Abstract
According to the practical problems encountered in coalmine drilling, a detailed analysis of the loads in the drilling process and fatigue mechanism has been done. Based on the above, the paper have studied the cracks propagation speed of the dill pipes used in coalmine, and proposed the measures for improving the fatigue life.
