REMOVAL REMOVAL REMOVAL REMOVAL OF OF OF OF CUTTINGS CUTTINGS CUTTINGS CUTTINGS

Cuttings normally don’t need to be removed with a scoop on a 25 – 30m raise, provided:

• The cuttings can be washed away from the drill after every rod.
• Access to the drill can be maintained so that the drill can easily

be moved once the hole has been completed. If access to the front of the drill is available with a scoop, we do like to remove the cuttings periodically.

Primary slots can be developed using Machines Rogers’ V-30 boring head and a conventional ITH drill. The 762mm diameter V-30 hole provides the relief required into which to blast the helper holes required to achieve the required slot dimensions. A typical 25 meter slot can be achieved in 1 to 3 shots depending on drilling accuracy and blaster proficiency.

A typical 1,8M x 1,8M , 25 meter length slot can be completed in 8 to 9 shifts. The use of an ITH drill will ensure drilling accuracy over long hole lengths. The V-30 can be used to develop 35 meter slots when drilling up, and 45 meters when drilling down.

Setting up the ITH drill in the stope in preparation for V-30 drilling does not require any special installation such as concrete pad or slashing the back. An experienced ITH driller will readily learn and master V-30 drilling. Training the local personnel can be achieved easily in relatively short time frame. In addition to developing the slots, the ITH drill can be used for all other drilling requirements such as: Production drilling Service hole drilling Paste fill hole drilling

Advantages of utilising the V- 30 boring head for slot development

Assurance that the slot will be successful ,with low risk of failure ,such as associated with conventionally blasted slots Ease of use and operator training relatively simple. Ability to use the ITH drill to accomplish other drilling requirements; production & service hole drilling. Speed by which the primary slots can be developed in comparison to other methods. Equipment setup and moving without special installations such as required for Raise Boring (concrete base) or Alimaks. Capacity to develop blind slots (drilling up) without the requirement for an upper level. Disadvantages Disadvantages Disadvantages Disadvantages The method still requires the drilling and blasting

• f relief holes in order to achieve the required

slot dimensions.

Slot development using Alimak method

• The development of slot raises using the Alimak

method requires specialised equipment and an experienced labor force.

• The installation of Alimak equipment is

complicated and labour intensive.

• Miners experienced in Alimak mining are difficult

to find and/or train and require:

• Specialised training with Alimak installation.
• Experience using ‘Stopper’ drills.
• Experience in raise blasting.
• Completing a typical 2,0M x 2,0M, 25 meter

length slot can require 20– 22 shifts depending

• n the type of installation chosen.

Slot development using a conventional Raise Bore

• Slot development using a conventional raise boring

machine involves sophisticated equipment requiring a specialised labour force.

• Raise bore machines are normally operated by a mining

contractor with highly trained raise bore operators.

• Training a proficient raise bore operator is a lengthy

process..

• Training the local work force on the use of this type of

equipment is a long a repetitious

• The equipment is expensive and will be uniquely

dedicated to the slot development. This equipment will not be used for other drilling requirements such as; production drilling.

• This type of equipment does not typically have the

capacity of drilling blind up holes.

Slot development using a conventional Raise Bore

• Development of a typical 1,8M x 1,8M, 25 meter in

length slot using a 42’’ reamer can require 10 – 12 shifts:

• Site preparation, installation of concrete base

and equipment installation: 3 shifts.

• Drilling pilot hole and installing reamer head:

1 shift.

• Reaming to 42 inches: 3 shifts.
• Drilling 4 ½’’ holes: 2 shifts.
• Blasting: 2 shifts.
• Demobilisation: 1 shift.

SLOT DEVELOPMENT USING CONVENTIONAL DRILLING AND BLASTING

• The development of a primary slot using

this method requires an experienced labour force.

• The success of a slot using this method

will first of all be driven by the accuracy of drilling.

• This method requires attentive

drillers and the right choice of drilling equipment.

• If slots are longer than 15 meters

serious consideration should be given to choosing an ITH drill.

• Hole deviation of more than 3% will

increase the possibility of failure.

• Blasting the slot using this method will require an experienced

blasting team.

• Blasting a slot is not an exact science, and the blaster will have to

adjust his method and bring required changes after each blast.

1,8 M 1,8 M 1,8 M

SLOT DEVELOPMENT USING CONVENTIONAL DRILLING AND BLASTING

• A typical 1,8M x 1,8M, 25 meter slot will

require 8 to 10 blasts, depending on the proficiency of the blaster.

• The total slot development will re quire

13 – 15 shifts, provided no major problems are encountered.

• A missed blast will require specific and

detailed operating procedures in order to attempts to recover the slot.

• Standard operating procedures will need to be developed in order

to minimise the recovery risk.

• When explosives remnants are suspected to be present, all drillng

required to recover the slot will have to be carried out with remote drilling.

• In certain situations, a failed slot will have to be abandoned and re-

drilled at another location.
