Pore Structure Analysis of Three Coals with Different Metamorphism Degrees

Xiaomin Liang's dataset on figshare quantitatively investigates the pore structure of three coals with different degrees of metamorphism. The data reveals spatial distribution forms of micropores and their influence on methane desorption efficiency. The dataset was last updated on May 14, 2026.

Use Cases

• Modeling methane desorption efficiency based on micropore spatial distribution types.
• Correlating coal metamorphism degree with pore volume and specific surface area metrics.
• Optimizing gas recovery strategies by identifying coal types with attached versus isolated micropores.
• Assessing geological hazards in coal mining based on pore connectivity trends.

Strengths

• Quantitatively analyzes pore structure across three distinct coal types (lignite, coking coal, anthracite).
• Provides specific surface area and pore volume percentages for micropores (>96.5%) and macropores (>45.2%).
• Links pore topology (attached, networked, isolated micropores) directly to desorption behavior.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 5.5 KB, indicating limited scope.
