Abstract

Coal mining beneath a river gorge has led to the release into the river of natural gas stored in the underlying rock mass, with associated environmental effects. Geomechanical measurements and numerical modelling studies suggest that an induced fractured zone below the gorge does not effectively connect with the mine caving zone. This is confirmed by geochemical and isotopic analysis of released gas. Predicted gas flow duration, based on measured flow rate and the size of the inferred source reservoir, have been confirmed by subsequent observation.
