Summary: | The invention discloses a tailing pond dry-type stoping method which comprises a stoping area I, a stoping area II, a stoping area III and a stoping area for final stoping, and sand taking strips, sand taking shortcuts, in-pond transportation roads and sand mining pit water guide and drainage pits are used in blocks. The following technical scheme is adopted for taking sand and selling the sand into the pond: the tailings pond is divided into regions, blocks and strips, and the sand is taken from each region in a layered and strip-by-strip manner. In the recovery process, the beach face trend of the recovery process is strictly controlled, and water guide and drainage ditches are arranged in an area junction area for flood drainage so as to reduce flood drainage pressure; layered mining is carried out, and the slope ratio of a stoping slope is controlled in the mining process so as to improve the safety and stability of the stoping slope; meanwhile, manual stoping is carried out on the stoping protection area |
