Abstract

The invention discloses a mechanical continuous mining method for a gently inclined thin ore body. Based on the principle of lengthening the slope distance to reduce the angle, ore blocks are arranged in an inclined way, so that an angle smaller than the original inclination angle can be formed between a working plane and the horizontal plane, thus creating an operating space for a drill jumbo and a scraper; a return air shaft is arranged at the corner of one ore room so as to be communicated with an upper horizontal return airway; each ore room is provided with an orepass used for the transmission of ores in the ore room; and a tunnel is respectively excavated along the strike direction above and below each ore room, the upper tunnel is used for ventilation connection, and the lower tunnel is used for ore removal connection. The invention is especially applicable to the mining of the gently inclined thin ore body of an underground mine, mining preparation has no requirements for undercutting projects, and the drill jumbos and scrapers are used for the operation, thereby achieving the characteristics of high degree of mechanization, high production efficiency, full-thickness continuous mining and low ore loss rate.

Description

technical field

[0001] The invention relates to a mechanized continuous mining method for underground mines, especially suitable for gently inclined thin ore bodies in underground metal mines. Background technique

[0002] Due to the limitation of the ore body occurrence conditions, the mining of gently inclined thin ore bodies cannot realize self-slipping by gravity, and it is difficult to realize large-scale mechanized operations. Gently inclined thin ore bodies have always been regarded as a difficult-to-mining ore body. In the traditional mining method, for the mining of gently inclined and thin veins, the problem faced by the wall caving method is that the mining process is complex, the efficiency is low, and the consumption of production materials is high, resulting in high mining costs; The problem is that the loss of ore pillars is relatively large, the ore recovery rate is low, and the utilization of resources is low. Sometimes support measures such as bolts are req...
