6 FAQs about [Kq-150 down-the-hole drill operating procedures]

How much hold back should be increased in DTH drilling?

Hold back should be increased more and more as additional rods are added and as drilling progresses. DTH drilling is primarily percussive drilling using the energy imparted by the hammer piston to the rock through the bit. Any attempts to apply too much weight could damage the bit, hammer and drill string and impair the drilling rate.

How do you use a DTH drill?

Thrust should be kept as low as possible at all times to avoid excessive vibration in the drill string. Hold back should be increased more and more as additional rods are added and as drilling progresses. DTH drilling is primarily percussive drilling using the energy imparted by the hammer piston to the rock through the bit.

Can a drill stand be used for overhead drilling?

Top : An additional means of securing the drill stand must be employed when the machine is used for horizontal drilling with the vacuum securing method. Bottom : Use of the vacuum securing method for overhead drilling with the drill stand is not permissible.

How does DTH drilling work?

With DTH drilling, contractors can change the drill that they were using for the current directional bore to a rock drill when they encounter rock by connecting the drill with a compressor and a steerable hammer. Well drilling also needed changes to be made to rotary drilling when the well needed to take a turn.

How long did it take to drill a 12,000 ft hole?

The original estimate for completion of a 12,000-foot hole was 30 days using the conventional rotary technique, which was reduced to 13 days using the DTH method. Before DTH was used, drillers would typically case the vertical portion of the well and convert to rotary drilling to drill at a tangent.

What precautions should a drilling operator take?

When performing drilling that requires the use of water, route the water away from the operator’s work area or use a liquid collection device. Such precautionary measures keep the operator’s work area dry and reduce the risk of electrical shock.
