not affected by the weather
In alpine regions, the exploitation of stone is obviously limited by climatic conditions. The cycle of stone mining in a year is limited, while the way of cave mining is not easy to be affected by the weather. In time, it can be mined as usual in snowy days in winter and rainy days in summer.
Reduce resource waste
The method of tunnel mining can selectively mine the optimal stone color part of the ore body, while leaving the unwanted part of the ore body as a safe pillar, which can obtain a higher waste rate and reduce the waste of stone resources;
The above is about the advantages of cave mining. For more information about the stone industry, please visit the official website of Huada.
