Abrégé anglais


In an integrated Bulk Materials Handling system for a mining, preparation and
transportation process method, a calculation method and template procedure
called
"Operating System Calculation Method for Mining" using numerical simulation of
each
functional process flowsheet step to incorporate decoupling and redundancy

selection of
required equipment types and quantities including mobile excavators, mobile
crushers,
diesel powered haul trucks, overland (O/L) conveyors, O/L conveyor belt
loaders, belt
conveyors, surge hoppers and surge bins using sequentially integrated time and
motion
algorithms and calculation subroutines from the science of Bulk Materials

Claims
THE EMBODIMENTS OF THE INVENTION FOR WHICH EXCLUSIVE PROPERTY AND PRIVILEGE
RIGHTS
ARE DESCRIBED AND CLAIMED ARE AS FOLLOWS:
1. In an integrated Bulk Materials Handling system for a mining, preparation
and
transportation process method, a calculation method and template procedure
called
"Operating System Calculation Method for Mining" using numerical simulation of
each
functional process flowsheet step to incorporate decoupling and redundancy
strategies for
enhanced availability, improved surge storage strategies and quantities and
selection of
required equipment types and quantities including mobile excavators, mobile
crushers,
diesel powered haul trucks, overland (O/L) conveyors, O/L conveyor belt
loaders, belt
conveyors, surge hoppers and surge bins using sequentially integrated time and
motion
algorithms and calculation subroutines from the science of Bulk Materials
Handling so as to
model and optimize the physical handling of the upstream process flowsheet
steps of mined
ores feeding subsequent ore processing facilities to meet a mandated daily
production
requirement.
2. As in Claim 1 the calculation method and template procedure being used in
the context of
the mineable oil sand operations of northern Alberta, Canada for application
to
conventional process flowsheets of the oil sand industry and the simplified
process
flowsheet of Canadian patent 2,876,770.
3. As in Claim 1 the calculation method and template procedure being
computerized and using
a combination of actual and estimated data inputs from a mine owner's
representative or
his engineer.
4. As in Claim 1 wherein a higher availability is obtained for a mining,
preparation and
transportation process by decoupling of otherwise series-connected process
steps and
adding one or more redundant parallel equipment means having the same
functionality at
each process step; in which availability is defined as "actual operating time
divided by
scheduled operating time";
high availability for the overall process enabling an integrated calculation
subroutine to
apply small oversizing factors to the design, energy requirements and
specifications of
equipment productive capacity at each step of the process flowsheet.
5. As in Claim 1 an integrated calculation subroutine of the "Operating
System Calculation
Method for Mining" to calculate an appropriate surge hopper capacity for
feeding a mobile
crusher when paired with a mobile excavator, the mobile crusher feeding ones
of a mine
haul truck fleet; enabling a decoupling of the mobile excavator's
functionality of digging oil
sand from the mobile crusher's functionality of crushing and loading haul
trucks with oil
sand and increased productivity of each of the mobile excavator, the mobile
crusher and the
haul trucks.
Page 10

Claims
6. As in Claim 1 the use of sequentially integrated time and motion
algorithms and calculation
subroutines of the "Operating System Calculation Method for Mining" to
calculate an
incremental surge capacity of prepared oil sand being transported by the haul
trucks to the
surge bin enabled by inserting a mobile crusher between the mobile excavator
and the haul
trucks; thus facilitating a smaller surge bin to be implemented in the
flowsheet with no loss
of functionality to meet the mandated daily production requirement of
downstream
processing facilities .
7. As in Claim 1 an integrated calculation subroutine of the "Operating
System Calculation
Method for Mining" to calculate appropriate productive capacity specifications
of an O/L
belt conveyor added to the process flowsheet to partially decouple haul truck
functionality
from surge bin functionality as a redundant transportation link and source of
incremental
surge capacity of oil sand discharging into the surge bin.
8. As in Claim 5 an integrated calculation subroutine of the "Operating
System Calculation
Method for Mining" to estimate and select an appropriate crushing rate
capacity
specification for the mobile crusher feeding ones of a mine haul truck fleet;
enabling a
decoupling of the mobile crusher's functionality of crushing oil sand from the
mobile
excavator's functionality of digging oil sand.
9. As in Claim 1 a time and motion algorithm of the "Operating System
Calculation Method for
Mining" to estimate mine haul truck load cycles per hour using factors
including mobile
excavator productivity; load factor per bucket; load factor per haul truck
box; oil sand bulk
density in an as-mined condition; oil sand bulk density in an as-crushed
condition; mobile
excavator bucket passes per haul truck load; haul truck travel speed empty;
haul truck travel
speed loaded; haul truck travel distance; haul truck loading time and haul
truck unloading
time.
10. As in Claim 1 an integrated calculation subroutine of the "Operating
System Calculation
Method for Mining" to estimate quantities of independent mobile excavators
paired with
mobile crushers required to meet a mandated daily production requirement; the
calculated
number of mobile excavators paired with mobile crushers providing multiple
process
flowsheet redundancies to each other.
11. As in Claim 1 using sequentially integrated time and motion algorithms and
calculation
subroutines of the "Operating System Calculation Method for Mining" to
estimate
quantities of independent mine haul trucks required to meet a mandated daily
production
requirement; the calculated number of haul trucks providing multiple process
flowsheet
redundancies to each other.

Claims
12. As in Claim 8 for excavators and Claim 9 for haul trucks, an integrated
calculation subroutine
of the "Operating System Calculation Method for Mining" to calculate the
associated
number of direct operating personnel requirements for mobile excavators with
mobile
crushers and haul trucks, respectively.
13. As in Claim 1 the set of sequentially integrated time and motion
algorithms and calculation
subroutines of the "Operating System Calculation Method for Mining" to
calculate expected
non-productive idle time for the excavator and mobile crusher so as to inform
a mine
owner's decision as to sparing and redundancy strategies for obtaining
additional mobile
excavator and mobile crusher units for a mining, preparation and
transportation process
method.
14. As in Claims 1 to 9 the set of sequentially integrated time and motion
algorithms and
calculation subroutines of the "Operating System Calculation Method for
Mining" for the
calculation of CO2 emissions and carbon tax payable per individual mine lease
site owners
and for the overall industry attributable to the numbers of active diesel
powered haul
trucks;
15. As in Claims 1 to 12 the "Operating System Calculation Method for Mining"
being easier to
use than prior statistical mathematical methods of estimating mining and
haulage system
fleet specifications so as to obtain and use an appropriate "oversizing"
factor for selecting
and specifying equipment units for the upstream process flowsheet steps of oil
sand
processing facilities.
16. As in Claim 1 a set of integrated calculation sub-routines of the
"Operating System
Calculation Method for Mining" which enables calculation of CO2 emissions
based upon the
numbers, specifications and load factors of electrical motors including all
electrically
powered equipment or facilities.
17. As in Claims 1 to 14 a master sequence listing for all sequentially
integrated time and motion
algorithms and calculation subroutines of the "Operating System Calculation
Method for
Mining" required to enable an integrated, optimized analysis of equipment
requirements
and CO2 emissions for the comparison of alternate oil sand mining, preparation
and
transportation equipment fleets.
