The dust would hang in the air and everyone would breath it in.
Turning up your miner's lamp to full-brightness you can see glinting
tiny particles in the air - highly likely to be silicate.  Just a test
little bit of drilling before everyone heading to surface.  Not even
"production-level" amounts of drilling.
Absolutely cannot be.
Water flood (actually not a lot of water) to get a slurry.
Nothing glinting in the air by same test of miner's lamp at
full-brightness shining along the level so bright in the beam and no
reflecting-back light (lost a hundred metres and more away).
Completely effective in that regard.
But then yes how to get the adherent slurry out of the drilled
sockets...

The brief but important part of my post was how to connect flexible rubber or vinyl tubing to a drink bottle cap. In the USA threaded electric lamp tubing has the non-tapered "IPS, Iron Pipe Straight" version of 1/8" pipe thread, and brass lock nuts for lamps could reinforce the pipe thread joint into the bottle cap.

The flexible tubing connection could be a barbed spigot, compression with a plastic sleeve, or a push to disconnect fitting. Flare might even work, I haven't tried it on vinyl tubing.
IPS female fits but usually requires a rubber washer to seal on NPT (pipe) male. Sink spray and shower head hoses may use it. The high pressure hydraulic equivalent is named "swivel" and seals with a metal cone.
