Experimental study of rock fracture process during rotary-impact drilling
Authors:
Abstract
The intensity of rock destruction in rotary-impact drilling depends, as is known, on a number of factors, the most important of which are the energy and frequency of impacts, the magnitude of axial load and the speed of rotation of the tool. The joint action of these factors causes a very complex nature of the drilling process, which makes the study of its regularities very difficult. Insufficient study of the mechanism of rock destruction and the process of interaction of the tool with the rock during rotary impact drilling restrains the development of this effective method of drilling.
