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.
