FAQ:

1. What is odex drilling?
ODEX is an adaptation of the air-operated down-the-hole hammer. It uses a swing-out eccentric bit to ream the bottom of the casing. Cuttings blow up through the drive sub and casing annulus to a swivel conducting them to a sample collector or onto the ground. Rapid removal of cuttings.


2. Where do they put overburden?

The most common use for the large volumes of overburden produced by a surface mine is to remediate and reclaim the area where it was first removed. Putting the sand, rock, and clay back where it came from helps rebuild the level of the soil so that plant life can return.


3. How does a casing advancer Work?
The Casing Advancer has been designed to allow drilling and casing to be carried out at the same time as one integral operation. This feature eliminates the need to drill the large diameter hole with a Rock Bit, pull the drill rod string and Rock Bit from the hole and then ream the casing back into the hole.
