| Abstract: | It is a major trend of geological survey to expand deep- er, but deep drilling is complex and difficult, while the drilling of unstable complex layer is a difficulty. The skill of bare wall drilling for uncovered pipe on 1000m thick covering layer is a great exploration, which will create a safer and more economical method if successful. |
