Feb 15, 2021  To improve the efficiency and reduce costs of cemented-fill mining, we propose a continuous mining and continuous backfilling (CMCB) method based on the coal resources at the Yuxing mine in Inner Mongolia, China, and constructed a complete filling material transportation system. The new technology is suitable for cemented-fill mining of gently inclined coal seams.

Extracting salt from mines

Continuous mining produces smaller lumps of rock using a machine similar to the one used for building tunnels. It bores into the salt extracting lumps that are then crushed into smaller pieces. Both methods ensure that the mine is stable and safe by leaving substantial pillars of salt to support the mine roof.
