浅井工程是地质普查勘探工作的重要手段之一。我队自成立以来，每年施工浅井的工作量均在一千米以上，绝大部份浅井深度为15至20米，不少工程尚需向两侧掘进10至20米的岔巷。一九六一年以前浅井工程完全采用木质辘轳作提升工具，效率低，又笨重，不安全。在老工人、队领导、技术人员共同研究和努力下，用127毫米的套管做滚筒，以50毫米的钻杆做支架，自行制造了一批带有刹车装置的绞车，对提高浅井工程的掘进效率，保证安全生产起了重要作用。 Asai engineering is one of the important means of geology survey and exploration. Since the establishment of our team, the annual workload of construction shallow wells is over one thousand meters. Most of the shallow wells have a depth of 15 to 20 meters. Many projects still need to drive 10 to 20 meters of turnouts to both sides. As early as 1961, the shallow shaft works were entirely made of wooden wheel pullers for raising tools, which were inefficient, unwieldy and unsafe. Under the common research and efforts of veteran workers, team leaders and technicians, a 127 mm casing is used as a drum, a 50 mm drill pipe is used as a bracket, a batch of winches with brake devices are manufactured by themselves, Driving efficiency, to ensure safety in production has played an important role.
