I'm a great big fan of the TA Miners mod.

Unfortunately, even though the TA Miners "extractors" indeed appear in the Planner, the Planner insists on clumping them together, ignoring the "reach" of those extractors, causing unnecessary overlap of extraction areas.

(Case in point: A uranium patch that can be covered by a single "Crust Extractor", the Planner insists on using 4 extractors to cover the patch.)

If it is possible, please have the Planner inspect the "reach" of the TA Miners' extractors, so that when planning, no unnecessary overlap will happen.

(A single extractor on its own is capable of overwhelming multiple belts anyways; I always have to feed the extractor's output directly into a storehouse -- from the [Warehousing Mod] -- to be able to fully utilize their extraction power.)

Try using the Sparse layout with them. I've released a fix for the spacing.
You could also try setting up a custom blueprint for the Blueprint layout but I need to add support for mining drills inserting into containers and inserters/loaders extracting the items.

Released an update to support container+loader combos in Blueprint layout.

Try setting up a Blueprint layout with a TA Miner now. Set the grid size up to the desired reach of the mining drill area.
Showing an idea how a big mining drill can insert into a container and contents extracted with a loader

Cool! I'll update and test it out!
