Abstract: The shaft construction method of coal mine in China is dominated by conventional sinking method and supplemented by special sinking method. This paper introduces the development course and application status of drilling technology using mechanical rock breaking with shaft drilling machine and raise boring machine. Safety and efficiency in shaft excavation are the cornerstone of deep shaft construction. The development of mechanized sinking technology and equipment is a guarantee of less humanized and unmanned construction of deep shaft. The research status of drilling technology and equipment of partial section shaft boring machine is analyzed. The need to develop full section shaft boring machine is proposed. The characteristics and applicability of key technology, including sidewall stabilization, sinking process, drilling parameter, are discussed. In view of the parallel operation of excavation, slag discharge and support during construction, rock breaking, host system, and directed driling will become the direction of technical research and the difficult point of engineering application. Drilling technique of full section shaft boring machine is the development direction and trend of integrated mechanized shaft sinking, which is of great significance to mine construction technology development and underground engineering construction.
