If I can figure out how the forum runs, I'll go out and make you a video of me making a "beehive" fire; though I've never called it that. I've (tong) lifted the coked "shell", if you will, off the fire before just to try it.
Re: your picture above , yes, that's about what it looks like with the exception that ideally it would have more fuel.
The "blast" can be at any point around the fire. Yep, its hot. If you decide to walk across the street and heap green coal on the roaring forge as a fire containment as mentioned above - great! That's an excellent way to get this "hive" called fire. Come back (in a reasonable amount of time ), give the fire a steady breath of air, & poke a horizontal hole wherever you want to work from. This is hard to explain now that I'm the one explaining & I am just finishing up my first year of fire management training.
As I need fuel , I just chip away at the shell, maintaining the single opening to work in. My setup is similar to your setup in the picture. I use bituminous smithing coal & I agree with Reynolds on most points, but I don't have to wear gloves. I also just listen to when the fire is ready; then I poke my work opening.
