Hard rock ore body mining equipment and mining method based on advanced pre-cracking of hole array

Abstract

The invention discloses a hard rock ore body mining equipment and mining method based on advance pre-cracking of hole arrays, wherein the mining equipment includes a walking mechanism installed at the bottom of the equipment, and slide rail mechanisms installed at the front and rear ends of the equipment. The ore body cutting mechanism for cutting the ore body, which is installed on the front slide rail mechanism and can move left and right, is installed on the side of the traveling mechanism for rock drilling and drilling of the ore body to be cut. It is a transportation mechanism for transporting the intercepted ore on the rear slide rail mechanism and can move left and right. The invention carries out slat-type reciprocating cutting of the ore body. During the operation of the equipment, the equipment is kept parallel to the mine wall, and the equipment does not need to turn around when the equipment reciprocates, and the mining operation is coordinated and continuous, which can improve the mining efficiency of hard rock mines; , During the operation of the equipment to cut the ore body, only the ore body cutting mechanism needs to move along the slide rail mechanism, and the equipment does not need to move.

Description

technical field [0001] The invention relates to the field of hard rock ore body mining equipment, in particular to a hard rock ore body mining equipment and a mining method based on advance pre-cracking of hole arrays. Background technique [0002] At present, the mining of mineral resources in metal mines still mainly adopts the drilling and blasting method. However, the traditional rock drilling and blasting method has exposed many disadvantages: the operating environment is dangerous, the production efficiency is low, the ore dilution rate and loss rate are high, and the blasting process is easy. Induced rockburst, water inrush and other serious disasters. With the increase of mining depth, the in-situ stress environment of the mining ore body is more complex, and the traditional drilling and blasting method can no longer meet the mining requirements. Therefore, the mining process must be improved to break the current hard rock mining method dominated by the drilling and ...

Problems solved by technology

However, the high cost of TBM is not conducive to achieving the highest economic benefits on the mine, and the TBM equipment is too large to operate flexibly in the stope with limited space in the underground mine. Therefore, if you want to realize the advantages of TBM excavation in the mining process , it is necessary to design a non-explosive mechanized mining equipment suitable for hard rock mining with the support of the current TBM theory
