Abstract: The deep part development and transportation system  in Xishan mining area of Sanshandao Gold Mine are renovated to be cost-effective,changing the previous transportation system with trackless transport to the surface(or -243 m level) and designing as well as constructing the transfer system at -537 m  level.Based on that,the ores and waste rocks from production and infrastructure are all transferred to the -600 m level at Xinli mining area and transported on track with 11 6 m3 carts pulled by 14 t electric locomotive,and lifted to the surface through the Xinli main combination shaft.The average transportation distance is shortened by 2 950 m,transportation cost saved excavation is 9.18 yuan/m3,transportation cost saved annually is 3.170 8 million yuan for the optimized transportation system.The optimization creates significant economic profits and can be referred to by similar mines.
