| Abstract:A new technological method, diamond drilling cutter, is adapted while designing diamond coring bits with diameter of 615 mm. The pattern of the cutters and the technique inserted them into and welded them with bit body are introduced. The good results of application of the technology were got in geological survey for determining the damsite of Guxian Hydro-junction over the Yellow River. |
