FAQ:
1. What is hole hammer?
Pneumatic down-the-hole (DTH) hammer is a pneumatic drilling tool using compressed air as a power source. It is suitable for drilling in pebble, gravel, and hard rock strata. It is often used in building pile foundation construction, bridge, mining, geological exploration, hydrological wells, and other fields.
2. What is overburden fill?
Overburden Soil is a general, unprocessed, fill material that can contain a variety of different materials, depending on where it is sourced. Overburden Soil can contain sand, rocks, clay and stones, and will typically lack the organic material and nutrients found in topsoil.
3. How far can you directional bore?
What are the minimum and maximum lengths of crossing? Maximum lengths and hole diameters are determined by project specific geotechnical conditions however effective outside range for heavy rig horizontal directional drilling is 3,000 m
