Development and prospect of large mining height longwall mining technology and equipment in China
In order to promote the development of large mining height longwall mining technology and equipment,and achieve high-yield and efficient coal mining.In this paper,the development history of large mining height fully mechanized mining in China is elaborated;the entire process and successful experience of the exploration,introduction,localization substitution,and innovation-led development of large mining height fully mechanized mining since the early stage of reform and opening up.It is believed that the technology is an important support for ensuring energy supply in China,which contributes to the innovation of mining technology through continuous theoretical research,driving the technological upgrading of the entire coal industry chain and promoting the leapfrog development of China's coal mining equipment manufacturing industry.For a considerable period of time in the future,technological innovation will still be the foundation for the development of the coal industry.Only through process innovation can the development of large mining height fully mechanized mining technology be promoted towards high-end,intelligent,and green directions.It is the inevitable path for China's coal industry development to lead the development of new quality productivity with the new energy security strategy.
