Underground mining in China is reaching great depths. While in 2004, the mines at 1000 m depth were only 8, in 2015, these were more than 60. Thus, deep mining kept increasing and coal resources at depths greater than 1000 m account at present for 53% of the total available resources. Coal mining extends to depth at a rate of 10–25 m per year.
