REMOVALREMOVALREMOVALREMOVAL OF OF OF OF CUTTINGSCUTTINGSCUTTINGSCUTTINGS

� 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.

DisadvantagesDisadvantagesDisadvantagesDisadvantages� The method still requires the drilling and blasting

of relief holes in order to achieve the required slot dimensions.

Slot development using Alimak method

• The development of slot raises using the Alimakmethod 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 on 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 USINGCONVENTIONAL 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

SLOT DEVELOPMENT USINGCONVENTIONAL 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 drillngrequired 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.
