Field experiments reveal improved waste dump capacity in coal mining, suggesting modified dumping method and compaction techniques enhance stability.

Waste dump capacity increased from 5,444,097 BCM to 7,249,037 BCM after compaction modifications.
Reductions in dumping height and increased compaction were statistically proven to improve material strength.
Geotechnical simulation confirmed a stable slope angle increase from 6° to 7.5° while maintaining a Factor of Safety of 1.32.
Regression analysis indicated a strong correlation between compaction density and the strength of waste dump material.

Wicaksono et al. (2025) studied this question.
