Title:
COMBINED METHOD FOR EXCAVATING QUARRY STONE
Document Type and Number:
WIPO Patent Application WO/2016/127676
Kind Code:
A1
Abstract:
A combined method for excavating a quarry stone, comprising: using a large-diameter threaded-bead wire saw (11) for cutting to obtain half-separated quarry stone (3) having a suspended portion; and using a small-diameter threaded-bead wire saw (12) to cut the suspended portion of the half-separated quarry stone (3) to obtain a cut quarry stone. A gap cut by the large-diameter threaded-bead wire saw (11) can be provided for a threaded-bead wire of the small-diameter threaded-bead wire saw (12) to pass through, and can be adjusted to any position to adjust the size of the cut quarry stone, thus omitting a drilling step in a traditional cutting process, increasing a working efficiency, saving time, reducing costs, and increasing a utilization rate of resources.
