to

as

Results

Viewing

the

illustration

on

the

top

right,

this

represents

a

blasting

pattern

that

was

not

matched

to

either

explo

-

sive properties as well as ore properties.

Previous

blasting

practices

were

based

on

using

100

mm

(4

in)

diameter

blastholes

and

a

blasting

pattern

spacing

of

2.3

m

(7.5

ft)

and

burden

of

2.0

m

(6.6

ft).

Results

were

consistent

with

overbreak

and

dilution

along

with

not

meeting

the

<

400

mm

(16

in)

fragmentation

profile

specification.

The

natural

response

of

the

engineering

depart

-

ment

was

to

consider

pulling

the

pattern

in

further

with

the

realization

that

powder

factors

would

increase.

It

was

hoped

that

increasing

the

powder

factor

would

solve

the

fragmentation

concerns.

When

fragmentation

is

poor

and

found

to

be

undesirable,

the

natural

response

of

many

engineering

departments,

is

to

increase

the

powder

factor

and

thus

the

overall

available

explosive

energy

to

mitigate

problems.

Alternatively,

it

has

been

proven

that

this

action

usually

exacerbates

blasting

problems.

To

appeal

to

the

mine

engineering

department

for

devising

an

alternative blasting plan.

AEGIS

Break

Analyzer

was

able

to

simulate

both

the

conditions

generating

poor

muck

and

overbreak

as

well

as

come

up

with

pattern

designs

that

eliminated

overbreak

and

dilution

as

well

as

generating

muck

below

the

400

mm passing limit.

“Given

that

the

mine

does

not

have

a

primary

crusher

underground,

the

fragmentation

had

to

be

less

than

400

mm,

the

opening

dimensions

of

their

grizzly.

As

a

result

of

these

steps,

the

blast

fragmentation

was

impeccable

throughout

the

mucking

process.

The

stope

was

excavated

under

the

barrier

of

the

coveted

10

cent

dilution.”

Isosurface Meshes and CMS Surveys

Current

blasting

practices

for

underground

blasting

operations

require

drilling

holes

of

a

specific

diameter

and

with

a

very

definite

ring

geometry

that

is

usually

oblique.

This

produces

a

drill-hole

which

is

loaded

with

and

sequenced

to

generate

that

should

be

Using

below.

AEGIS

can

do

more

than

AEGIS

is

an

optional

module

that

provides

advanced

blast

simulation

and

modeling

tools,

which

are

incredibly

valuable

for

optimizing

blasting

opera

-

tions.

For

example,

a

cavity

monitoring

survey

(CMS)

can

be

used

to

calibrate

the

blast

simulation

model.

The

model

can

then

be

used

to

predict

the

final

excavation

break

and,

if

the

fragmentation

characteristics

of

the

various

rock

types

are

known,

the

predicted

amount

of

fines

and

oversize

can

be

calculated.

This

allows

the

blasting

to

fine-tune the blast design for optimal results.

CMS Surveys and Modeling Dilution

Blast

access

to

techniques

that

have

traditionally

only

been

available

to

By

definition,

dilution

is

valueless

rock

that

is

removed

along

with

the

ore

in

the

mining

process,

subsequently

lowering

the

grade

of

the

ore

and

thus

lowering

its

hoisted

value.

Recovery

refers

to

the

vol

ume

of

ore

recovered

within

an

ore

boundary.

The

ore

body

is

fractured

using

explosives

within

this

boundary

and

not

beyond.

Most

underground

mines

plan

for

90

percent

recovery

and

10

percent

Over-break

is

the

amount

of

fracturing

from

blasting

that

extends

past

Thus,

predicting

over-break

as

-

sumes significant importance to accurately designed site-specific blasts for minimizing host rock damage.

Modeling

Advanced Costing

A cost estimation model is used to predict the cost of a scenario using known and generalized costs.

Users

enter

the

cost

information

of

explosives,

primers,

detonators,

etc.,

as

well

as

estimated

operational

costs.

AEGIS will provide calculated costs with respect to blasts, rings, stopes, etc.

A

cost

model

approach

not

only

allows

a

planner

to

estimate

the

cost

of

a

project

using

past

knowledge,

but

also to compare the difference in cost with regards to different blast patterns and different products.

The

cost

model

can

be

as

complex

or

as

simple

as

required.

The

user

can

explore

the

resulting

costs

that

have

been calculated for a scenario through a comprehensive cost screen and through extensive reporting.

Get totals for specific products or cost types, or get aggregate costs for rings, ringsets, holes etc.

Aegis Cost Model

The

model

is

a

single

unit

that

keeps

track

of

all

desired

costs

that

are

to

be

applied

to

a

scenario.

It

allows

the

user

to

define

costs

associated

with

consumables

(explosives,

primers,

detonators)

and

variable

costs

that

can

in¬clude costs in terms of cost per length of hole drilled; cost per ring; cost per hole; or cost per ring set/stope.

Multiple

cost

models

can

be

created

for

different

financial

periods

to

track

the

cost

of

products,

and

their

ef

-

fects

on

a

scenario.

Users

can

define

the

currency

symbol

for

each

cost

model,

and

all

costs

are

assumed

to

be

entered in that currency. The items in the cost model must be uniquely represented by the Item string.

The

group

field

is

simply

used

to

sort

the

costing

items

and

for

reporting

purposes.

There

are

some

database

items

such

as

explosives

where

the

explosive

name

is

not

enough

to

uniquely

identify

the

cost

item

because

there would be different costs depending on the package size and diameter of explosive.

The

Item

name

is

constructed

in

such

a

way

so

that

all

relevant

information

is

displayed,

and

the

item

name

is

unique.

For

example,

BLASTEX

[100

mm]

would

be

used

to

represent

the

explosive

Blastex

with

a

charge

diam

-

eter of 100 mm.

The same technique can be applied to any database item where the name is not a unique identifier.

Scenario Costs and Reporting

When

is

applied

to

a

scenario,

the

rules

defined

in

the

cost

model

are

applied

to

each

item

in

the

scenario.

For

example,

a

cost

rule

for

surveying

holes

has

a

normalized

cost

of

$2550

per

ring.

When

the

costs

for

the

scenario

are

calculated,

$2550

will

be

added

to

each

ring

to

account

for

surveying

costs,

in

other

words

$250

will

be

multiplied

by

the

number

of

rings

in

each

stope

of

the

scenario

to

arrive

at

a

final

cost

to

survey

the holes. This is regardless of how many holes are in the ring.

Once

a

cost

model

is

applied

to

a

scenario,

the

has

the

option

of

getting

a

Best Practices

AEGIS designs precision ring blasting software employing a physical model that matches energy states of explosives and stress distributions utilizing both ore properties and explosive properties for precision break. If explosives products are used in advanced pattern designs, mining companies can have significant savings downstream. Everything is related to that first break. Using AEGIS Designer can give an engineer or planner an drilling pattern in seconds for quick appraisal. Easily edit holes and explosive charges without having to redo everything or start from scratch … again. Complete a whole stope at once or complete selected stope volumes. No complicated slicing to deal with as in the past. Block models can be imported and stored within an AEGIS project. Legend templates can be added to AEGIS settings for specific fields within a block model.

Doing It Right

Downstream processes rely heavily on material handling based on fragmentation. Improper blast design directly affects bottom line economics. AEGIS Designer , Analyzer and Break Analyzer were developed for underground mining engineers and planners, for automatically generating ring designs and charging layouts for entire stopes within seconds. Change or edit a completed design in seconds. No undoing of past work. AEGIS radically changes the way underground long-hole ring design is done and represents the future of underground drill and blast design. AEGIS demonstrates how holes loaded with gassed emulsions can calculate density variations for emulsion formulae based on load weight and density within a blasthole. AEGIS uses measured explosives property data in conjunction with measured rock/ore property dynamic modulus and strength values.

Education

Using AEGIS, pattern designs are based on understanding how energy distribution, using strategically placed blast-holes drilled in complicated orebody geometries, can influence blast pattern design. Knowledge concerning the use of explosives as well as case histories and other notes are taken from a broad range of sources including authors skilled in the art as well as personal experience. AEGIS provides an extensive Knowledgebase . Users can use the knowledgebase for developing their level of understanding regarding the physics of the detonation and fragmentation process using today’s advanced explosives and electronic detonators. Tutorials are available for all AEGIS modules. Use our extensive WIKI list of links and mining definitions to further extend your knowledge around explosives and blasting.

Sequencing a Multihole Blasting

Operation

AEGIS Analyzer Ring Planning Plan rings in seconds along with reports. Planner break as well as break calculated using Break Analyzer can be used to determine overbreak and dilution. Isosurface Meshes and CMS Surveys Current blasting practices for underground blasting operations require drilling holes of a specific diameter and with a very definite ring geometry that is usually oblique. This produces a drill-hole pattern which is loaded with explosives and sequenced to generate a fragmentation profile that should be matched to materials handling equipment for a mining method. Using isosurfaces for radial break that a planner may estimate to visualize break are shown below. AEGIS can do more than design long-hole drilling layouts. AEGIS Analyzer provides advanced blast simulation and modeling tools, which are incredibly valuable for optimizing blasting operations. A cavity monitoring survey (CMS) can be used to calibrate the blast simulation model. The model can then be used to predict the final excavation break and, if the fragmentation characteristics of the various rock types are known, the predicted amount of fines and oversize can be calculated. Allows the blasting engineer to fine-tune the blast design for optimal results. CMS Surveys and Modeling Dilution Blast analysis uses proven blast modeling algorithms including Klein, Holmberg-Persson and Liu-Katsabanis, which provide drill and blast engineers’ access to analysis techniques that have traditionally only been available to specialized blasting consultants. Dilution is valueless rock that is removed along with the ore in the mining process, subsequently lowering the grade of the ore and thus lowering its hoisted value. Recovery refers to the volume of ore recovered within an ore boundary. The ore body is fractured using explosives within this boundary and not beyond. Most underground mines plan for 90 % recovery and 10 % dilution. Overbreak is the amount of fracturing from blasting operations that extends past ore boundaries. Predicting overbreak assumes significant importance to accurately design site-specific blasts for minimizing host rock damage.
Four Views - 3D, Ring Section, Plan and Longitudinal Section
Kinetics AEGIS analyzes or diagnoses blasting patterns based on a stress reflection principle and a unit charge blasting geometry. There are five analytical blasting calculators as well as one main Blast Design workflow. These tools permitt engineers and planners to view the effects of explosive types, rock/ore parameters and stress generation on ring blasting as well as discovering how varying specific parameters and properties of both explosives and rock/ore types influence blast pattern design. Objectives Benchmark current blasting practices as well as provide insight into new patterns and practices. Based on dynamic explosive properties and dynamic rock properties, Break Analyzer matches the explosive detonation state (shock/brisance) and explosion state (gas expansion and heave) energies in order to maximize ore recoveries and minimize dilution. Target fragmentation can be optimized and sized for haulage equipment, potentially minimizing (or eliminating) primary crusher requirements in conjunction with reducing associated crushing costs. AEGIS Break Analyzer is used on the premise that current blasting operations can be improved through careful control of the application of explosive energy distributed throughout an orebody to provide maximum recovery with absolute minimum dilution. The objective is to recover ALL the ore and LEAVE the support rock. An Information and Training Tool Focus is to get things right the first time, without having to go through an experimental phase searching for what works best.

More attention is being placed addressing the myriad geometries presented by complicated orebody shapes and grades. AEGIS Break Analyzer software has been specifically designed to enable many ‘what-if’ scenarios to be tested and applied to complex orebodies in seconds to find perfect ring layouts optimized for highest recovery at the lowest cost. Drilling layouts, charging plans and blasting letters can be reported on paper using MS PowerPoint formats by defining templates and then manually adding any notations or warnings as required.

AEGIS

will

provide

calculated

costs

with

to

blasts,

rings, stopes, etc.

A

to

of

a

project

using

past

AEGIS Cost Model

The

model

is

a

single

unit

that

keeps

track

of

all

desired

costs

that

are

to

be

applied

to

a

scenario.

It

allows

the

user

to

define

costs

associated

with

consumables

(explosives,

primers,

detonators)

and

variable

costs

that

can

in¬clude

costs

in

terms

of

cost

per

length

of

hole

drilled;

cost

per

ring; cost per hole; or cost per ring set/stope.

Multiple

cost

models

can

be

created

for

different

financial

periods

to

track

the

cost

of

products,

and

their

effects

on

a

scenario.

Users

can

define

the

currency

symbol

for

each

cost

model,

and

all

costs

are

assumed

to

be

entered

in

that

cur

-

rency.

The

items

in

the

cost

model

must

be

uniquely

repre

-

sented by the Item string.

The

group

field

is

simply

used

to

sort

the

costing

items

and

for

reporting

purposes.

There

are

some

database

items

such

as

explosives

where

the

explosive

name

is

not

enough

to

uniquely

identify

the

cost

item

because

there

would

be

dif

-

ferent

costs

depending

on

the

package

size

and

diameter

of

explosive.

The

Item

name

is

constructed

in

such

a

way

so

that

all

rele

-

vant

information

is

displayed,

and

the

item

name

is

unique.

For

example,

BLASTEX

[100

mm]

would

be

used

to

repre

-

sent

the

explosive

Blastex

with

a

charge

diameter

of

100

mm.

The

same

technique

can

be

applied

to

any

database

item

where the name is not a unique identifier.

Cost Model Manager

Manager

allows

the

user

to

create,

duplicate,

delete,

edit,

and rename cost models in one comprehensive form.

Cost

models

are

represented

by

a

tree

structure

that

is

tied

to the cost model folder in the file system.

The

user

can

click

and

drag

cost

models

into

or

from

folders,

create

new

folders

and

organize

them

as

one

sees

fit.

The

folders can also be renamed.

All

opened

cost

models

will

appear

in

tab

allowing

the

user

to view/edit multiple cost models at the same time.

Scenario Costs and Reporting

When

a

cost

model

is

applied

to

a

scenario,

the

rules

de

-

fined

in

the

cost

model

are

applied

to

each

item

in

the

sce

-

nario.

For

example,

a

cost

rule

for

surveying

holes

has

a

normalized

cost

of

$2550

per

ring.

When

the

costs

for

the

scenario

are

calculated,

$2550

will

be

added

to

each

ring

to

account

for

surveying

costs,

in

other

words

$2550

will

be

multiplied

by

the

number

of

rings

in

each

stope

of

the

sce

-

nario

to

arrive

at

a

final

cost

to

survey

the

holes.

This

is

re

-

gardless of how many holes are in the ring.

Once

a

cost

model

is

applied

to

a

scenario,

the

user

has

the

option

of

getting

a

detailed

look

at

the

costs

of

the

entire

scenario

using

the

scenario

costs

form.

The

purpose

of

this

window

is

to

provide

the

user

with

a

quick

summary

of

the

costs

(summary

tab)

and

in

order

to

examine

the

costs

that

are applied using various table views.

There

are

various

predefined

costing

tables

that

are

accessi

-

ble

from

the

top

ribbon

bar.

They

include

all

costs,

product

quantities, blast costs, ring costs and custom table.

For

all

table

views,

a

footer

indicates

the

number

of

rows

and

the

total

cost

of

the

items

in

the

table.

Also,

any

of

the

table

headers

can

be

dragged

to

the

group

by

row

to

create

a

different

view

of

the

same

table.

This

allows

the

user

to

group

by

any

property

and

receive

updated

totals

for

each

group.

Report

tables

for

different

types

of

costing

information

are

available

in

all

report

builders

and

all

types

of

contexts

in

AEGIS.

Product

costs

(explosive,

detonator,

primer

and

all

prod

-

ucts)

are

available

in

each

of

the

contexts

(project,

sce¬nario, ringset, ring, slot and blast).
