Tongchuan Mining Bureau has 13 pairs of production mines, design capacity of 8.22 million tons. Carboniferous Permian and Jurassic coal fields were exploited separately, and in 1982, a total of 6,776,994 tons of raw coal were produced. Among them, there are 10 pairs of Limeji Permian coalfields, with a designed capacity of 5.37 million tons, three pairs of mines in the Jurassic coalfield and a design capacity of 2.85 million tons. In 1982, they produced 5,097,000 tons of raw coal and 1,679,000 tons of raw coal respectively. Carboniferous Permian coalfield has two main recoverable layer.
