摘　　要：主要介绍山西A煤矿+770 m矿井贯通工程,对贯通工程中的所得数据进行分析,分析造成贯通精度的误差和减低误差的措施,对比分析了煤矿矿井映射校正误差和贯通精度的联系,井下巷道贯通总误差受井下导线测量、立井定向、地表变化等误差干扰,探讨分析能有效控制精度的手段。This paper mainly introduced ＋770 m holing through project of A coal mine in Shanxi, analyzed the data obtained in holing through project, the errors in it and the measures that reduced errors, and compared and analyzed the connection between error correction by mapping and holing through precision in the coal mine. The total error of holing through in underground tunnel was disturbed by the errors in underground wire measurement, shaft orientation and surface change, etc.. This paper explored and analyzed methods to effectively control the precision.
