Common parameters used in setting up Transverse Mining Method using Advance Field Offset Dependency Tool

For certain mining methods of underground metal mines, there are generally a list of common sequence that would apply to each mining method. And the common sequence can generally be generated using rules using available attributes that come within the design layers. The below is the list of setups generally required using Field Offset Dependency tool within Micromine Advance for the common mining method- Transverse Mining method.

Offset dependency rules-

• Retreating sequence within the same cross-cut- 
  • Grouping attributes: Level, Drive Number North (Northing)
  • Increasing by using number difference within the same crosscut (Retreat attribute in the example shown below)
    
    
    
    
• Bottom up (or top down) sequence- 
  • Grouping attributes: same cross-cut number, same retreat number 
  • Increasing (or decreasing) by using number difference between Level
    
    
    
    
• Primary Stopes to Secondary stopes sequence- 
  • Grouping attributes: Same level, Same “direction/Zone between E/W or N/S”
  • Both increasing and decreasing for cross-cut numbers
