The tailing pond in Jiaojia Gold Mine has insufficient capacity,and the fine-grained tailings can not be fully utilized as backfill into goafs.In order to alleviate tailing discharge pressure,the pattern that the fine-grained tailings are backfilled and the coarse-grained tailings are processed and sold have been implemented.In order to add new goafs,a production model of mining low-grade ore in shallow areas of underground mines,at the same time increasing the amount of metal recovered.The practice shows that waste rock utilization＋low-grade resource comprehensive utilization＋tailings recycling collaborative technology production process has realized the construction of a waste-free mine in Jiaojia Gold Mine,and also has provided valuable experience for similar mines to achieve a waste-free mine,which is of reference significance.
