Embodiment 1

[0027] Embodiment 1: Experimental model of deep concave open pit mine with single bucket vehicle mining process;

[0028] see figure 2 As shown in the figure, it is a schematic top view of the model of the deep concave open-pit stope of the present invention. The deep-concave open-pit stope has a stope depth of 80-100 m, the coal seam 11 is arranged in a stepped shape, and the height of the stepped slope surface 15 is 10 m. The slope angle of the step is 65°, and the width of the working plate is 42m.

[0029] An inclined transport channel 14 is set on the top moving stope line of the deep-concave open-pit stope 1, along which the vehicle runs; the length of the inclined transport channel 14 is 125m, the longitudinal gradient is 8%, and the road width is 10m ; Slope distance 30m.

[0030] A mining face 12 is set on the step, and the bucket excavator 13 and the belt vehicle 16 collect coal at this position; a belt conveyor 17 is connected to the step of the deep concave open...

Embodiment 2

[0039] Embodiment two: single bucket-automobile-tape semi-continuous mining process deep concave open pit experimental model;

[0040]In this embodiment, the depth of the stope is 200m; the slope angle of the steps is 65°; the length of the inclined transport channel is 125m, the longitudinal slope is 8%, and the width of the road for vehicle ground transportation is 10m; The 12 steps in the lower part of the stope are equipped with four semi-fixed crushing stations, one for every three steps, and the main transport belts are set along the inclined direction in the western fixed gang to undertake the transportation of the four crushing stations respectively. The peeled material is transferred to the ground tape machine, and then the ground tape machine will transfer the peeled material to the tape machine of the southern dump for disposal. The main coal transport belt is set up in the eastern fixed gang, and a semi-fixed raw coal crushing station is set up every three coal min...

Embodiment 3

[0041] Embodiment 3: single bucket-vehicle mining process hillside open-pit mine experimental model;

[0042] In this embodiment, the vertical height of the hillside is 80m, the inclination is 20°; the length of the inclined transport channel is 125m, the longitudinal gradient is 8%, and the road width is 10m; Stope ratio: length: width = 2.5: The top-side transportation stope line is provided with an inclined transportation channel, which goes straight every three steps from bottom to top and then turns back.

[0043] In the present invention, the coal seam outcrop is below the level of 60m from the surface, the east-west trend, the coal seam dip angle is 6° and is nearly horizontal, the inclination direction is from north to south, and the horizontal thickness of the coal seam is 30m.

[0044] Every three peeling steps in the upper part are loess steps, forming a combined step, which can be directly excavated without blasting a bucket wheel excavator. The height of the combi...

Abstract

The invention relates to a deep-concave strip mine production model system which comprises a deep-concave excavating plant, a refuse dump, ground transportation roads and a raw coal washing field. The deep-concave excavating plant is a coal excavating plant arranged on a coal seam in a simulating mode; as simulation, multiple bucket wheel excavators conduct continuous stripping work on the north working pit edge and conduct coal production work in a deep place, stripped objects in the excavating plant are conveyed to the refuse dump on the south part of the ground through a belt conveyor arranged on the east end pit edge to be discharged through a dumping plough, and run-of-mine coal in the excavating plant is conveyed to the raw coal washing field on the west side of the ground surface boundary through a belt conveyor arranged on the west end pit edge to be processed. By means of the deep-concave strip mine production model system, tests under various construction process conditions can be simulated, the improvement can be carried out in real time according to the mining requirements, and overall adjustment can be conducted on a mining site.

Description

technical field [0001] The invention relates to the field of open-pit mining, in particular to a mining model system for deep-concave open-pit mines. Background technique [0002] The deep concave open-pit mining system in the prior art has a relatively complex structure, generally including deep concave stopes and corresponding excavation, transportation and dumping equipment. In actual open-pit coal mining, if the mining process or system is improved, the engineering It is more complex and cannot be improved in real time according to the needs of mining, nor can it be adjusted as a whole on the mining site. [0003] In view of the above-mentioned defects, the creator of the present invention finally obtained the present creation after a long period of research and practice. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a deep concave open-pit mining model system to overcome the above-mentioned technical defects. [0005] In order ...
