specific Embodiment approach 1

[0032] Specific implementation mode one: combine Figure 1 to Figure 6 To describe this embodiment,

[0033] An experimental device for studying the relationship between mining and ground subsidence, including an experimental platform 10, two experimental platform slide rails 11 and four side plates;

[0034] Such as figure 1 As shown, the four side plates enclose a cuboid frame, and the four side plates are successively recorded as the first side plate 1 to the fourth side plate 4; the cuboid frame is arranged on the test bench 10, and on the test bench, the cuboid The test bench slide rails 11 are respectively arranged on both sides of the frame, and a first slide block 12 is respectively arranged on each test bench slide rail 11, and a first slide bar 13 is respectively set on each first slide block, and the first slide bar 13 is vertical set above the first slider;

[0035] The sides of the two first sliders 12 are jointly connected with the synchronizing device 14, and...

specific Embodiment approach 2

[0040]In this embodiment, the second side plate 2, the third side plate 3, and the fourth side plate 4 are respectively divided into an upper plate, a middle plate, and a lower plate corresponding to the side plates by the first slot 51 and the second slot 53; The width ratio of the board, the first slot, the middle board and the second slot is (7-10):(0.5-1):(2-3):(7-9). Taking the third side plate 3 as an example, the third side plate is divided into an upper plate 31, a middle plate 32, and a lower plate 33 by the first slot 51 and the second slot 53; the width of the upper plate: the width of the first slot: the width of the middle plate Width: second slot width=(7~10):(0.5~1):(2~3):(7~9).

[0041] Other structures and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0042] In this embodiment, the width ratio of the upper board, the first slot, the middle board and the second slot is 10:0.5:2:7.

[0043] Other structures and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses an experimental device for studying the relationship between mining and ground subsidence, and relates to an experimental device for ground subsidence study. The problem of noexperimental device for studying the relationship between large-mining-height shallow coal seam mining and ground subsidence is solved. Four side plates are arranged on an experimental platform, and the experiment platform is provided with experimental platform slide rails; each experimental platform slide rail is provided with a first slide block, and each first slide block is provided with a first slide bar; each first slide bar is provided with a second slide block; two second slide blocks are respectively connected to two ends of the second slide bar; the second slide bar is provided witha third slide block, and the side face, facing a rectangular frame, of the third slide block is provided with a rolling cutter head driving device and a rolling cutter head, and the rolling cutter head driving device drives the rolling cutter head to rotate; one second slide block is provided with a second drive motor, and the second drive motor drives a lead screw to rotate to make the third slide block move along the second slide bar. The experimental device is suitable for auxiliary simulation experiments for studying the relationship between mining and ground subsidence.

Description

technical field [0001] The invention relates to an experimental device for ground subsidence research. Background technique [0002] Ground subsidence is a local downward movement (or engineering geological phenomenon) in which the elevation of the crustal surface is reduced due to the consolidation and compression of the underground loose strata under the influence of human engineering economic activities. An important factor causing ground subsidence is the mining of solid minerals. The mine subsidence is mostly distributed in the goaf of the mine, and the coal mining subsidence is the most prominent. There are about 20 provinces and regions in China where goaf collapses occurred, among which Heilongjiang, Shanxi, Anhui, Shandong, Henan and other provinces are the most serious. [0003] The phenomenon of ground subsidence caused by coal mining has affected the environment and ecology, and also affected living activities such as residential buildings in subsidence areas. ...
