摘要
Abstract
For a long time,the industry has been committed to exploring a safe and efficient mining method to deal with the difficult problem of mining thin veins broken by sharp incline.In view of the unique occurrence conditions of this kind of ore body,we have innovatively adopted the combined technology of long anchor cable and shotcrete pre-control roof,combined with the down-deep hole open stope and subsequent filling,aiming at the shortcomings of the original shallow hole stope mining method.Through scientific and reasonable arrangement of stope structural parameters and blasting parameters,we achieve strong mining and efficient output of the ore body,thus maintaining low loss and depletion at the same time,significantly improving the recovery efficiency.This innovative practice not only provides valuable experience for the mining of the same type of ore body,but also sets up a new benchmark in the industry and has important reference significance.关键词
