Direct cutting method and direct cutting machine for stone slabs in mines

Abstract

The invention discloses a method for directly cutting stone slabs in a mine pit and a direct cutting machine. The direct cutting machine includes a cutting frame on which a cutting head is installed. The machine head is equipped with a cutting machine head horizontal moving device; the bottom of the cutting frame is equipped with traveling wheels, and the cutting machine track is arranged under the walking wheels, and the cutting machine frame is equipped with a cutting machine for driving the traveling wheels to walk on the cutting machine track. walking gear. When cutting, the cutting is done directly in the bedrock in the pit. The effect is that large-scale lifting equipment is not required, blasting is no longer required during the mining process, the environment is no longer polluted, loading and unloading and transportation are safe, and transportation costs are saved. , so that stone resources will not be exhausted; stone resources will not be wasted, and the utilization rate of stone resources can reach about 95%.

Description

technical field [0001] The invention relates to a stone cutting and processing method, and also relates to a stone mining and processing device. Background technique [0002] Such as Figure 6 As shown, the current method of stone mining basically uses cutting machines to cut the stone ore in the pit horizontally, then cuts vertically, and then separates the cuboid stone squares by blasting or cracking. Each stone square weighs about Ten tons, and then transported to the stone processing factory at the foot of the mountain by means of transportation for cutting into pieces, then grinding, polishing, and slitting to complete the manufacture of plates. The disadvantages of the prior art are: [0003] 1. The stone material is too heavy, requiring large-scale lifting equipment, which poses great safety hazards in loading, unloading and transportation, and wastes a lot of transportation costs. In view of this, when the pit is deep, the safety supervision department will no longe...

AI Technical Summary

Problems solved by technology

[0003] 1. The stone material is too heavy, requiring large-scale lifting equipment, which poses great safety hazards in loading, unloading and transportation, and wastes a lot of transportation costs. In view of this, when the pit is deep, the safety supervision department will no longer allow continued mining, but as As the depth of the pit increases, the quality of the stone is getting higher and higher, resulting in unusable stone resources.

[0004] 2. In the process of mining stone materials, drilling and blasting are required, and accidents of gravel splashing and hurting people occur from time to time; moreover, explosives are dangerous goods controlled by the state. The purchase, storage, and use of them are extremely strict, with heavy responsibilities and high management costs.

[0005] 3. If there is a little defect in the stone square, it will become very easy to break. After the break, the stone square will be discarded as waste because it cannot be cut. The utilization rate of mine stone is only about 40%, and the waste of resources is extremely serious.

[0006] 4. A large number of stone processing factories are built in densely populated areas under the mountain. Cutting plates requires a large amount of cutting fluid, which is easy to pollute the environment, and dust is flying, and scraps are piled up like mountains

[0007] The reason why the cutting machine in the prior art cannot directly stone slabs in the pit is that when cutting stone squares, track fixing pin holes need to be marked on the quarry, and each cutting seam corresponds to two tracks, and the two tracks can only be fixed on the large Only on the stone can the track be stable. If the stone plate is cut, although one track can be fixed on the large stone, the other track cannot be fixed
