摘要
新屯矿-190与-300跨水平联络巷贯通工程为一井内的重要贯通工程,为保证贯通精度,采取了高精度红外光电测距仪进行了边长测量,主要大巷全部进行了7"控制,确保联络巷的准确无误贯通。
Across horizontal connection through engineering between Xintun -190 and -300 was an important project of a well. In order to ensure breakthrough precision,high precision infrared photoelectric rangefinder for length measuring was adopted, 7 ＂control was widely used in main roadways to guarantee accuracy of contact through lane.
