Abstract：While coal is dominating the energy resource of China,the proportion of coal in the primary energy consumption,with the increasing shut-down of coal mines,is decreasing in recent years due to importance of clean,green and low carbon energy.New conception and strategy on the shut-down mines need to be built beyond the old and stereotypical thoughts along with the development of society,science and technology.We believe that the shut-down mines can not only restrain further ecological damage,but also provide precious underground space resource.The resource utilization and transition and upgrade of shut-down coal mines is not only an economic,but also a scientific concern.How we solve this problem will have a significant impact on the mining ecology,urban and rural construction and energy strategy of China in the future.In this paper,we propose six principles on the scientific transformation and upgrading of the shut-down mines,and give emphasis on the stereoscopic and ecological development conception,the strategic ideation on underground space utilization,as well as the historical culture view on shut-down mines.The key technologies involved in the utilization of the shut-down mines are discussed in details,including the development of underground ecological city,underground pumping-storage power generation,parking lots,medicine and nursing,agricultural cultivation,ecological landscape and scientific exploration.Industrial heritage declaration of some typical and his-torical mines will also be involved.The above strategic concepts and corresponding key technologies are expected to provide new solutions for the resources utilization and stereoscopic exploitation on the shut-down coal mines and associated transformation and upgrading in China.
