Deleted Journal, Journal Year: 2024, Volume and Issue: 1(1), P. 27 - 39

Published: March 1, 2024

To reduce or eliminate environmental damage during mining processes, green practices have emerged as a focal point in China's metal research. Cemented paste backfill technology plays pivotal role promoting within the industry. The allows safely backfilling of surface tailings into underground airspaces, effectively addressing challenges associated with storage and goaves. In this paper, we introduce rheology theory system, which forms theoretical backbone cemented backfill. We delve key technologies such thickening, mixing, transportation, use economical, low-carbon materials. Additionally, analyze macro micromechanical properties, in-situ performance monitoring, barricade construction, intelligent control, numerical simulations process. establish several demonstration projects, both domestic international, that utilize to foster greener practices. is widely used all over world. It has evolved from its initial stages being recognized an advanced application by various ministries commissions. Ultimately, propose future research directions for context eco-friendly mining. These perspectives encompass theory, technology, equipment, mode, can strongly contribute sustainability industry China.
