pithead n the entrance to a coal mine Usage(s) At every working pithead in the United Kingdom last week smut-faced coal miners voted in favor of a nation-wide strike, 409,351 to 29,215. British coal production was off about 55 million tons since 1937; in many old mines, the coal face was three miles from pithead. At the pithead, a reporter shouted the news to a local man climbing out of his car.
