Modeling the Project Coal Seams

This document presents a comprehensive modeling analysis of the #6 coal seam, highlighting key factors that affect mining operations. It discusses the consistency of the Brereton limestone's thickness and strength, revealing its robust nature while also pointing out challenges posed to longwall mining. The investigation examines changes in the #6 coal thickness, identifies potential minable and unminable areas, and looks into the presence of Energy Shale. Additionally, it reviews fault distance implications and the geological patterns that might impact extraction strategies.

Presentation Transcript

  1. Modeling the Project Coal Seams

  2. The #6 Coal • Things that did not change • Thickness of Brererton Limestone 20 ft • Strength of Brererton Limestone • Massive almost indestructible roof • Good news for bolting • Bad news for longwall • Underclay 3 ft • Strength of underclay 1000 psi • Compared to coal strength 2500 psi almost guarantees that floor strength will govern pillar design

  3. #6 Coal Things that Changed • Thickness of #6 coal • Likely guarantees both minable and unminable areas • Presence of Energy Shale • Sulfur content of #6

  4. Finding Fault Distance = 200 ft.

  5. Which Way Did It Go? Lines of Drill holes

  6. Do You See Anything? Distance 2,600

  7. Implication

  8. Might Be Where I Guessed Distance 6,600 feet

  9. Another Line

  10. I May See the Expected Pattern

  11. Searching for Channels
