Abstract: Sanshandao Gold Mine is one of main mines in Shan Dong Gold Group，which has entered deep mining stage and the mining depth will exceed one kilometer.With mining depth raising，problems caused by large quantity of hot water inflow and ground temperature increasing seriously affect safe production；Trackless mining equipments are widely used which exhaust lots emissions.Based on collection of relevant data，evaluation of current ventilation system，treatment scheme supported by network solution was proposed.The production environment underground and mining efficiency were effectively improved after the scheme implementation.

Key words: Metal mine, Air-cooling in deep high temperature well, Aeration cooling, Network solution
