Ok, looking for the best ways to get heat out of my mining room...

8 x 10 room with 9ft ceilings, single window, single inside door. Generating a lot of heat.

I don't know anything about thermal stuff. Would it be best to:

1. Use a vent hood like apparatus with fan to get heat into the attic?

2. Use an attic fan for the same affect?

3. Put a fan or air conditioner in window for fresh/cool air?
