Indonesian Coal Geochemistry from Sumatra, Kalimantan, Sulawesi, and Papua

Coal samples from Indonesia, a top global thermal coal exporter, are analyzed for quality parameters like sulfur and ash content. The U.S. Geological Survey's World Coal Quality Inventory program collected this data from active mines across major Indonesian islands. It provides a consistent set of coal quality measurements linked to geographic information.

Use Cases

• Classify coal samples by geographic origin using proximate and ultimate analysis data.
• Predict sulfur content from other coal quality parameters to assess environmental impact.
• Map coal quality variations across Sumatra, Kalimantan, Sulawesi, and Papua using linked GIS data.
• Correlate ash content with geological formation data for mine planning.

Strengths

• Data has a high degree of internal consistency for a broad array of coal quality parameters.
• Samples were collected from active mines, ensuring relevance to current operations.
• Data is linked to GIS, enabling spatial analysis.

Limitations

• Specific sample count, row count, and temporal coverage are not provided.
• The description is truncated, so the full list of measured parameters is unknown.
