Abstract

The embodiment of the invention discloses a mining preparation system and a mining method for steeply inclined phosphorite. The mining preparation system comprises a top plate and a bottom plate, wherein a first stoping surface and a second stoping surface are arranged between the top plate and the bottom plate, an ore bed is arranged between the first stoping surface and the second stoping surface, a first air return roadway and a first transportation roadway are formed in the first stoping surface, a second air return roadway and a second transportation roadway are formed in the second stoping surface, mining and loading machines and conveyors are respectively installed on the first stoping surface and the second stoping surface, both the first transportation roadway and the second transportation roadway are arranged near the bottom plate, and both the first air return roadway and the second air return roadway are arranged near the top plate. According to the mining preparation system and the mining method for the steeply inclined phosphorite, the layout of the mining preparation system is simple, continuous mechanized production can be realized, the recovery rate is greatly increased, depletion is greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mining of ore bodies, and in particular to a mining system and mining method of steeply inclined phosphate rock. Background technique [0002] With the transfer of phosphate rock from above ground to underground and from shallow to deep mining, the recovery rate will drop sharply, the dilution will rise sharply, the production efficiency will drop sharply, and the safety production conditions will continue to deteriorate. Therefore, there is an urgent need for a mining standard system and mining method suitable for steeply inclined phosphate rocks, especially a mining standard system and mining method for phosphate rocks with large dip angles and thick seams. Contents of the invention [0003] Therefore, the embodiment of the present invention provides a steeply inclined phosphate rock mining system and mining method to solve the problem in the prior art that the recovery rate ...
