| Abstract: | The paper proposed a set of drilling tools of large diameter hard rock annular coring with low energy consumption, low cost and high efficiency based on analyzing on the methods of large diameter hard rock coring in domestic and foreign. The prototype of drilling tools has been designed and made. The result of the test of the prototype indicated that this plan and technology of design are feasible and reached the antieipated object of design. A set of drilling tools has been offered for the constructs of large diameter hard rock coring. |
