Abstract: In view of the features of large reserves,low grade, deep chute, high level of fine ore, and large capacity in Zijinshan Gold Mine, and together with the impact of 1600 mm annual rainfall, the design, construction, congestion handling technology for eight deep chutes are introduced in Zijinshan open pit gold mine. Based on this, the technical measures for safe and high efficient operation of the chute are proposed, and the economic analysis and evaluation on the adit chute technique are made. The application of the adit chute in safety and high efficiency in Zijinshan gold mine greatly reduce the transportation costs, with good economic and social benefits achieved.

Key words: Adit deep chute, Open gold mine, Application
