Rotary Drilling Method

The drilling principle is to use a high pull down force (weight-on-bit), rotate the drill bit, and blow the rock cuttings to the surface with compressed air. Hardrock drills typically use the Rotary method to drill blast holes from 200 mm (7 7/8") to 311 mm (12 ") diameter.Get price

The Expanding World of Reverse Circulation Drilling –

Traut notes the air volume required for a DTFR borehole is relatively low versus air rotary. He says approximate air is 500 to 600 cfm at 150 to 350 psi with the psi more a function of hole depth. Although not used as frequently as a tricone bit when harder rock is encountered, Traut uses a downhole hammer with a diverter/packer positioned above the interchange (crossover).Get price

RC Drilling Comparisons

Reverse Circulation (or RC) drilling is one of the most frequently used methods of drilling used across the world as it is more cost effective and efficient then other methods of drilling. When compared to RAB (Rotary Air Blast) and diamond drilling, RC drilling seems to be somewhere in the middle when it comes to cost, time, quality of samples, technique and depth.Get price

Drilling Techniques for Mining Exploration

13/12/2018Rotary air blasting is a type of rotary drilling, where a blade bit or roller-cone bit is used to cut and break rock with a simple blade mounted on the end of a rotating drill stem. This stem is rotated while a thrust is applied to it by a pulldown mechanism that uses up to 65 percent of the weight of the machine.Get price

Rotary percussive drilling (down

Compressed air is usually used for this purpose. Special procedures, though, can also involve flushing with water. The flushing medium is pressed through the drill pipes, down-the-hole hammer and drill bit and is forced back out at the mouth of the borehole, along with the loosened drill cuttings, through the annular gap between the drill pipes and the borehole wall.Get price
