同志们!这次红城(海丰)坑探现场会议共开了五天,有南方九省的代表114人参加,大会上发言的有31人。经过小组讨论、现场参观以及竞赛倡议,使我们开阔了眼界,学到了不少东西;同时也提高了思想,明确了方向。总的来说,会议开的很好;但会议时间比较短,有些经验未得充分深入的讨论。现在我仅就会议情况,着重谈谈手掘坑探工程方面的几个问题。 Comrades! The meeting of the Red City (Haifeng) pit site was held for a total of five days, with 114 delegates from nine southern provinces participating in the conference. There were 31 speakers at the conference. After group discussions, on-site visits and competition initiatives, we have broadened our horizons and learned a lot; at the same time, we have also improved our thinking and clarified the direction. In general, the meeting opened well; however, the meeting time was short and some of the experiences were not thoroughly discussed in depth. Now I will only talk about the conference situation, focusing on several issues related to excavation and excavation engineering.
