I bet he doesn't use electric tools like that either. Everything must be certified intrinsically safe before it can be taken underground, at least in Australia.
Used to work in a mine and had to calibrate all of the gas sensor stations as well as perform ventilation surveys on a weekly basis. This ensured that every working area had ample air flow for all of the equipment that was running and that no areas were exposed to harmful levels of toxic gases. Everyone wore gas detectors as well which would alert if they sensed explosive gases.
Yes, most electric tools will spark somewhere. They need to be specifically designed for explosive environments. I used to do metal fabrication in aircraft fuel tanks sometimes, and we had to use air drills and brass punches to avoid making any sparks.
