A wire rope 3/16 in or 1/4 in (4.8 mm or 6.4 mm) in diameter; used to
handle the inner tube of a wire-line core barrel. See also:cable
Long
Double-tube, swivel-type core barrel; available in various outside
diameters corresponding to sizes of diamond- and rotary-drill boreholes;
designed so that the inner-tube assembly is retractable. At the end of a
core run, the drill string is broken at the top joint so that an overshot
latching device can be lowered on a cable through the drill-rod string.
When it reaches the core barrel, the overshot latches onto the retractable
inner-tube assembly, which is locked in the core barrel during the core
run. The upward pull of the overshot releases the inner tube and permits
it to be hoisted to the surface through the drill rods; it is then emptied
and serviced and dropped or pumped back into the hole, where it relocks
itself in the core barrel at the bottom. Syn:wire-line barrel
Long
The act or process of core drilling with a wire-line core barrel.

In this method, digging tools or buckets are suspended on a steel cable
and lowered to the sediment surface, where they are loaded and retrieved.
Includes the use of drag-bucket and clamshell dredges, and generally to a
depth of not more than 500 ft (152 m) below sea level. Mero
The drilling of boreholes with wire-line core-barrel drill-string
equipment. Long
Drill rod having couplings that are nearly flush on the inside and
designed so that the inner tube of a wire-line core barrel and overshot
assembly can be run inside the rod. Long
A rod coupling designed for use on wire-line drill rods.
