6 FAQs about [Pulldown drill rig]

Which rotary drill rig is best for blasthole drilling?

A combination of increased pulldown force, rotary torque, and 2600 cfm airend, the Pit Viper 291 rotary blasthole drill rig is one of the most powerful drills for blasthole drilling. The new Pit Viper 291 rig exceeds all in its class.

How much pushdown does a rotary drill need?

The pushdown required is determined by the hardness of the material being drilled and the drill bit. Mud rotary bits drilling in soft formations are run with lower weight (1,100 to 3,000 lbs per inch of bit diameter) than harder formations which can require up to 5,000 lbs per inch of bit diameter.

What does pushdown mean on a drill bit?

Pushdown: Also called pulldown, crowd force, thrust or weight on the bit (WOB), pushdown refers to the downward pressure applied to the drill string and is measured in weight (pounds/kilograms). The pushdown required is determined by the hardness of the material being drilled and the drill bit.

How much pushdown does a hammer drill need?

When DTH (down the hole) hammer drilling, since the air compressor is providing much of the force for each hammer blow, much less pushdown is required. A general rule of thumb is 500 lbs per inch of bit diameter. RPM: In drilling terms, it is the revolutions per minute of the drill string provided by the drill rig’s rotation head.

What is pullback & pushdown?

Pullback is vital in determining depth capacity as the rig must have sufficient power to be able to retract the drill sting. Pushdown: Also called pulldown, crowd force, thrust or weight on the bit (WOB), pushdown refers to the downward pressure applied to the drill string and is measured in weight (pounds/kilograms).

How much pullback capacity should a drill rig lose?

Therefore, a safety factor of 40 to 50 percent pullback capacity loss should be accounted for. For example, a drill rig such as the K60 having 22,000 lbs of pullback at 50 percent capacity will retract 137 drill rods, 10 ft long, weighing 80 lbs each (in other words, a drill string of 1,370 ft).
