Fault Water-Resisting Coal Pillar Stress Analysis Data

24.2 KB of source data for figures comparing deep-beam analytical methods in coal pillar design. The dataset supports validation of a layered decomposition method against classical elasticity solutions and FLAC3D simulations. It includes results from an engineering case study in a deep coal mine in northern Anhui Province.

Use Cases

• Compare mid-span normal stress predictions from layered decomposition and classical elasticity methods for h/L ratios of 0.3–1.0.
• Validate analytical stress solutions against FLAC3D numerical simulations for deep-beam models.
• Analyze the predicted pillar width from the case study against empirical design guidelines after applying a safety factor.
• Assess the relative error in stress calculations for different layer discretizations (e.g., 10, 16, 20 layers) in the proposed method.

Strengths

• Data is validated against FLAC3D numerical simulations for accuracy.
• Includes results from a specific engineering case in a deep coal mine in northern Anhui Province.
• Quantifies relative errors (6.0%–9.9%) for the proposed method's stress predictions.

Limitations

• Dataset is very small at 24.2 KB, indicating limited scope and likely few data points.
• Specific row count, column structure, and sample data are unavailable, hindering assessment of completeness.
• Focus is narrow, limited to the specific mechanical analysis of fault water-resisting coal pillars.
