Abstract

The invention relates to a metal mine transverse drift four-mining one-reserving retreat mining structure and method. The structure comprises a drift roadway close to a mineral vein in the extending direction of the mineral vein and mining regions arranged on the mineral vein at equal intervals. Reserving regions are arranged between adjacent mining regions at intervals. Each mining region is internally provided with primary mining regions located on the two sides, a to-be-mined region and the corresponding reserving regions located between the primary mining regions and the to-be-mined regions. Transverse drifts are arranged on the two sides of each primary mining region, on the two sides of each to-be-mined region and the middle of each reserving region. Working roadways communicated with the transverse drifts on the two sides of the primary mining regions or the two sides of the to-be-mined regions are transversely arranged in the primary mining regions and the to-be-mined regions. The working roadways divide the mineral vein in the mining regions into an outer side front mining region and an inner side blast region. Mining efficiency can be greatly improved, mining safety is greatly improved, and the yield of high-quality ore can be increased.

Description

technical field [0001] This application relates to a mining method, in particular to a mining structure and method for metal mines, which adopts vein-piercing four-way mining and leaves one for non-piercing, and is combined with hydraulic fully mechanized mining technology. Background technique [0002] The mining technology of metal mines mainly stays in the layered mining and cemented filling technology of "using vein-piercing lanes to mine one and leave one". In this mining technology, the vein-piercing lanes are opened at intervals of 15 meters, and the blasting mining is separated in each vein-piercing lane In theory, only half of the layered ore body can be mined and half can be left, which leads to imbalance of mining and imbalance of mining and filling in production. [0003] At the same time, metal mines use vein-piercing fan-shaped blasting blasting and deep-hole blasting for blasting. This blasting method requires blastholes to be arranged at an elevation angle of...
