Solution Engineering — Mining Conditions Visualization for Legal Evidence

Challenge

Two underground coal mines — Shay No. 1 Mine in Carlinville, Illinois and Deer Run Mine near Hillsboro, Illinois — had been operating intermittently, producing bituminous coal. At critical junctures, both mines faced significant operational and geological challenges. In the case of Shay No. 1, ongoing issues with coal quality and profitability contributed to operational idling, and by 2020 the site was documented as idle or mothballed.

In the Deer Run Mine case, after underground combustion events and extended idleness, disagreements arose between the coal operator and the property owner over lease obligations — centered on whether the mines were still “minable and merchantable.” The mines’ complex geological conditions, including underground fires, made traditional documentation insufficient for demonstrating unworkability.

The mining company engaged Solution Engineering to create 3D walkthrough visualizations of the subsurface conditions to convincingly demonstrate, in technical and visual terms, that the coal seams were sub-standard and unworkable — evidence intended for a bench trial.

Insight

Highly technical narrative evidence — especially in legal settings — must do more than show reality. It must translate complexity into convincing, adjudicative clarity. Judges and legal decision-makers are not trained geologists; their decisions hinge on comprehension, trust, and clear visual data, not just dry reports.
This project required not only accurate mapping and geological fidelity but also strategic visual storytelling: turning ambiguous subsurface conditions into a narrative that supported the legal standard of “not minable and merchantable.”

Idea / Platform

Rather than supply static reports or disconnected renderings, we created immersive 3D walkthroughs of key hazardous sections of Shay and Deer Run, documenting structural instability, geological degradation, and the consequences of underground fire events.
This strategy treated the mines as narrative environments rather than as data points:

• Emphasize spatial understanding — not just text, but virtual traversal.
• Highlight cause-and-effect — what conditions prevented safe and profitable mining operations.
• Provide a guided narrative experience that judges and legal decision-makers could interpret in real time.

Execution

• 3D Modeling: Generated detailed digital models of the underground tunnels and chambers based on survey data, bore logs, and field observations.
• Narrative Walkthrough Development: Built a sequenced visual exploration that guided the viewer from surface entry through deteriorated sections, focusing on areas of collapse, fire impact, and coal depletion.
• Visual Annotations: Included clear visual callouts and narrated overlays explaining the significance of each condition in lay terms.
• Integration with Legal Presentation: Worked with attorneys to embed the walkthrough into legal exhibits, ensuring compatibility with courtroom technology and bench trial formats

Impact

• The 3D narrative walkthroughs served as critical evidence in a bench trial, allowing the judge to see and understand conditions that were otherwise abstract or disputed on paper.
• The judge’s acceptance of the visualization evidence helped establish that the coal seams were no longer minable or merchantable — contributing to the legal resolution in favor of the mining operator’s position.
• This case exemplified how strategic visual storytelling can influence high-stakes decisions where traditional documentation falls short.
