Abstract: In the past few decades,based on the three categories of caving,open stope and filling,various deformation mining technologies have been formed through continuous improvement and perfection,which provides design basis for underground metal mining in China.At present,there are still some prominent problems in mining technology,such as development,complex mining and cutting technology,poor safety and small production capacity,which restrict the safe and efficient development of resources.Combined with the mine production practice,the production mode and mining technology evolution process of underground metal mines are analyzed.Taking the unmanned mining demonstration area of Sanshandao Gold Mine as the engineering background,the continuous scale intelligent mining technology are developed,that is,the continuous sublevel open stoping with subsequent filling mining method is adopted for ore mining.The development plan,mining technology and shovel loading and transportation links are designed from three aspects of the continuity of mining process,the timeliness of ground pressure control and the adaptability of mining equipment,so as to provide reference for the production design of mines with similar conditions.
