Why is the air temperature very hot in deep mines?

2010-8-25  The core of the Earth is around 6000 degrees celcius, about halfway to the core is about 3000, and so on. It should make sense then, that when you go very deep within the crust, where deep mines are located, it gets hotter. The gradient is something like 25 or 30 degrees celcius per kilometer you go within the Earth. Hope this was helpful.

Mining Encyclopedia

2021-2-24  Mining can occur either at Earth's surface in strip mines or open pit mines, or beneath the surface in underground mines. The method used depends on the depth, lateral extent, and economic value of the rock being mined. The deepest underground mine on Earth, which is 2.4 mi (3.8 km) deep, is a South African gold mine.

9.2 The Temperature of Earth’s Interior Physical

Why is the inside of Earth hot? The heat of Earth’s interior comes from two main sources, each contributing about 50% of the heat. One of those is the frictional heat left over from the collisions of large and small particles that created Earth in the first place, plus the subsequent frictional heat of redistribution of material within Earth

BBC Earth How we know what lies at Earth's core

Why does gravity decrease as we go down into the

2021-2-6  $\begingroup$ You could have explained that is not entirely true (distinct from "false") since the earth is like a heavy metal ball with dirt sprinkled on it. Most of the gravity comes from the core. So it makes sense that gravity increases as you dig from the dirt to the core. Once inside the heavier part, however, it decreases, and I think that's the effect the asker was interested in
