FAQ:
1. What is odex drilling?
The air-operated down-the-hole hammer is adapted as ODEX. It reams
the bottom of the casing with a swing-out eccentric bit. Cuttings
emerge via the casing annulus and drive sub, passing through a
swivel and onto the ground or a sample collector. Quick removal of
the cuttings.
2. What is Symmetrix drilling?
Previously known in our industry as Concentrix, the updated
Symmetrix system allows for the simultaneous casing and drilling of
a hole. The system consists of three main components: pilot bit,
ring bit (reamer) and casing shoe
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.
4. Where does overburden go during a mining operation?
Overburden is employed as a building and road construction
material, for reprocessing, and for contouring land. Reclaimed mine
tailings are used to make concrete, glass, tiles, and clay. After
being cleaned, mine water is used as a coolant, in industry and
agriculture, and to control dust and particulates.
5. How deep can a water well be drilled?
Drilling a Water Well for household use will usually range from
about 100 feet to 500 feet deep, but... When drilling a new well
for your home or business, the depth of the well depends on the
geology and underground water levels of the area.
