三山岛金矿连续规模化智能开采工艺研究及应用

过去的数十年，地下金属矿山采矿方法在崩落、空场和充填三大类的基础上,通过不断地改进和完善，形成了各种各样的采矿工艺，为我国地下金属矿山安全高效回采提供了设计依据。但当前开采工艺仍存在着开拓、采切工艺复杂，安全性差，生产能力小等突出问题，制约了资源安全高效开发。结合矿山生产实践，阐述了地下金属矿山生产模式及开采工艺演化过程，以三山岛金矿无人采矿示范区为工程背景，研发了连续规模化智能开采工艺，即采用连续分段空场嗣后充填采矿法对矿石进行回采，从开采工序连续性、地压调控及时性、采矿设备适配性三方面设计了开拓方案、采矿工艺及铲装运输环节，可为具有类似条件的矿山生产设计提供参考。

Study and Application of Continuous Large-scale Intelligent Mining Technology in Sanshandao Gold Mine

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.
