A kind of quasi-mining system and mining method of inclined phosphate rock

Abstract

The embodiments of the invention disclose an accurate mining system and mining method of inclined phosphate ore. The accurate mining system includes a stoping face and a mining area roadway, wherein the stoping face includes a transportation roadway, a return air roadway, an intermediate roadway and a cutting roadway; the mining area roadway includes a return air dip, a transportation dip and a connection roadway; the transportation roadway, the return air roadway and the intermediate roadway are arranged in parallel along the strike of an ore bed, and the intermediate roadway is arranged between the transportation roadway and the return air roadway; the transportation roadway is arranged at the lower end, near the floor, in a seam; the return air roadway is arranged at the upper end, nearthe floor, in the seam; the cutting roadway communicates with the transportation roadway, the return air roadway and the intermediate roadway; the return air dip communicates with the return air roadway and the intermediate roadway; the transportation dip communicates with the transportation roadway; the connection roadway communicates with the return air dip and the transportation dip, and the connection roadway is provided with a substation. The accurate mining system of the inclined phosphate ore provided by the embodiment is simple, continuous mechanized production is realized, the stoping rate is greatly improved, the dilution 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 for inclined phosphate rock. Background technique [0002] As the phosphate rock is transferred from above ground to underground, and from shallow to deep mining, affected by the increase of mine pressure, the ore seam and the roof of the mine seam become broken and soft. If the traditional room-and-pillar method is adopted, the recovery rate will drop sharply, diluting There is a sharp increase in production efficiency, a sharp decline in production efficiency, continuous deterioration of safety production conditions, and continuous decline in mine economic benefits. Therefore, there is an urgent need for a mining system and mining method suitable for inclined phosphate rock. Contents of the invention [0003] For this reason, the embodiment of the present invention provides a quasi-mining system and ...
