MSEP enhancements Expanded GSF

Design

200 pits!

Series/AutoP/Starter pit

MSVALP Series/Worst Series/W orst Scheduling

MSEP expanded GSF 200 pits!

No need for multiple GSF files • Easily create GSF using procedure p60110.dat • Support for old GSF files •

Additional items

More TOPO items TOPO1TOPO5 • More Area items AREA1AREA5 • More slope estimate items •

Complex slopes Continues to support current slopes • Soon to allow more slope detail •

MSOPIT–Creating a series of pits Design a series of pits Determine the ultimate pit limit • Develop phases for scheduling •

Multi-Run using BASE option

   SBASE option for selected areas MULTP – limit pushback size    N MULTV – vary value    O    I MULTZ – vary bottom elevation    T AUTOP – pushbacks limited by face angle    PBASE - option with vary prices feature    OStarter pit for AUTOP and MULTP options

BASE option with vary price feature

Scheduling with economic sequential pits

THE “GAP”

Scheduling with economic sequential pits 360 degree mining

AutoP – More realistic phase design Create pits in a preferred direction

Create a series of non-concentric pit shells

Targets high grade material

Honors maximum mining width

Fixes the ‘gap’ issue

AutoP – How it works Mineable area divided into 15  horizontal sectors ○

Each sector evaluated based on mining arc angle range

Economics calculated for each sector

Sector economics weighted by factor (0-10)

Factor could change mining direction

MSVALP enhancements - Scheduling Standard run • • •

Base Constant cutoff Best

Worst • •

No phases or COG optimization used Mines each pit independently top down

Base • •

Schedules pits sequentially ending with each pit No COG optimization used

Best • •

Schedules pits sequentially ending with each pit COG optimization used

SUM files for series options Schedule by period for each pit

PIVSUM creates a pivoted file by pit
