The Mine Drainage Quality Prediction of Surface Coal Mine Rock Samples with Humidity Column Test

Abstract

A kinetic test, namely huminity column test (HCT) was conducted in the laboratory to predict the mine drainage quality of two samples from a coal mine in Kalimantan, Indonesia, Futhermore, the study calculated weathering rate of these samples per cycle and identitified the parameers controlling the weathering process. The samples came from fresh rock of the active pit (PE) and disposal area (Q10)-A static test was conducted and aimed these samples and showed the classification result of the samples
