Survey and mining method research of residual ore resources in near the goaf

Due to the influence of early mining techniques, many mines in China still have a large number of irregular high-grade ore pillars near the goaf. These residual mineral resources are often difficult to recycle due to the influence of mining technology conditions. Exploring the occurrence of these residual ore resources and studying reasonable recovery methods and approaches will have significant social value and significance. This study investigates the residual ore resources in the near the goaf, analyzes the difficulties faced in mining mineral resources, proposes reasonable mining processes and ideas, achieves safe and efficient recovery of mineral resources, extends the service life of the mine, and increases the economic benefits and social value of the enterprise.
