6 FAQs about [Voster rock drill parameters]
How to optimize drilling parameters?
Optimizing drilling parameters requires careful adjustments among rotary speed, thrust on the bit, percussion blow count and energy, and sufficient volume of compressed air at an adequate pressure to remove drilled rock cuttings. drilling cost per foot and wear on the bit and drill string are minimized.
What are drilling parameters?
Drilling parameters play a large role in helping drillers achieve superior drilling performance and long equipment life. They are basic recommendations that help guide a driller avoid burning core bits or damaging other drilling equipment, and help achieve a good rate of penetration and core recovery.
Can a portable drilling machine drill rocks with different strength range?
The portable drilling machine is able to drill the rocks with different strength range coincident with measure and record the parameters. A set of drilling experiments were conducted on three different rocks ranged from weak, medium and hard strength.
What factors affect drilling parameters?
There is a clear relationship between the drilling parameters and all others factors in drilling, such as the diameter of the equipment you’re using, rock hardness or ground variability. We have seen that when drilling conditions change, drillers will adjust their drilling parameters.
Which servomotor is used for drilling a rock?
Two different servomotors are used (Fig. 7). One of them provides thrust force up to 1200 N, which is transferred to a rock by a ballscroll via a timing belt. The other servomotor called drilling servomotor, which is connected to the gearbox with a maximum capacity of 6 N m and provides the necessary torque for drilling.
What are the characteristics of a rock based drilling experiment?
A set of drilling experiments were conducted on three different rocks ranged from weak, medium and hard strength. Obtained results based on proposed model for uniaxial compressive strength, cohesion and internal friction angle of rock are well fitted to the results of the conventional standard tests. 1.
