一冶第三井巷工程公司,在支援铁路建设中,继1965年四月份创造隧道单口月成洞107米之后,又连续四个月保持月进百米以上的纪录。在隧道导坑掘进中,成绩更为优异,同年6～10月间,掘进月进尺节节上升,并在十月份创造月进338.2米的新纪录,五个月的平均月进尺达229.51米。为冶金系统大断面隧道施工树立了榜样。表1所示为该公司三队6～10月份掘进导坑的进尺纪录。

A Third Metallurgical Lane Engineering Company, in support of the railway construction, following the April 1965 creation of a tunnel of a month after the hole into a hole 107 meters, but also for four consecutive months to maintain a record of more than 100 meters. During the tunneling work, the result was even better. During the period of June to October of the same year, the progress of driving the tunnel saw a rise. In October, it created a new record of 338.2 meters per month. The monthly average of the five months reached 229.51 meters. The metallurgical system for the construction of large cross-section tunnel set an example. Table 1 shows the company three teams from June to October excavation pit footage record.
