Problems solved by technology

Therefore, in the case of the same mining width, the output of the production system is guaranteed to remain unchanged, and the frequency of equipment relocation in the fan-shaped steering face is more than doubled compared with parallel advancement, which further increases the number of continuous / semi-continuous mining process systems. time, which severely limits the application of continuous / semi-continuous mining process systems in open pit mines

Embodiment 1

[0049] The belt conveyor in the working face of the open-pit mine includes B1 belt conveyor 1 and B2 belt conveyor 2, and B1 belt conveyor 1 and B2 belt conveyor 2 are connected in series. The B1 belt conveyor 1 is arranged parallel or approximately parallel to the corresponding working surface, the head of the B1 belt conveyor 1 is at the center of the fan-shaped steering, and the B1 belt conveyor 1 transfers the materials on the working surface to the equipment of the end-side continuous transportation system ; The B2 belt conveyor 2 is arranged parallel or approximately parallel to the corresponding working surface, the head of the B2 belt conveyor 2 is connected with the tail of the B1 belt conveyor 1, and the materials on the working surface are transferred to the B1 belt conveyor 1. Working face mining equipment and supporting reloading equipment reload the excavated working face materials to B1 belt conveyor 1 or B2 belt conveyor 2.

[0050] The fan-shaped steering tran...

Embodiment 2

[0061] On the basis of Embodiment 1, an A1 belt conveyor 100 is added to the working face of the open-pit mine. The A1 belt conveyor 100 is arranged between the B1 belt conveyor 1 and its corresponding working surface, parallel or approximately parallel to the working surface and the B1 belt conveyor 1, and the head of the A1 belt conveyor 100 is turned in a sector At the center, transfer face materials to the equipment of the end-side continuous conveying system. The working face mining equipment and supporting reloading equipment transfer the excavated working face materials to the B1 belt conveyor 1 or the B2 belt conveyor 2 or the A1 belt conveyor 100.

[0062] In this embodiment, the fan-shaped steering transfer method of the belt conveyor system in the working face of the open-pit mine includes the following steps:

[0063] Step 1~4: with embodiment 1;

[0064] Step 5: Repeat Step 1 and Step 2;

[0065] Step 6: After the transfer of B2 belt conveyor 2 is completed, th...

Embodiment 3

[0073] On the basis of Example 1, a B3 belt conveyor 3 is added to the working face of the open-pit mine. The B3 belt conveyor 3 is arranged parallel or approximately parallel to the corresponding working surface. The head of the B3 belt conveyor 3 is connected to the tail of the B2 belt conveyor 2, and the materials on the working surface are transferred to the B2 belt conveyor 2. Working face mining equipment and supporting reloading equipment reload the excavated working face materials to B1 belt conveyor 1 or B2 belt conveyor 2 or B3 belt conveyor 3.

[0074] In this embodiment, the fan-shaped steering transfer method of the belt conveyor system in the working face of the open-pit mine includes the following steps:

[0075] Step 1: The mining and reloading equipment on the working face excavates the materials on the working face corresponding to B3 belt conveyor 3 on the B3 belt conveyor;

[0076] Step 2: After mining the working face materials corresponding to the B3 bel...

Abstract

The invention discloses a strip mine working face belt type conveying system and a fan-shaped steering moving method. The conveying system comprises n sets of belt type conveyors, and the n sets of belt type conveyors are sequentially connected in series and in lap joint from front to back. According to the fan-shaped steering moving method, excavating faces corresponding to all sets of the belt conveyors are excavated from back to front in sequence, and the excavating faces are compared with a moving rule line, so that the moving direction of an excavating device and moving of the conveyors on the rear portion are determined. According to the conveying system and the moving method, the production halt moving frequency of continuous / semi-continuous mining process system equipment is greatly reduced, and therefore the workload is reduced, and the production halt time is shortened.

Description

technical field [0001] The invention belongs to the technical field of open-pit mining equipment, in particular to a belt conveying system and a fan-shaped steering transfer method for an open-pit working face. Background technique [0002] The open-pit mine continuous mining process system is composed of bucket wheel excavators, self-moving loaders, receiving vehicles, working face belt conveyors and follow-up belt conveyors, etc. Single-bucket excavator, self-moving crusher, self-moving loader, receiving vehicle, working face belt conveyor and follow-up belt conveyor are sequentially connected in series and overlapped. Compared with the intermittent production process of single-bucket trucks in open-pit mines, the continuous / semi-continuous mining process system in open-pit mines has the significant advantages of continuous operation, high work efficiency, and low production costs. However, with the advancement of the working face, the working face equipment of the contin...
