A kind of mining method of gently inclined layered extremely thin ore body in metal ore

Abstract

The invention discloses a mining method of a gently inclined layered extremely thin ore body in a metal ore in the technical field of mining, A: stope division; B: mining standard engineering; C: cutting engineering; D: ventilation; E: ore transportation Move; F: Ground pressure management: Compared with the traditional mining method, the advantage of this mining method is that there is no need to set up a traditional ventilation patio. The traditional ventilation patio has a large ventilation resistance due to its small cross-section, and this ventilation method is directly provided by the transport roadway in the next stage. After entering the working face through multiple funnels, the polluted air is discharged from the connecting road to the transportation roadway in the upper stage, with small ventilation resistance, large air volume and good ventilation effect. In addition, it also saves the amount of excavation work in the raised shaft and reduces the mining cost; secondly, the backward ore falling adopts violent and mechanical handling, and the double working face has a large amount of ore and high work efficiency.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a mining method for a gently inclined layered extremely thin ore body in a metal ore. Background technique [0002] When the metal mine is in progress, the traditional ventilation patio has a small section and large ventilation resistance, which leads to poor ventilation effect, and the traditional patio has a large amount of mining engineering, which increases a lot of mining costs and mining time. At the same time, the traditional mining method works more efficiently. Therefore, we propose a mining method of gently inclined layered ultra-thin ore body in metal ore. Contents of the invention [0003] The object of the present invention is to provide a kind of mining method of the gently inclined layered extremely thin ore body of metal ore, to solve the problem that proposes in the above-mentioned background technology. [0004] In order to achieve the above object, the presen...
