Abstract: In order to ensure the through survey project completed with high accuracy in the main and auxiliary inclined shafts of Tongfa Dongzhouyao Mine, with th e analysis on the through survey project information and technical methods of the main and auxiliary inclined shafts, the high accurate GPS control net was applied to t he plane control survey on the surface ground and the rigonometrical elevation survey with the total station was applied to the elevation control.The underground mine control survey with a first grade traverse layout was applied to calculate the two corrections for the inclined length reduced to the projection level plane and the projecti on level plane reduced to the Gauss projection plane.With the above measures, a high accuracy special control net was established and the through survey project in th e large mine was successfully completed.
