Embodiment Construction

[0050] The present invention is described in detail below in conjunction with accompanying drawing:

[0051] Stone roadway mining method of the present invention is carried out as follows:

[0052] a. Drilling, drilling four holes on the stone wall of the roadway, and taking out the core;

[0053] b. Cut four sides, use emery beaded wire saw to connect the above four holes and cut two adjacent holes into one side, and cut out four sides;

[0054] c. Cut the back and cut out the back of the stone with an emery beaded wire saw.

[0055] After cutting out the back of the stone, take out the cut stone with a forklift.

[0056] The key points of the inventive method are: c. cut the back, and cut out the back of the stone with an emery beaded wire saw.

[0057] As a preference, what can make full use of the stone is that the four holes are equidistantly arranged in parallel. In this way, the front of the stone is a square, with four holes at the four corners of the square, and t...

Abstract

The invention discloses a stone roadway mining method. The stone roadway mining method comprises the following steps of a, drilling four holes on the stone wall of a roadway; b, connecting and cuttingevery two adjacent holes of the four holes into one face through an emery bead stringing rope saw, and cutting into four faces; and c, sawing the back surface of the stone by using the emery bead stringing rope saw. The invention further discloses a device for realizing the method. The device comprises a host and a working machine tool, the host comprises a rack, a base, a drilling driving device, a feeding device, a cutting driving device and a water supply device, and the working machine tool comprises a drilling device, a four-surface cutting device and a back-surface cutting device. The invention further discloses a stone back face cutting device for the stone roadway mining. The stone back face cutting device comprises a back knife connecting rod and a back face cutting guide wheel set. By adopting the method and the device, the stone can be cut and separated from a mountain body without adopting any expansion device and blasting, the mining efficiency is high, and the back tangent plane of the stone is accurate and flat and is good in quality.

Description

technical field [0001] The invention relates to a stone material mining method, in particular to a stone material roadway mining method, and also relates to a device for realizing the method and a stone back cutting device thereof.
