Most deep mines are very warm. The two big sources of heat in mines are the rock (warmed by heat from deeper), which heats up the air, and autocompression.
Groundwater, etc, can affect the temp of shallow mines, but below a few hundred feet, it's pretty much that deeper = warmer. There are very few mines "near" magma sources, though some areas of the crust are warmer than others. Also, nearby water flows can affect the temperature. Deep mines are almost uniformly warm to hot, though.
The second source of heat is the compression of the air sent into the mines. Since the mine is so deep, the column of air is heavier, increasing the air pressure inside the mine. This increases the temperature of the air as well.
Finally, almost all of the energy from drilling, blasting, machinery, etc, ends up in the rock, warming it.
how many countries were involved in chilean mine rescue operation?
augest 5
Copper
nothing
The 2010 Chilean mine collapse was caused by a cave-in at the San Jose copper-gold mine. The collapse trapped 33 miners underground, leading to a dramatic rescue operation that garnered worldwide attention.
On August 5, 2010
With food and supplies from above
In the San Jose mine in Chile
they went in. roof fell. trapped.
ASTON IS SO CUTE but he is mine mine mine so stay away lol
Copper and Gold
People made holes in the soil and rocks and pushed the food into it.
