is the core cutting tool. As the drill bit penetrates through the material, it creates a core in its wake, entering the core barrel until its recipient tube is full, or the cores entry is impeded, at which time the sample recipient tube is removed, emptied of its core, replaced and drilling can resume.

Core sampling will consist of the borehole starting point or collar, the target and the path in between. Boreholes ranging from 48146 mm diameter, and depths of 33000 m share the following:

The diamond core drill The flushing circuit The drill rod string The core barrel The diamond tools

As a general rule; the larger the core diameter the better the core recovery.

2 .1 Core in the boxThe end users of exploration core drilling products are generally in the business of, providing representative and quality core samples to their customers.

Recovered core samples are used to extract vital information where chips or other data gathering techniques do not provide the level of confidence required to make decisions.

The quality of recovered core samples is of greatest importance, and is influenced by the personnel, capital and support equipment, diamond products, tools and accessories used in given ground conditions.

In The Hole tools, (ITH), represents only a small component of total project cost, but its selection and use have great significance.

Understanding the end user then, his goals and in particular his application, influences how efficient coring and commercial solutions are developed and implemented.

Core drilling basics

Core can be generally defined as a volumetric cylinder of material, created by the advancement of a rotating hollow centered diamond drill bit through a given in-situ formation and subsequently removed.Core recovery is a quantifiable measurement defined as the total linear amount of physical core sample extracted over the total linear advancement in a given borehole, expressed as a percentage. Recovery is often measured against a section of advance, typically in the target zone and/or for the entire borehole.

Length of core

Length of advance

Mechanically speaking, the core being created is encapsulated within and extracted by a retrievable sampling device, called a core barrel.

It is connected to a consumable coring drill bit, typically made with synthetic diamonds, which

CR (%) = x 100

72 - Efficient core recovery

Diamond drills come in many shapes and sizes. The drill, properly anchored at the borehole collar, primarily needs to transmit rotation, thrust and pullback forces.

Fluid is primarily required to cool and flush the cuttings from in front of the advancing diamond core bit and evacuating them from the borehole.

The flushing medium can be clear water or include needed additives, "muds", used to condition borehole integrity and complete the circuit.

The fluid flushing circuit can vary significantly, but typically consists of one or more pumps, the fluid media itself, the drill rod string, the available borehole annular area and the peripheral accessories for controlling delivery, treatment and handling.

Connected to the diamond drill, a straight rod string combined with smooth rotation and borehole conditioning will turn vibration free in the hole while transmitting the feed pressure to the cutting tool.

The core barrel is most critical to efficient core recovery.

The core barrel is sandwiched in between the drill rods and the diamond bit. Whether conventional or wireline, the design will typically be configured as a double tube system consisting of an outer tube and inner tube. While the outer tube rotates with the drill rod, the inner tube is meant to remain stationary during advancement.

As a general rule; the smoother the transmission of rotational force, the better the core recovery.

As a general rule; with deteriorating ground con-ditions, focus on the flushing circuit to improve core recovery.

As a general rule; proper care and handling of rods and a vibration free rotation, are your keys to improved core recovery.

Triple tube systems using a split inner tube are common in broken or friable ground where the flushing mediums pathway can wash away some of the sample before it makes its way into the inner tube with consequential effect on measurable re-covery. Triple tube systems use core lifter cases and diamond bits designed to direct the drilling fluid through the bit blank instead of through the bit throat preventing sample washing.

The diamond tools are the business end of the string and the bit in particular is a metallurgical marvel. The diamond bit ultimately cuts through the material that makes its way into the core barrel.

Crown profile, flushing, and guage design characteristics react differently with changes to rotation, thrust and flushing parameters.

As a general rule; ensure that bearings and wear parts are regularly serviced, and avoid deforma-tions, damaging blows and mishandling to the inner tube in order to improve core recovery.

As a general rule; choose the largest triple tube system possible in bad ground to improve core recovery.

As a general rule; choose bit designs that protect ID run out and that minimize back pressure and sample washing to improve core recovery.

83 - General application selection criteria

3 .1 Core barrelsApplying advanced technology to todays core drilling tools and processes is a science in itself. And its one in which Atlas Copco engineers have taken a leadership role. Conventional or wireline drilling, Atlas Copco drill rods, core barrels, accessories and casings are being constantly upgraded to exceed the expectations of todays diamond drilling contractors and mining companies around the globe.

Surface core barrels Atlas Copco offers a full range of surface application core barrels. Available in standard double tube designs with the option for easy conversion to triple tube configurations in broken ground.

Thin wall core barrels, used when ground conditions and drill rig selection are appropriate, offer the end user an opportunity to increase sample size within a nominal bore hole size.

Underground core barrels Pump in, or underground style double tube and double tube thin wall wireline core barrels are available for flatter and up hole applications where gravity does not permit unassisted movement of the inner wireline components. Designed with Atlas Copco attention to quality and performance, you can count on these products where you need to push the inner tube and overshot assemblies through the drill rod string using the circulating fluid. In addition, underground style core barrels include built in safety designs.

Conventional core barrels Conventional core barrels produce a larger core diameter compared to the equivalent wireline nominal size. Their rugged construction and design features ensure optimization of productivity in applications where the use of a wireline system is not practical or cost effective.

Conventional core barrels are typically used in shorter boreholes.

5 - Surface double tube wireline core barrel

Double tube wireline core barrels are the predominant core barrel configurations used in mineral exploration.

As a general rule, double tube core barrels are used in all but the most broken and friable ground conditions, and are designed for ease of use with drilling additives and loss control materials when required.

Surface systems are those where the overshots and inner tubes descend through the drill string under their own weight, and as such are normally used in borehole orientations between -90 and -45 degrees.

When selecting a surface double tube wireline core barrel and associated drill rod string, a 'bail' style water swivel and hoist plug is commonly chosen for use with surface style drill rigs using a main hoist to raise and lower the drill string.

Ensure that the adapter subs chosen mate to the chosen rod thread.

Triple tube wireline core barrels are the predominant core barrel configurations used in mineral exploration where gound conditions are generaly categorized as poor, are commonly friable and broken.

These designs permit ease of use with drilling addi-tives and loss control materials as these are typically required. The barrel uses an additional split inner tube to encourage an undisturbed sample recovery while corresponding diamond bit designs ensure minimum contact of the circulating fluid with the core sample maximizing core recovery.

Surface systems are those where the overshots and inner tubes descend through the drill string under their own weight, and as such are normally used in borehole orientations between -90 to -45 degrees.

When selecting a surface triple tube wireline core barrel and associated drill rod string, a 'bail' style water swivel and hoist plug is commonly chosen for use with surface style drill rigs using a main hoist to raise and lower the drill string.

Double tube thin wall wire line core barrels are used in select mineral exploration applications.

Using thinner walled cross sections for rods, tubes and diamond bit kerfs creates a larger core sample within nominal 'A' and 'B' bore holes. Their design allows for ease of use with less dense drilling additives when required, and are typically chosen for more competent ground conditions and for use with high speed drills having lower pull down forces.

By changing a handfull of components only, the NO2" configurations provide a marginally larger core sample, all the while using traditional N wireline drill rod

Surface systems are those where the overshots and inner tubes descend through the drill string under their own weight, and as such are normally used in borehole orientations between reintations between -90 to -45 degrees.

When selecting a surface thin wall double tube wireline core barrel and associated drill rod string, a 'bail' style water swivel and hoist plug is commonly chosen for use with surface style drill rigs using a main hoist to raise and lower the drill string.

Double tube wireline core barrels are the predominant core barrel configurations used in mineral explora-tion.

As a general rule, double tube core barrels are used in all but the most broken and friable ground condi-tions, and are designed for ease of use with clear water common in underground environments, or with drilling additives and loss control materials when required.

Underground systems are those where the overshot and inner tube assembly need be pumped under pressure through the inside of the drill string, and as such are normally used in borehole orientations between +90 to -45 degrees.

When selecting a underground double tube wireline core barrel and associated drill rod string, it is common that a automated drill is being used. A hoist plug may not be required for rod handling, and the water swivel will likely be a high speed type like the 18/0 with integrated drill rod connection. In addition, a stuffing box will be required to permit hydraulic propulsion of the overshot assembly.

It is possible that a 'bail' style water swivel and hoist plug may be chosen for use with surface hoist style drill rigs using a main hoist to raise and lower the drill string.

Underground double tube thin wall wire line core barrels are used in select mineral exploration applications.

Using thinner walled cross sections for rods, tubes and diamond bit kerfs creates a larger core sample within nominal 'A' and 'B' bore holes.

By changing a handfull of components only, the NO2-U" configuration provides a marginally larger core sample, all the while using traditional N wireline drill rod.

Their design allows for ease of use with clear water common in underground environments or less dense drilling additives when required, and are typically chosen for more competent ground conditions and for use with high speed drills having lower pull down forces.

Underground systems are those where the overshot and inner tube assembly need be pumped under pressure through the inside of the drill string, and as such are normally used in borehole orientations between +90 to -45 degrees.

When selecting a underground thin wall double tube wireline core barrel and associated drill rod string, it is common that a automated drill is being used. A hoist plug may not be required for rod handling, and the water swivel will likely be a high speed type like the 18/0 with integrated drill rod connection. In addition, a stuffing box will be required to permit hydraulic propulsion of the overshot assembly. While not as common, it is possible that a surface hoist style drill rig using a main hoist to raise and lower the drill string will be used, requiring a 'bail' style water swivel and hoist plug.
