or using my tunnel driller,

you can potentially create a tunnel inside the sea floor and seal it off.

 

remember the tunnel walls can be welded with surface panels.

 

then from there, you can dig to any angle.

 

side ways. water is blocked by the tunnel and ground.

 

 

 

 

so i suppose the walls have usages in more shallower surface area.

if to start the drill from there.

or for a different operation not pertaining to mining but construction of an underwater city.

 

 

i guess for mining, underground tunnels will suffice.

 

which would be cost-effective.

 

 

my multi-bucket dig can be used to scoop up excess dirt, if it is a surface-level dig.

but the buckets will need a lid after each scoop, sensors weighing each bucket with content,

when filled up closing a lid.

 

then bring back to surface the samples.

 

better than, 1 scoop at a time.

 

 

 

so how can 3 work together?

walls = maybe underwater city or structure. freedom to construct in ease.

bucket driller = to create base foundation for the structures? most buildings require base to be dugged out to a certain level, cement foundation. also just excavation of surface level mining.

tunnel drill = deeper level mining.

 

ok. that rationalization works i think.

 

 

you can now:

1. surface level mining. (because there is a lid on each scoop, the dirt won't drift away by the water)

2. deep-level mining, with tunnel drills. because tunnel walls can be plated and welded., protected.

3. walls for underground structures, to be built in freely.
