Under the background of"double carbon",Inner Mongolia,as an important national energy and strategic resource base,is committed to ecological priority and green development,and is implementing the integration and demonstration of ecological restoration technology in open-pit coal mines to promote the construction of green mines.In view of the current situation of ecological restoration in open-pit coal mines in Inner Mongolia,based on the basic data of ecological restoration patents in Inner Mongolia open-pit coal mines from 2005 to 2022,the patent analysis method was used to conduct an in-depth discussion on the patent structure of ecological restoration technology in Inner Mongolia open-pit coal mines from the aspects of technical field distribution,regional distribution and patent technology composition effect.It is concluded that the general trend of ecological restoration patent technology in Inner Mongolia open-pit coal mine is good,but the overall innovation ability and innovation level still have room for further development,the regional difference of technological innovation is obvious,the insufficient possession of valid patents,the effectiveness of patented technology needs to be improved.Based on the above conclusions,this study puts forward some suggestions to optimize the patent layout strategy,increase the conversion rate of scientific and technological achievements,and strengthen the integration and demonstration of patent technology,so as to further play the role of Inner Mongolia as an important ecological security barrier in northern China.
