What is Humidity Test for Coal Mine Drainage about?

This document summarizes a study that used a Humidity Column Test (HCT) to predict mine drainage quality from two rock samples from a coal mine in Indonesia. The HCT subjected the samples to repeated wet and dry cycles over 56 days to simulate weathering. Water quality measurements found that sample PE weathered faster and had a lower pH, classifying it as having a high potential to generate acid mine drainage. Sample Q10 weathered slower and had a higher pH, classifying it as having intermediate potential
