Abstract
The steel industry in Japan has expanded year by year and the enormous amount of coking coal for iron industry is imported from USA, USSR, Canada, Australia and Poland etc. Then it is necessary to know the fundamental geologic data about coking-coal produced countries.
The outline and characteristic data of geology of many coal fields are described in this paper. The future exploration of coal resources will be expected in east part of Eurasia Continent, in the intercountry part of Australia and in the west part of Canada.
