Abstract: | The nontraditional mining industry is an important part of nontraditional mineral resources projects. It is a new mining industry focusing on the application of new science and technology, producing high value added outputs, offering comprehensive services, protecting the environment and saving energy sources. This paper discusses main principles of two kinds of nontraditional miming technology: the drilling hydraulic fracturing and drilling hydraulic mining applied to the coalbed methane production. Furthermore, this paper introduces the characteristics and application of these two kinds of technology. |
