In-vein filling mining method

Abstract

Disclosed is an in-vein filling mining method. According to the in-vein filling mining method, stoping and filling are carried out in V-shaped ore chambers formed in cutting grooves of all layers, andan out-of-vein filling mining method and a traditional in-vein filling mining method are combined, so that in-vein gate ways have the transporting and filling functions, the ventilation function is achieved during in-vein cutting, simultaneous stoping of the multiple ore chambers can further be achieved, and thus the productivity problem of end retreating mining is solved; meanwhile, when the V-shaped ore chambers are stoped, the productivity of the multiple ore chambers can be released simultaneously; finally, inverted-V-shaped intervening pillars are recovered so that interval layered stoping can be conducted, namely simultaneous stoping is conducted from the lowest layer of a panel according to of the first layer, the third layer, the fifth layer..., and finally the second layer, the fourth layer and sixth layer...are recovered; and therefore, the current situation that through a traditional end retreating mining method, the productivity of the panel is excessively low is changed greatly, and the ore recovery rate is further increased.

Description

technical field [0001] The invention belongs to the technical field of mining, and in particular relates to an intravein filling mining method. Background technique [0002] At present, the commonly used filling mining methods include the filling mining method outside the vein and the filling mining method inside the vein. Due to the high development ratio of 10,000 tons (about 10,000 tons / 140 meters) in the mining method of filling outside the vein, the mining cost remains high, while the traditional filling mining method in the vein withdraws mining from the end, and builds a retaining wall in the flat road in the vein, and The production capacity is too low due to insufficient mines. [0003] Chinese patent (publication number: CN103061767B) discloses a kind of downward horizontal layered dry filling mining method, this method uses the mining form of downward horizontal layering, has adopted the method for filling with mining, although improves to a certain extent The m...

Problems solved by technology

Due to the high development ratio of 10,000 tons (about 10,000 tons / 140 meters) in the mining method of filling outside the vein, the mining cost remains high, while the traditional filling mining method in the vein withdraws mining from the end, and builds a retaining wall in the flat road in the vein, and Production capacity is too low due to insufficient mines

[0003] Chinese patent (publication number: CN103061767B) discloses a kind of downward horizontal layered dry filling mining method, this method uses the mining form of downward horizontal layering, has adopted the method for filling with mining, although improves to a certain extent It improves the mining efficiency, but it cannot meet the demand for simultaneous mining of layered veins. Therefore, it is necessary to provide a filling mining method that can buy groups and multi-layered veins for mining.
