Description
Technical Field
The utility model relates to a stone material mining equipment especially relates to a stone material tunnel mining equipment, still relates to a stone material back cutting device.
Background
At present, projects such as engineering construction, house decoration and the like use a large amount of stones, particularly natural stones. Thus, stone mining is important, and the quality of the stone and the economic benefits of stone mining associated therewith depend on the stone mining method.
At present, the stone mining method mainly comprises the following steps:
firstly, open pit mining. The equipment used in surface mining mainly comprises:
1. the mechanical stone mining system is composed of a diamond bead saw as main mining equipment and auxiliary equipment such as a large-aperture hydraulic or pneumatic drilling machine, a pneumatic rock drill, a hydraulic jack, a stone machine, a hydraulic jack push bag, a pneumatic jack push bag, a mast crane, a loader and the like, and is a mechanical stone mining system for mining stone by a widely used sawing method at present.
2. On the basis of a diamond bead saw mining system, an arm type saw can be arranged to form a stone mechanical mining system. There are two types of arm saws: the first is a chain arm type saw machine, and the second is a diamond mining band saw machine. The chain arm type machine uses hard alloy as a cutting tool, and is suitable for mining marble and limestone light-colored stone materials with the hardness below the medium hardness. The structure and motion principle of the band sawing machine for diamond mining are similar to those of a chain arm type sawing machine, and the cutting tool of the band sawing machine is a diamond tool bit. The band saw for diamond mining features high cutting speed and can saw hard marble (serpentine) or silicified marble.
3. The whole diamond bead saw and the movable mine stone cutter combine the mining system. During mining, a bead stringing saw is adopted to firstly separate and cut the horizontal plane of the separating body, and the movable mine stone cutter performs cutting of vertical saw slits with the depth of 650-. Or separating the horizontal plane by combining a horizontal dense hole array and splitting, and then splitting the split and separated body to produce the rough material.
And secondly, mining the roadway. Compared with surface mining, roadway mining has obvious advantages: 1. the method reduces or basically does not damage vegetation on the surface of the ore body and the natural environment, and is an environment-friendly stone mining method; 2. the mining of the barren material at the position of the ore body which can not be or is difficult to reach in the open-pit mining can be realized; 3. because large-scale covering layer stripping is not needed, the comprehensive mining cost of the hole mining stone is lower than that of open pit mining; 4. under the guarantee of modern design means, mining machinery and mature mining process technology, the stone is guaranteed to be mined on the premise of not damaging the natural environment, utilizing stone resources to the maximum extent and optimizing stone patterns; 5. the method can avoid the ore body parts of ore body cracks and chromatic aberration, selectively mine the optimal stone pattern parts of the ore body, and leave the unnecessary ore body parts as safe ore pillars, so that higher waste material rate can be obtained, and the waste of stone resources is reduced; 6. the method realizes that the high-quality stone is not limited by the weather condition when being mined in the alpine region.
However, the existing stone roadway mining method is not widely used, mainly because the back of the stone is not cut but is cracked in the mining process, so that the stone is easily damaged, such as cracking and the like, and the quality and the mining benefit of the stone are influenced. The reason for this is that there is no suitable back mining dedicated equipment. At present, the equipment for tunnel mining mainly adopts a wire saw device matched with a splitting device and the like. The equipment can completely cut the upper, lower, left, right and front five faces of the stone, the sixth face of the stone, namely the back face, can not be cut by using a saw, and the back face of the stone can be separated from a mountain body only by adopting a splitting device and matching with an expanding and splitting wedge through a hydraulic power device. Therefore, the practical operation has great limitation, the stone is difficult to be completely and clearly cut, the back surface is irregular and inaccurate, the stone is wasted, and the stone is easy to break, especially when the stone has cracks or has low density.
The equipment suitable for accurately mining the stone roadway is found, the stone can be accurately and efficiently mined, and the technical problem which is urgently solved by technical personnel in the field is solved.
