摘 要:为确保同发东周窑矿主副斜井贯通测量工程高精度完成,通过对该矿主副斜井贯通测量工程资料和技术方法分析,地面控制测量平面控制采用高精度GPS控制网,高程控制采用全站仪三角高程测量。井下控制测量采用一级导线布设,计算斜长化归到投影水准面及投影水准面化归到高斯投影面2项改正。通过以上措施建立了高精度专用控制网,完成了该矿特大型贯通测量工程。In order to ensure the through survey project completed with high accuracy in the main and auxiliary inclined shafts of Tongfa Dongzhouyao Mine,with the 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 the 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 projection 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 the large mine was successfully completed.
