I hate to rain on your parade, but I think you were just lucky in your timing. When the coal bed is reaching that critical point where the gas/air mix is close to ignition, a matter of a minute can make the difference between gentle whoosh and BANG. I recommend (just call me Mr.Know-It-All) that you NOT close the ash door before opening the load door when going through that revival process. Just closing the ash door can sometimes make the bang by suddenly making the mixture richer in coal gas and leaner in air. With the ash door still wide open, SLOWLY open the load door, then SLOWLY close it. Closing it too fast can also trigger a bang. Once you get flames that sustain themselves after you close the load door, then close the ash door but still with the spin draft wide open. Let 'er rip for awhile like that, until stove temp gets up to a reasonable number, then close the spin draft to a reasonable level.
That works well for me when loading new coal, and I'm sure it would work for reviving your fire. However, it's not very practical, because reloading a hot stove requires the door-open-close process for only a few minutes, whereas reviving after a long idle would require you to play with the doors for much, much longer. Sorry, I don't have a practical solution for your case.
