摘　　要：长期以来,业内一直致力于探索一种既安全又高效的采矿方法,以应对急倾斜破碎薄矿脉的回采难题。根据此类矿体的独特赋存条件,针对原有浅孔留矿采矿法的弊端,进而创新性地采用了长锚索和喷浆预控顶技术,结合下向深孔空场嗣后充填的联合工艺。通过科学合理地布置采场结构参数和爆破参数,实现了矿体的强力开采与高效输出,从而在降低贫损的同时,显著提升了回采效益。这一创新性的实践不仅为同类型矿体的回采提供了宝贵的经验,更在行业内树立了新的标杆,具有重要的借鉴意义。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.
