PRACTICE OF SHORT-HOLE SHRINKAGE STOPING WITH FLAT-BOTTOM STRUCTURE IN DERBUR LEAD-ZINC MINE

Short-hole shrinkage stoping is a common mining method adopted in metal mines in China. Based on the practice of this method in Derbur lead-zinc mine, Inner Mongolia, with analysis on the problems of the traditional short-hole shrinkage mining in production, this paper improves the bottom structure and puts forward a short-hole shrinkage method with non-pillar flat-bottom structured rock loader. This method has been successfully applied in production with satisfying effect. Such an idea and practice is significant for similar mines as reference.
