Re: sources for the math.
https://en.wikipedia.org/wiki/Rotational_energy
The earth has 2.14 * 10^29 joules of kinetic energy in its rotation.
Reducing that by 0.5 seconds requires:
Fraction of total = 0.5 seconds per day / 86400 seconds per day = 0.00000578703
2.14 * 10^29 joules * 0.00000578703 = 1.24 * 10^24 joules.
1 joule = 1 watt second, so...
1.24 * 10^24 J = 344,007,202 terawatt hours.
Humans produce about 11,037 gigawatt hours of electricity per year, so:
344,007,202 TWh / 11.037 TWh / 1 year = 31,168,542 years
Thank you for asking me to double check my math, I forgot to convert GWh to TWh the first time.
It would take over 31 million years, not 40,000 - I was wrong.

I mean, I did the math to show that mining causing any significant changes in the earth's orbit or rotation is complete nonsense.
It would take millions of years of effort, with all human energy going to this singular purpose, to make even a miniscule change.
Natural processes will dwarf anything humans do to alter the earth's orbit many times over.
If you believe in this mathematically impossible nonsense, there's nothing more to say. I've shown you the numbers. Humans can't alter these things. We just don't have the energy.

I'm not sure you're understanding me.
Yes, mining effects the rotation of earth.
It will change it by a few nanoseconds. Not enough to impact the environment.
It's not physically possible for us to do more than that. Doing so would require millions of years worth of electricity. See the math above.
