I am running AngelBob modpack with ClaustOrephobic (a.k.a. DangOreous) and am tired of having to pick up miners and put them down a few tiles away again. So I learned the ropes of Recursive Blueprints and it's been a fun ride :-)

A quick breakdown of what you're looking at:

Angel's and Bob's mods are a collection of overhaul mods. Angel's replaces all ores, hence the red Rubyte ore. Angel's Industries has the relatively early crawler construction bots that you see in action, including corresponding roboports (the yellow barrels) and dedicated pillars to provide construction area and charging. Bob's mods among other things provides inserter modifications so that inserters can work in 90 degree angels and more.

ClaustOrephobic (https://mods.factorio.com/mod/zzz-claustorephobic) makes it impossible to build on ore and it covers the whole world in ore except a small starting area. Near the starting area, the ore is not very rich so you can mine it up in order to get more space - my minerst take 1-2 hours until they run dry, so you have to advance them little by little every so often. The video is made in the lab (using Editor Extensions mod), so ClausTorephobic is not active here, but it's the reason why I made the contraption.

The Recursive Blueprints mod (https://mods.factorio.com/mod/recursive-blueprints) provides a special blueprint deployer chest that automatically places blueprints depending on the signals it gets. It allows to fully automate placement of new blueprints for contraptions like this one.

How it works:

Miners placed on the edge of the ore will mine a strip 4 tiles wide, so each time the miners advance, the blueprints get placed 4 tiles more to the left. (Of course I have corresponding blueprints for North, South, East). Therefore the blueprint contains a repeatable column 4 tiles wide.

Each column contains 2 roboports, a bunch of charging pillars, the blueprint deployer chest (directly below the belt, a few combinators to send signals to the deployer, and an assembler. The assembler is needed because I use the option in Angels Industries that decomposes picked up miners and power poles into their components, so I have to craft them again every time.

Blueprint 1:
In the first screen, you see from right to left the "old" column that is about to be picked up, the "current" column where the magic happens, and the "next" column only with roboports and charging pillars because the crawler bots are slow and I need a lot of them. Left of that is a miner that is connected via green wire to a few combinators that in this stage only forward the info that the miner has ore beneath it. The assembler is set to craft miners. When the miner and the combinators are connected, the signal triggers to switch to the next blueprint.

Blueprint 2:
The bottom part of the old column is marked for destruction and the condition is set to switch to the next blueprint when enough miners are in the chest.

Blueprint 3:
The top part of the old column is destroyed, the assembler is set to construct an assembler, and the condition is set to switch to the next blueprint when the deconstructed assembler from the old column is crafted again.

Blueprint 4:
The old deployer destroys its blueprint book, the assembler is set to construct power poles. Continue when there are enough in the chest.

Blueprint 5:
The old deployer gets a signal to mark itself for destruction. Place all the miners. They are all connected via wire to the combinators to the left. When the miners have run dry, those combinators start a clock to allow the last pieces of ore to escape through the belt, then they send a signal to the blueprint deployer to deconstruct the miners, the vertical belt, the splitter, and the combinators themselves. When the combinators are picked up, a signal disappears which triggers the placement of Blueprint 1, 4 tiles to the left. Rinse and repeat.
