Comparing Available Sys tems

Some basic differences

• Basic sys tem – Direct Control – valves , hoses, noise and heat in operators cabin, inefficient , no drilling controls, difficult to trouble shoot, costly to operate, mechanical angle setting, no depth control, requires shot layout

• Combination system Hydraulic / Electronic – valves, hoses, reduced noise and heat in operators cabin, adjustable drilling controls, some trouble shooting assistance, more efficient than basic, electronic angle and depth control, requires shot layout

• CAN Bus sys tem – Greatly reduced number of valves and hoses, no noise and heat in operators cabin, Fully programable drilling control system, full diagnostic capability, extremely efficient, with GPS installed accurate angle and depth setting and recording, no shot layout required.


• Asa drill manufacturer we see a huge swing in the market with more and more operators ready to embrace newly availabe technology.

• This move has been driven by several factors, the key ones being – A severe shortage of skilled drillers – Safety concerns with the Drilling and Blasting process – Operator Safety concerns – Overall production costs

Technology Integrated with drilling


Advantages of “Smart drills” over conventional configuration

• Advanced drilling control sys tem – programable to any conditions, smooth proportional adjustment, optimum performance.

• Fuel savings with intelligent control of compressor load and engine rpm

• Consistent productivity through automated drilling and rod handling

• Improved availability- Reliable componentry and inbuilt diagnostics


Drilling Automation

• The rig drills automatically and to the desired depth, which makes it less dependent on the operator

• Automatic overburden drilling gives stable holes • The rig adds and retracts tubes automatically on

DTH, adds only on TH • Less wear on consumables and the rig itself • More holes per shift



Intelligent Sys tems gives substantial fuel savings • Automatic compressor load control, according to

demand • Automatic engine RPM control according to demand • Potential fuel saving 20% on DTH and 50% on TH

compared to standard configured machines

Auto drill positioning

• Semi automatic positioning of the feed, both sideways and forward/backward

• Having the correct angle is vital for the overall effectiveness of the mine operation.

• Example:1 degree alignment error on a 12 m bench gives a 21 cm error at the bottom of the hole

Hole Navigation System To improve your quarrying process you need a comprehensive strategy that includes every step of your operation:

□ Planning □ Drilling □ Analyzing □ Blasting □ Loading and hauling □ Crushing

With accurate planning and correct drilling there is money to be saved.


Quarrying p rocess Improve your quarrying process requires a comprehensive strategy that includes each step of your operation:

□ Planning □ Drilling □ Analyzing □ Blasting □ Loading and hauling □ Crushing

With good planning and accurate drilling, efficiencies can be improved and costs reduced


CHALLENGES IN DRILLING

□ Drilling is the first steps in the process and it effects the rest of the operation

□ There are several challenges to overcome. What may look right on the surface, can be a completely different story underneath


CRITICAL TO DRILLING

□ Drilling Accuracy

– Accurate Shot Layout

– Accurate Spacing / Burden

□ Hole Depth – Drilled to the correct depth

□ Hole Angle – Every hole drilled to the desired angle

□ Blast Direction – Holes facing the correct direction

MAIN BENEFITS OF HNS

□ Increased safety for operator and surveyor.

□ High-quality drilled holes to correct depth.

□ Improved productivity through a smarter process.

□ Documentation

Hole Navigation System


SATELLITE-BASED PRECISION

□ The system guides the operator easily to the correct position, using GNSS (Global Navigation Satellite Systems).



SATELLITE-BASED PRECISION □ The normal error of a GNSS-system

(GLONASS or GPS, the system uses both) is around 5 meters.

□ The system needs correction data to minimize the error. This is send by radio from a base station to the rig.


GHNSS +-5 mcm

Base s ta tion


SATELLITE-BASED PRECISION □ The base station is placed on a known point.

□ From its fixed position it can detect the actual error and transmit the correction data to the drill rig.

□ By correcting the GNSS measurement fault, we can get an accuracy to within +/– 5 centimeters.


Base s ta tion


• With ROC Manager, or similar office software, you plan the blast for best outcome. Here you set the burden, spacing and hole length.

• Now there is no need to enter unstable and hazard areas to mark holes.

OUTSTANDING RESULTS – AS PLANNED



OUTSTANDING RESULTS – AS PLANNED • The hole angles and the blasting

direction are also set in the drill plan, which is then transferred to the drill rig’s Hole Navigation System.




HOLE DEPTH ACCURACY

□ Showing holes drilled to the same depth using the drill a s reference

AUTOMATIC CORRECTION

□ Corrections are made if deviations from the original plan are required

□ The system recalculates the angles so you always get to the correct end coordinates.


Alw a ys c o rre c t depth


PARALLEL HOLES TO THE CORRECT DEPTH □ Drilling to the correct depth is automatic since

the system has the 3D coordinates of the hole bottom.

□ The 3D position of the drill bit is aligned with the correct coordinates at all times.


AUTOPOS

□ AutoPos option ensures that the drilling angle is always set a s planned, regardless of drilling position.

□ By pressing a button the feed adjusts itself automatically to the angles defined in the drill plan.



TWO ANTENNAS FOR CORRECT BLAST DIRECTION

Rear antenna Blast s een from above when aiming with HNS□ The two antennas allow the system

to calculate a baseline direction.

□ Using the baseline direction, the system can easily calculate the angles and adjust the feeders to the correct blast direction.


STAY IN CONTROL WITH FOLLOW-UPS• When the drill plan has been drilled, you run

the information that the rig has gathered to analyze the blast.

• Compare the planned holes with the drilled holes and look for variations in the rock with Measure While Drilling (MWD).

• With this information you can control the blast by making sure the right amount of blasting material is being used.




Blast optimizing Planned/drilled holes Data of drilled hole.


PARALLEL HOLES




Statistics Analysis of drill efficiency , tracks drilled footage, percussion time, number of holes, tramming time, for a selected time period.

Total footage drilled



MWD data The rig saves different drill parameters that the software combines to a hardness chart.



Safety A well-controlled process means less risk for flying rocks. It also eliminates the need for the operator/surveyor to mark the bench. This saves time a s well a s increases worksite safety.



High-quality drilled holes to correct depth Enables high-quality placement of holes, hole angles and depths. This delivers better blast results, better fragmentation and improved loadability with less explosives.

Also it provides Shot documentation



Productivity

□ A more uniform bench floor will be achieved resulting in better loading.

□ A more uniform drill pattern will result in a higher quality blast result.

□ That, in turn, will deliver better fragmentation to the crusher.

□ Good fragmentation can increase crusher throughput.
