| Abstract: | Based on the characteristics of the diamond drilling process
and in the light of simulation test, a method of determining the abrasiveness of rocks is proposed. By using the special device and material, the author has studied following points: the mechanism of the wear of synthetic diamond and the bit matrix, the law of kinetic friction factor and its variational range between diamond and rocks, the influence of the parameter of fragmental rock on abrasiveness as well as the measurement of abrasiveness of 19 kinds of rocks on uniform rules of operation. In addition to analysing the relation between abrasiveness and physical and mechanical properties of rocks,and that between abrasiveness and technical parameters of rock failure, the writer suggests a grading scheme of rocks according to their abrasiveness. Finally, this article reports the preliminary research of the adaptability between wear-resistance of bit matrix and abrasiveness of rocks, and puts forward a discriminant for evaluating the effect of adaptability. |
