Problems solved by technology

In the process of mining, personnel, machinery and equipment enter and exit the stope, go up and down the patio, and then blast, there are many safety hazards such as landslides, roof fall, and gun smoke poisoning; The damage to the body causes the stability of the stope roof and the surrounding rock of the hanging wall to decline again, and the above-mentioned safety accidents are more likely to occur, especially the open-stop mining method and the filling mining method, which require a large number of people to enter and exit the stope frequently, so that the mining operation Safety hazards exist from time to time, and it is difficult to guarantee the safety of employees

Embodiment 1

[0094] In order to solve the problem that the existing rock cutting machine cannot penetrate deep into the rock, the embodiment of the present invention provides a self-propelled rock cutting machine, such as Figure 1-4 As shown, it includes a body 1, and the body 1 is provided with a cutting mechanism 2, a traveling mechanism 3, and a rotating mechanism 4.

[0095] In this embodiment, the moving mechanism 3 drives the body 1 to move. During the movement of the body 1, the cutting mechanism 2 can cut the rock, and the body 1 can also walk in the slot cut by the cutting mechanism 2, so as to cut deep into the rock. The slewing mechanism 4 can drive the body 1 to rotate as a whole, so as to complete the turning and rotating cutting operations of the body 1 .

[0096] In this embodiment, the body 1 is a rectangular frame structure, that is, the interior of the body 1 is a hollow structure, which is used to install and support the cutting mechanism 2, the traveling mechanism 3 an...

Embodiment 2

[0148] Self-propelled rock cutting machine, different from Embodiment 1, the structure of the chainsaw 202 of this embodiment is as follows Figure 16 As shown, the shape of the through groove 202-2-1 opened at the front end of the chain saw plate 202-2 in this embodiment is circular, that is, the chain saw 202 in this embodiment is a circular hollow chain saw.

Embodiment 3

[0150] Self-propelled rock cutting machine, different from Embodiment 1, the chain saw 202 of this embodiment is a bearing-type chain saw, such as Figure 17-18 As shown, it specifically includes a chainsaw sprocket 202-1, a chainsaw plate 202-2, a chainsaw bearing 202-4, and a drive chain 202 wound around the chainsaw sprocket 202-1 and the chainsaw bearing 202-4 -5.

[0151] like Figure 18 As shown, the chain saw bearing 202-4 of this embodiment consists of a bearing outer circle 202-4-1, a bearing inner circle 202-4-2, and a bearing outer circle 202-4-1 and a bearing inner circle 202- The bearing balls 202-4-3 between 4-2 are composed; the longitudinal section of the bearing outer circle 202-4-1 in this embodiment is H-shaped, and the outer wall of the bearing outer circle 202-4-1 is sprayed with diamond abrasives , the bearing inner circle 202-4-2 is accommodated in the inner cavity of the bearing outer circle 202-4-1, so as to form protection for the bearing inner circ...

Abstract

The invention provides a self-propelled rock cutting machine and a mechanical cutting mining method, and belongs to the technical field of mining, the self-propelled rock cutting machine comprises a machine body, the machine body is provided with a cutting mechanism, a walking mechanism and a rotating mechanism, the cutting mechanism is rotatably arranged on the machine body, and the walking mechanism is arranged on the machine body; the grooving machine is used for grooving a rock and cutting the rock in all directions; the walking mechanism is provided with a contact face, and the contact face of the walking mechanism can abut against the groove wall of the open groove so as to drive the machine body to walk. The swing mechanism is provided with a contact face, and the contact face of the swing mechanism can abut against the groove wall of the open groove and is used for being matched with the walking mechanism to drive the machine body to rotate. According to the mechanical cutting mining method, a self-propelled rock cutting machine is used for cutting mining. The rock cutting machine disclosed by the invention can continuously and autonomously walk and operate in the thin-wall rock, and can also reach a specified position to carry out cutting operation, so that mechanical mining is realized, and the safety of staff is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mining, and specifically relates to a self-propelled rock cutting machine. In addition, the invention also relates to a mechanical cutting mining method. Background technique [0002] Existing mining methods are mainly divided into open field mining method, caving mining method and filling mining method. The open-field mining method is suitable for the ore body with good stability of the ore and surrounding rock, allowing the upper wall to be partially exposed without causing the surface collapse; the caving mining method is suitable for the ore body with large thickness and large area, and the surface can be recovered after mining. Collapsed ore body; filling mining method uses materials to fill the stope that forms the goaf to prevent the collapse of the stope ore body, the surrounding rock of the upper and lower walls, and the mining method of preventing the surface from collapsing. [0003] However, ...
