Abstract

In order to explore the crushing effect of roof teeth on granite in Qinghai Oilfield, the rock breaking efficiency of roof teeth was studied. Through the indoor single tooth rock breaking experiment, rock mechanics parameter experiment and numerical simulation of the rock breaking process of roof teeth, the influence of cutting parameters (depth and rake angle) of roof teeth and tooth arrangement mode on the rock breaking efficiency of roof teeth is judged. Through analysis, the best cutting parameters of plane teeth are 5 °, 3mm; The best cutting parameter of ridge teeth is 5 °, 2mm deep, and the rock breaking effect of ridge teeth is better than that of plane teeth.
