Numerical Analysis of Super Drill of Shaft Well Boring Machine in the Stress Field

Abstract:

We research the super two-stage rapid drill of shaft well boring machine, taking the mathematical model of the drill in the stress field of shaft bottom as theoretical basis. Taking linear elastic and nonlinear features of element material into consideration, we establish element model in the stress field of shaft bottom and material model of stratum rock. Furthermore, we use the finite element method to numerically simulate the fragment intake effect of the super drills with diameter of 400mm and 800mm respectively. The result can be applied in the field of mine exploiting and tunnel advancement.
