Abstract

The invention discloses an underground cutting mining method of process ore. The method concretely comprises the following steps: (1) firstly, digging a tunnel in the side of an ore body, and transversely tunneling from the tunnel to the ore body so as to form a chamber access, wherein the chamber access penetrates through the ore body, and the upper and lower sides of the ore body are provided with two free surfaces; (2) drilling in one free surface, and respectively drilling in four corners of the free surface so as to obtain four drill holes which penetrate through the two free surfaces; (3) passing a wire saw through the drill holes in the same side; (4) connecting the wire saw to a wire cutter, starting the wire cutter, driving the wire saw to cut the ore body between the drill holes, so that the ore body is completely separated from surrounding ore bodies or surrounding rocks. The underground cutting mining method is simple in operation, small in labor intensity, good in safety, and high in economic benefits. The ore exploited by the method disclosed by the invention is regular in shape, large in size and high in process value.

Description

technical field

[0001] The invention relates to a mining method, in particular to an underground cutting mining method for craft mines such as pyrophyllite, fluorite and jade, and belongs to the technical field of mining. Background technique

[0002] At present, with the continuous improvement of people's material living standards, high requirements are also put forward for spiritual life, and the pursuit of artworks is also changing with each passing day. Carving high-art handicrafts must have high-quality craft materials. Since high-grade and high-quality craft materials of minerals are often stored underground, underground mining is often due to factors such as less free surface of the ore body, narrow mining operation space, and high hardness of the ore body. In order to separate the ore body from the ore body or surrounding rock, blasting is generally used for mining. Due to the blasting method for mining, although some high-quality lump ore is relatively large in siz...
