Abstract：To achieve safety,efficient and environment friendly mining,based on the national energy demand and the occurrence of coal and associated resources,the concept of precise coordinated mining and the method of reserving aisles were proposed under the background of the coming scientific and technological innovation.With ecological resources conservation as a premise,precise coordinated mining is a scientific mining method based on the transparent technology of space geophysics,the theory of multi-field coupling as well as the means of digitalization,informatization and intellectualization.It can precisely and quantitatively determine the mining patterns for overlay resources such as coal,oil,unconventional gas,special rare metal and water,and help formulate optimal mining schemes for coal and its associated resources intelligently.This paper took the Ordos basin as a case to analyze the precise coordinated mining of coal and its concomitant special rare metal,and discussed some key scientific issues during the exploitation,which includes the intra-resources interaction,underground water,surface ecology and the digital quantitative,collection and transmission of multi-field dynamic information.The preliminary safety level assessment standards were formulated,the key technologies of precise coordinated mining were further analyzed,and related measures and suggestions were proposed.The outcome of this research would provide favorable reference for medium and long-term exploitation of coal and associated resources.
