近五年来,苏联某矿积蓄了丰富的快速送道经验,从1943年到1951年的八年过程中,曾经进行了115个快速送道的先进记录和11000米的快速坑道掘进。其中最快的速度是月进162.4米(使用电耙子捣矿)和月进268.6米(用风簸箕捣矿),而完成此进度的敏查里波夫掘进小组曾因此获得斯大林奖金,并坚持了数年来全联金属矿山快速送道的先进 In the past five years, a Soviet mine has accumulated a wealth of fast track experience. During the eight years from 1943 to 1951, there were 115 advanced records of fast track and 11,000 meters of rapid tunneling. One of the fastest speeds was 162.4 meters per month (rake pounding with electric rake) and 268.6 meters per month (plowing with dustpan), and the Minreapov excavation team who completed the project won the Stalin prize and insisted Over the years the rapid progress of all metal mines advanced
