| Abstract: | This paper presented three methods for anchor hole expansion, and discussed the advantages and disadvantages of each method. Of the three methods, the water jet technology and pointed out its possibility and good effect through experiments is emphasized. This paper also put forward a new scheme which ameliorated the drilling machine so that it could expand the hole been drilled by water jet. Therefore it improved work efficiency greatly. |
