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
