我队有些矿区平基台是一件很大的工程,有的钻孔要花一两个月才能平好,这样既浪费时间,又增加成本,很不合算。刘庄冶分队在平727孔时付出很大的力量,花了很长时间仅平出三分之一的工程,而15号机施工孔又快完工,马上 Some of the mine’s mining bases are a big project, and some boreholes can take a month or two to be flat. This wastes time and increases costs, which is uneconomical. The Liuzhuang Metallurgical Team paid a great deal of power in the Ping 727 hole. It took only a third of the project to be completed for a long time, and the construction hole of the No. 15 machine was completed quickly.
