To clarify the status of deep exploration technology, find solutions to related problems, and explore the future direction of development, this paper reviews at first the deep coal and coalbed methane exploration status at home and abroad and points out that deep mining has become an inevitable trend. Secondly, from the perspective of deep coal-bed methane, the paper argues that the deep special geological conditions will affect the accumulation mechanism and occurrence state of deep coalbed methane, it is thus necessary to establish an exploration idea suitable for deep coal-bed methane and improve the theoretical basis of deep coalbed methane geology. Then frontier technologies and re-lated technical problems such as deep multi-gas comining, carbon dioxide gas displacement of coalbed methane and synchronous storage, deep coalbed methane intelligent drainage are elaborated. Finally, from the perspective of deep coal exploration and development, the current advanced technologies such as deep coal fluidized mining, coal under-ground gasification coupled carbon dioxide capture and storage, deep coal and geothermal resources collaborative mining are discussed. As deep mining is developing towards automation and AI,, continuous progress of basic geo-logical theory and exploration and development technology will make deep coal and coalbed methane become the main battlefield of future exploration and development.
