catalyst 8pm abc tonight, page-4

Well presented story to the uninitiated. UCG seemed to have a more positive spin than CSG which was pleasing.
One question that was posed which someone may be able to clarify is theat UCG is like long wall mining only underground, so will it have the same subsidence issues as long wall mining? It's something I hadn't thought about but I certainly am not an expert in the technology, only a hopefull believer.
