摘要
通过对25072工作面贯通测量与施工测量误差之原因分析,找到了在起始边方位角超限,2次测量误差较大时,通过内业计算,解决此类误差的方法。
Through analysis of the reason for construction measure error at measure 25072 working face break through, found the method of solving this kind of error by work computation when starting edge overlimited and two measuring errors were big.
