| Abstract: | To study on the wear mechanism of drilling bits in drilling complex strata of south coalfields,wehave developed a kind of wireline core drilling bit adaptable to the complex strata.At the same time,we have tak-en an efficient test on keeping the inside and outside diameter size of electroplated diamond bits.This kind ofdrilling bit has obtained evident drilling effect in different types of strata in the complex coalfield. |
