Research on Cone Angle of Cutter Head for Big Diameter Shaft with Analysis of Drilling Mechanics

Article Preview

Abstract:

In order to get a high drilling speed of shaft of nearly 13 m diameter, the authers studied on the shape of the cutter head, particularly about the cone angle. The paper discussed the motion process of slurry of drilling shaft, analysed the forces on the cutter head, and the forces on the cuttings and the motions of the cuttings in slurry. The results show that, the cone angle of the cutter head can be minished at least 20 degree.
