Can some kind soul shed light on why it is necessary to pump the main shaft with "hundreds of tons of concrete" to permanently seal it off? It just seems totally unnecessary to me and incredibly short-sighted in view of the possibility that at some future time we may need to access that resource again (maybe one day a process will be devised whereby the energy in coal can be cleanly released for instance). Why burn our bridges in this way?
