Research and Application of Minimally-Staffed Top Coal Caving Technology in Baode Coal Mine

Abstract：To solve the problems of low automation rate of equipment and high labor intensity in fully mechanized caving face, Beijing Tianma ZhiKong Science and Technology Co., Ltd. conducted research on the minimally-staffed top coal caving technology based on the fully mechanized caving face of Baode Coal Mine. The study focused on three systems: intelligent perception, intelligent control, and intelligent management. It achieved intelligent perception functions such as 3D scanning for face inspection, AI video monitoring, and equipment condition monitoring. It overcame three core control technologies: autonomous shearing technology, three-level integrated intelligent coal caving technology, and coal flow load balance. A transparent mining intelligent fully mechanized caving management platform was established, forming a smart fully mechanized caving mining mode characterized by 'intelligent mining and caving, coordinated centralized control, and remote intervention'. The research and application results show that the minimally-staffed top coal caving technology has improved the level of intelligence and mining efficiency of the fully mechanized caving face in Baode Coal Mine, formed demonstration application results, and provided references for the research on intelligent mining of similar faces.
