Abstract:Safe and efficient deep mining is an urgent problem facing the development of metal mineral resources in China. In recent years, remarkable progress has been made in China’s mining technology. However, owing to a relatively late start, there remains a certain gap compared to mining-developed countries. Through a comprehensive investigation of the current state of deep thick massive ore body mining technologies at home and abroad, this paper summarizes the characteristics of deep thick massive ore body mining in China. It introduces international case studies of deep thick massive ore body mining, and elaborates in detail on China’s practical experiences with backfill mining of these deposits. The aim is to innovate and establish a new mining model for mines of ultra-deep (exceeding 1000 meters) and 10 million tonnes per year production rate, prioritizing safety and green, low-carbon requirements, thereby providing guidance and reference for mines in China currently confronting the challenges of deep thick massive ore body extraction.
