Sawing wire cutter for cave mining of mineral materials and cave mining method for mineral materials

Abstract

The invention discloses a sawing wire cutter for the cave mining of mineral materials and a cave mining method for mineral materials. The sawing wire cutter comprises a support, a guide track, a main motor, a feed mechanism and a sawing wire cutting mechanism. The sawing wire cutting mechanism comprises a sawing wire and at least one extending part, the main motor is transmissively connected with the sawing wire, so that the sawing wire can cut a cut surface, at least part of the extending part is located between a working face and the cut surface, the working face is parallel to or intersects the cut surface, at least one first guide pulley is arranged on the extending part, the tangent line of the first guide pulley is matched with the cut surface, and the sawing wire is led from the cut surface to the main motor by the first guide pulley. Since the guide pulley arranged on the extending part can lead the sawing wire to the working face from the cut surface, the cut surface is separated from the working face, the cut surface can be machined as long as the main motor, the guide track, the feed mechanism and the like are placed on the working face, so that the back of mineral material can be cut off from a mine mountain, the sawing wire cutter can be utilized for cave mining, the cut surface is smooth, and the cutting efficiency is high.

Description

technical field [0001] The invention relates to saw rope cutting equipment and a mining method for mineral materials. Background technique [0002] At present, stone mines need to realize vertical pit mining or horizontal tunnel mining. In the case that the working face has only one free surface, take horizontal tunnel mining as an example: for the top, bottom, left, and right sides, and the back, a total of five surfaces must be aligned with the main rock mass. Only by separating can the stone be taken out from the original large rock mass to realize cave mining. The applicant's previous invention patent "A Method and Equipment for Stone Mine Cave Mining" has been practiced, and the cutting and separating effects on the four sides of the upper, lower, left, and right sides are all good. For the separation of the back side: use the air pressure after cutting the guide seam with a cutting machine The bag is loaded into the guide seam, and then pressurized to break the back t...

AI Technical Summary

Problems solved by technology

Since the backside is cracked by air pressure, the section is uneven, and sometimes breaks along the original cracks of the stone, so it is necessary to process a new working face in the subsequent process for re-hole mining, which will cause complicated and heavy workload
