According to the Researches on Coal Development Strategies in China (1991 ~ 2020),the production scale of coal in China will increase to 2100 Mt in the year 2020 and the district layout of coal development and production will be diverted from the east to the central-west step by step. In addit1on, the multi-ply runnning struc ture-mines of the nation,the local and the village and town combined with produc tion scales of the large, the middle,and the small-will be kept.
