The Recent Progress China Has Made in the Backfill Mining Method, Part II: The Composition and Typical Examples of Backfill Systems

The backfill mining method is a widely used mining method in the major mines of China, which can maximize the recovery of mineral resources and protect the environment. Currently, major mines in China are starting to build backfill systems to apply the backfill mining method, therefore, Part II reviews the progress China has made on creating backfill systems, of which the main contents include: (1) Composition of the backfill system common in Chinese mines; (2) Typical examples of the backfill system in China. Finally, Part II serves as a guide to begin a conversation, and to encourage experts and scholars to engage in the research of this field.
