摘要 本文提出矿区控制网扩展时,将新网按旧网原有的等级进行布设,并将新、旧网看作一个整体,统一进行平差,并推证了精度估算公式。这种方法在理论上是严密的,计算时规律性很强,便于计算机运算,并使新旧网联接处的精度提高20%左右。 In this paper, it is put forward to extend a densification network by the same precision as the fundamental network's and adjust the densification network and the fundamental network overally considering them as a complete one in mining area. The formulas to approximate the precision of the complete net-work is deduced. The method is strict in theory and can be calculated conveniently by a computer. The precision of the part joining the densificetion network and the fundamental network is about 20%higher than that of the fundamental network
