Embodiment Construction

[0041] The mine cave adopts stone method, including:

[0042] Step 1, please refer to figure 1 At least six guide holes 11 are drilled with a large-diameter drilling machine 2 on the working face 1 of the mine area. The six guide holes 11 are arranged in two rows on the left and right, and each row has three guide holes arranged at intervals up and down. The depth of the guide holes is as follows: More than 3 meters, if the distance between two rows of left and right is more than 6 meters;

[0043] Step 2, please refer to Figure 2 to Figure 5 , exit the drilling machine 2, install the diamond wire saw machine 3 and the guide rod 32 with the first guide wheel 31, the guide rod 32 is inserted in the guide hole 11, and the diamond rope 34 is wound around the second guide wheel 33 and the first guide wheel 31 To cut out a top line 12, a bottom line 13 and two middle lines 14 on the working surface 1, and, two first vertical lines 15 and a second vertical line 16;

Abstract

The invention discloses a stone mining method for a mine hole. The stone mining method comprises the steps that at least six guide holes are drilled in the working face of a mine area; a top line, a bottom line, two middle lines, two first vertical lines and a second vertical line are cut on the working surface through the at least six guide holes; the first stone core is broken and taken out between the two first vertical lines; cutting is performed to take out the second stone core between the two center lines, and forming an upper ore material by the ore material between the center line onthe upper side and the top line; an abutting piece is inserted between the two middle lines so as to abut against the mineral material; back-cutting is performed on the upper ore material in a linearcutting mode; at least two supporting pieces are inserted between the two middle lines, the abutting pieces are processed so that the upper ore material can move to press against the supporting pieces, and the interval between every two adjacent supporting pieces forms a forking space for forking equipment to be inserted; and materials are taken by adopting forking equipment. The mineral materialtaking device has the advantages that mineral materials can be taken out through the forking device, large-size mineral materials can be taken out, and the material taking efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of mine cave mining, in particular to a method for mining rocks in a mine cave. Background technique [0002] Existing cave mining methods, such as 102678125B, include: [0003] Step 1, process the working face on the mine, drill four guide holes arranged at the four corners of the rectangle on the working face, cut a closed guide seam on the working face, so that the surrounding of the ore material is separated from the mine, and the guide holes are The hole is located on the guide seam; wherein: a horizontal seam and a vertical seam are cut out on the mineral material, the said pilot seam has an upper seam, a lower seam, a left seam and a right seam, and the said transverse seam and the upper seam are parallel And located under the upper seam, the vertical seam is parallel to the right seam and located to the left of the right seam; [0004] Step 2, set the bracket of the saw rope cutting equipment on th...
