Abstract

The invention discloses a novel dry-type stoping method for tailings in a tailing pond. The tailing pond is investigated, gravels are used for laying of temporary gravel roads (1) from tailing pond dam bodies to a tailing pond drainage well (2), and the temporary gravel roads (1) are taken as temporary construction roads; temporary drainage ditches are dug on two sides of each road by means of mechanical digging equipment; to-be-stoped tailings under tailing pond beaches (3) on two sides of each temporary gravel road (1) are dug in each area by means of a digging machine after water accumulated in the tailing pond is drained off; after stoping in one area is finished, stoping is performed in another area until the tailings in all the areas on the layer are stoped; tailings on two sides of each temporary gravel road on a lower layer are dug in each area until tailings in the tailing pond are all exploited. The stoping work of the tailings in the tailing pond is finished on a large scale quickly and efficiently, the stoping efficiency of the tailings in the tailing pond is improved, the stoping cost is reduced, and the stoping time is saved.

Description

technical field [0001] The invention belongs to the technical field of tailings mining, and in particular relates to a tailings dry mining method, which is especially suitable for medium and small tailings reservoirs with small tailings beach foundation bearing capacity, short required construction period and small tailings stockpiles. Small tailings pool tailings recovery project. Background technique [0002] At present, in the tailings mining of tailings ponds in my country, there are mainly three methods of tailings mining: water mining, ship mining and dry mining. [0003] Water mining is pressurized by means of a water pump, and the high-speed water flow generated by the high-pressure water gun and the gravity of the tailings itself will impact and collapse the tailings to break and separate the tailings. It is characterized by large production capacity, low cost, and screening and debris removal. The equipment is simple, especially suitable for depositing tailings wi...
