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. 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 used for reprocessing, contouring land, and as a construction aggregate for buildings and roads. Mine tailings are reused for producing clay, tiles, glass, and concrete. Mine water is treated and then used for dust and particulate suppression, agricultural/industrial use, and as a coolant.
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.
