Short summary
This paper studies the rock breaking efficiency and wear resistance under different rock samples by researching the particle size and concentration of diamond cutting elements, and obtains the influence law of particle size and concentration on rock breaking efficiency and wear resistance under different rock samples. The research results have guiding significance for the design of impregnated diamond in high abrasive and difficult formations.
