阐述了补连塔煤矿改扩建后在地面导线控制网被破坏的情况下，通过收集地面已有的数据恢复和建立地面GPS控制网，利用地面控制成果对井下导线控制网进行布设和观测，与已有的井下导线系统联测并进行平差计算，从而达到对井下已形成的巷道进行系统的改算和优化。%The ground conductor control network was destroyed when mine reconstructing in Bulianta coal mine. By collecting the ground existing data, constructing ground GPS control network, the underground conductor control network was layout and contacted to the underground conductor system based the ground control results. Finally systematic transformation optimization was completed for the existed underground tunnels by Adjustment calculation.
