Device for exploiting stone based on water cutting slotting

Abstract

The invention discloses a device for exploiting stone based on water cutting slotting. The device comprises a plurality of symmetrically-arranged supporting bases, the left side and the right side of the upper end of each supporting base are symmetrically provided with an X-axis sliding rail, the upper end of the X-axis sliding rail is perpendicularly connected with a Y-axis sliding rail, a Z-axis sliding rail perpendicular to the X-axis sliding rail and the Y-axis sliding rail is arranged at the upper end of the Y-axis sliding rail, a guide block and a Z-axis sliding block which are matched with each other are arranged at the upper end and the lower end of the Z-axis sliding rail respectively, the lower end of the Z-axis sliding rail is connected with a swinging mechanism through a turning mechanism, a high-pressure pipe is connected between the swinging mechanism and the top end of the Z-axis sliding rail, and the lower end of the high-pressure pipe is connected with a matched cutting gun located at the lower end of the swinging mechanism. The device has the advantages that the structure is simple, dismounting and mounting are convenient, the automation degree is high, the labor cost is saved, high-pressure water jet is used for cutting the cut materials, the application range is wide, sections are smooth, no heat is produced, and the device is safe, quick, free of dust, low in noise and the like.

Description

technical field [0001] The invention relates to mining stone mining technology, in particular to a device for mining stone based on water cutting and slotting. Background technique [0002] There are several common methods of stone mining in mines at this stage in my country: mechanical saw cutting mining method, split mining method and blasting mining method. [0003] Among them, the mechanical saw cutting mining method directly saws the rock with various mechanical saws to separate it from the parent rock. The mechanical saws used include chain saws, circular saws or circular saws; circular saws and wire rope saws are mainly Used for mining square wall materials, chain saws and wire rope saws are mainly used for mining facing stone materials, but mechanical saws are only suitable for mining marble, limestone, tuff and other sedimentary rocks and metamorphic rocks with low hardness; Saws and circular saws have poor adaptability to hard nodules, and are generally used for...

AI Technical Summary

Problems solved by technology

The horizontal area of ​​rock separated by ordinary blasting can range from hundreds to 2,000 square meters. The efficiency is higher than that of the split mining method, but excessive rock fragmentation and hidden damage (micro cracks) often occur, and the yield of block materials only accounts for 25-25% of the blasting volume. 35%, slabs only account for 5%, and the strength of the stone is reduced, and it can be reduced to half of the original strength in severe cases, and the blasting mining method and split mining method are only applicable to rocks with structural planes
