So a rather peculiar drawing I know but I wanted to save time mixing it with MS paint instead full CAD drawing.

 

So what you see in that is a mechanism that will level the whatever protruding mountains or rocks or objects.

 

and the machine carrying it should be adaptive to the terrains so why a pecular angle changing wheeler.

 

with more ridgid rods/pistons that in combination with induction motors and replaceable coonsumable attachments on contact with the rocks, which will wear out over time,

 

it will level the protruding surfaces.

 

And once that is leveled, let me get to the next part.

 

So when any protruding surfaces are leveled,

then another machine, that forms this circular 'road' downwards spiral,

can be used to dig downwards.

Technically, more down to earth (vertically) version of my machine,

to keep balance, can rotate the horizontal drill angularly, to achieve the same effect,

but i'm sure there are machines for this downwards spiral anyway.

 

So once that is dugged in this way, and the spiral road is completed.

My horizontal machine can be used again to create larger dig.

Until there is only a giant cubic hole.

 

So where I am getting at here is:

1. Size that can be scaled as in the machine and its components.

2. Components that can be replaced by casting and fewer foreign materials required.

3. Therefore aiming at extremely speedy mining. Something that devours an area fast without need for explosives.

 

The back wheels can also vertically go up and down, in order to change the angles of the horizontal drill, to befit the whatever protruding surface drill angles. Much like my laptop stand right here I just bought, has two levels of adjustible angles. XD

 

Adding one more angle lifting point.. If required.

Obviously the shapes can be optimized,

but following my principles of size, weight, castable, replaceable components, some modular on the wearable. it should be able to level out the areas very fast.

 

Anyway, got things to do today.
busy. appointment with the family doctor...
