This paper proposes to build a six⁃dimension smart mining control system of “perception，transmission，deci⁃ sion⁃making，implementation，operation and maintenance，and supervision” based on the supporting environment of the mine internet of things and advanced sensing communication methods. Furthermore，under the guidance of this system，the technical route and system scheme of unmanned smart mining control are developed. Finally，the latest development of the theory and technology of unmanned smart mining system in coal mines is discussed in detail. Dual spectrum thermal infrared camera and image enhancement technology are proposed to solve the problem of dust pene⁃ tration of visual monitoring under the production conditions of fully mechanized mining face. The technology of multi⁃ ple⁃camera video frame image fusion and panorama video splicing is proposed to solve the problems of large angle cov⁃ erage and real⁃time dead angle video monitoring in the working face. The 3D color search method is used to solve the problem that the enhancement algorithm is difficult to meet the underground visual measurement task in quality and re⁃ al⁃time. The adaptive control of the working face equipment is further developed，including that the accurate 3D geo⁃ logical model is built，and the mining prediction and dynamic correction of the model is proposed，which provide accu⁃ rate geological support for smart mining. Combined with the correction technology of shearer cutting template and the smart control technology of multi⁃source information fusion of working face，the cutting route of shearer can be predic⁃ ted. The new generation of information technology is used to achieve high⁃quality video transmission and meet the wireless access of smart control and sensing devices. A long⁃distance hydraulic guarantee technology is implemented to alleviate maintenance intensity and improve safety in limited mining space. The Yujialiang Coal Mine has proposed a new generation of smart unmanned coal mining control technology method，and designed a smart unmanned min⁃ ing mode of “intelligent decision⁃making in surface office，automatic execution in underground mine，and unmanned operation in mine working face”. No. 627 smart working face of the Huangling No. 1 Coal Mine has focused on the re⁃ search and development of key technologies such as the network control system of “one network to the bottom”，the autonomous planning coal cutting technology of shearers based on transparent geology，the automatic tracking vide⁃ o technology of PTZ cameras，and the ground remote control platform based on integrated operation seats. Normalized production has been realized with one person patrolling the working face，the shearer independently planning and cut⁃ ting，and two people on the surface for remote auxiliary control.
