Continuous rotating and vibrating cutting equipment realizing pregrooving and used for hard rock ore body and construction process of equipment

Abstract

The invention discloses continuous rotating and vibrating cutting equipment realizing pregrooving and used for a hard rock ore body and a construction process of the equipment. The equipment comprises ore body grooving mechanisms, ore body cutting mechanisms, ore shoveling and transportation mechanisms, a walking mechanism, a hydraulic pump station, a hydraulic rationing and control system, hydraulic vibration exciters and an operation room, wherein the ore body grooving mechanisms cut the ore body from inside to outside, so that pre-grooves are formed, stress is eliminated, crack development is promoted, and free surfaces of the ore body are increased; the ore body cutting mechanisms cut the ore body in a rotating and vibrating manner, the cutting directs of the front and rear cutting mechanisms both face the pre-grooves, and rock and ore breaking is realized mainly in a diagonal tension failure manner. Batten type reciprocating cutting is performed on the ore body, while the equipment reciprocates, the grooving mechanisms continuously pre-groove the ore body, the cutting mechanisms cut the ore body in a rotating and vibrating manner, and the shoveling and transportation mechanisms continuously shovel and transport ore which is cut off; the mining work is synergistic and continuous, the equipment does not need to turn around, and the low ore loss rate and the low dilution ratio can be guaranteed.

Description

technical field [0001] The invention relates to a hard rock ore body cutting device, in particular to a pre-groove hard rock ore body rotary vibration continuous cutting device and a construction process thereof. Background technique [0002] At present, the traditional rock drilling and blasting method that dominates the recovery of hard rock ore bodies has increasingly exposed serious defects such as operational danger, low production efficiency, low energy utilization rate, and large derivative damage, which is contrary to the principles of safety and efficiency required by modern industry; at the same time, blasting It is also an important factor in inducing disasters such as rockburst and water inrush. Therefore, in order to adapt to the rapid development of the national economy, it is necessary to break the pattern of hard rock mining, which is a basic industry dominated by drilling and blasting, and reform the mining process. [0003] As we all know, non-explosive me...

Problems solved by technology

However, compared with the characteristics of low strength, low hardness, light and brittle, and developed fractures of coal rocks, non-coal hard rock ore bodies generally have the characteristics of high strength, high hardness, high abrasiveness, and good integrity. After contacting the ore body, it is difficult for the rock machine tool to intercept the ore efficiently at one time. Instead, it repeatedly rubs against the ore, which easily generates high temperature. The concentration of dust and respirable mineral dust is high, which leads to high mining costs and poor working environment, which ultimately leads to direct restrictions on the application of non-explosive mechanized continuous mining in hard rock mines
