Assessment of status and extent of fire in abandoned coalmines - a case study

摘要

The problem of fire in abandoned mines is a global challenge to all coal producing countries. The main and immediate concern is to save the vital surface structures like railway lines/roads, bridges, rivers/stream, overhead construction from such fires as well as protecting adjacent underground property of the mine either by isolating or digging out permanently. But the difficulties are being faced, in both the cases of isolation of such fires, due to lack of knowledge of exact location of fire in unapproachable mine as the surface evidence of fires may not be related by straight line paths to the source of combustion.
