| Abstract:Analysis and discussion are conducted on the bit pressure determination method for impregnated diamond bits in terms of diamond exposure, distibution, compressive strength and indentation hardness of rock, and rock fragmentation Tnechanism. A comprehensive rock fragmentation mechamism is presented. The method and formula for calculating bit weight are determined. |
