Coal Pore Structure and Methane Desorption Efficiency Data

184.0 KB of data from a study linking coal metamorphism to pore structure and methane desorption. Authored by Xiaomin Liang and last updated on 2026-05-14, the dataset likely contains quantitative measurements of micropore, mesopore, and macropore characteristics across different coal ranks. The results show micropores dominate specific surface area (>96.5%), while macropores contribute most to total pore volume (>45.2%).

Use Cases

• Modeling methane desorption efficiency based on micropore spatial distribution types (attached, networked, isolated).
• Correlating coal rank (lignite, coking coal, anthracite) with pore development trends.
• Analyzing the relationship between pore connectivity and gas transport efficiency for CBM extraction optimization.

Strengths

• Quantitative findings are specific, such as micropores contributing >96.5% of specific surface area.
• The study provides a novel mechanistic link between pore topology and desorption behavior.
• Data is shared under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small in scale at 184.0 KB, indicating limited scope.
