- •
It is helpful to the understanding of auger drilling mechanism.
- •
It is helpful to the accurate calculation of cuttings transportation power.
- •
Cuttings transportation model is determined by rotation speed and feed rate.
- •
The gravitational environments affect the critical rotation speed remarkably.
