Casings are installed into the overburden basically for two different reasons: 

1. To create a conduit through the overburden for example;

● gas, oil, water and geothermal wells

● utility lines

● starter casings for exploration

● routing casings

2. To create foundation and support structures such as;

● piles

● Ore poling, pipe roofs

● ground stabilization

● Anchors

 

Depending on the use of the casing it is either left in the hole permanently or retrieved by pulling out. Symmetrix range includes systems for drilling both permanent and retrievable casings.

In case of the permanent casing the ring bit is sacrificed and left in the bottom of the hole, while drilling retrievable casings all system components are retrieved for re-use. 

Casing Tube is used with the system must have an outer diameter smaller than the hammer diameter, (this is to allow the cuttings to pass unrestricted back up the casing). The length of the rods should be identical to the length of the casings, this will guarantee the spanner flats on each joint are clear of the casing.
