Stability Evaluation Of Alternative Designs Of Drift-And-Fill Stoping In Zhaoyuan Gold Mine, P. R. China

Mining economics is such that too conservative in safety will result in a considerable penalty in mining cost. However, initial planning and design of a mining project often must be done without complete information. The assurance of economical and safe mining is thus difficult. This study is focused on the improvement of the mine design associated with Zhaoyuan Gold Mine in P.R. China as more information becomes available. Attention is given to the selection of backfill structures. Based on a proposed practical finite element model, a design, which is believed to be not only reliable but also cost-effective, is recommended for further mining operations in this mine.
