Problems solved by technology

[0005] In the simulation experiment, the fault is realized through the partition. The partition in the prior art is a whole board. For the fault fracture zone with a small inclination angle to the horizontal ground, when the simulation layer is laid, it is not conducive to The tamping of similar simulated materials; and after laying the simulated layers in the similar simulated space of the footwall and the similar simulated space of the upper wall, the board must be taken away to fill the transition zone. The paved simulation layer is deformed or collapsed, resulting in inaccurate simulation experiments or the need to flush and lay the simulated formation

Embodiment 1

[0047] In this embodiment, the partition mechanism used for fault fabrication in similar simulation experiments includes a split-type fault fracture zone partition 6 and a partition pressing mechanism for compressing the split-type fault fracture zone partition 6 in a similar simulation space , the split-type fault fracture zone partition 6 is located in the similar simulation space 7 and separates the similar simulation space 7 into a similar simulation space of the footwall and a similar simulation space of the hanging wall; as figure 1 shown.

[0048] like figure 2 and image 3 As shown, the split-type fault fracture zone partition 6 is spliced ​​by several partition units, and each partition unit includes a first partition 8, a second partition 9, an engaging part 11 and a supporting part. The supporting part is located between the first partition 8 and the second partition 9 and keeps the distance between the first partition 8 and the second partition 9 constant, and t...

Embodiment 2

[0055] In the actual simulation experiment process, it was found that the thickness of the fault fracture zone to be simulated was not fixed, so the fixed transition zone partition of Embodiment 1 (that is, the first partition 8 and the second partition in a single partition unit) was adopted. The distance between the two partitions 9 is fixed), the distance between the first partition 8 and the second partition 9 cannot be adjusted, and the partition unit needs to be remade for different geological conditions during use.

[0056] For this reason, in this embodiment, the distance between the first partition 8 and the second partition 9 is adjusted by an adjustable support member.

Embodiment 2-1

[0058] like Figure 4 As shown, the support member in this embodiment includes an independent support bolt 12 and an adjustment nut 13, and the adjustment nut 13 is fixedly installed on any one of the first partition plate 8 and the second partition plate 9 A blind hole 13-1 is provided on the inner plate surface of the first partition plate 8 and the other inner plate surface of the second partition plate 9; one end of the independent support bolt 12 is connected to the The adjusting nut 13 is threadedly connected, and the other end of the independent supporting bolt 12 is located in the blind hole 13-1. The support member also includes a support bar unit 14, and a through hole 14-1 is provided on the support bar unit 14; one end of the independent support bolt 12 is threadedly connected with the nut 13, and the other end of the independent support bolt 12 One end passes through the through hole 14 - 1 on the support bar unit 14 and extends into the blind hole 13 - 1 .

Abstract

The invention discloses a partition plate mechanism for making similar simulation experimental faults. The partition plate is a split-type fault fracture zone partition plate, the split-type fault fracture zone partition plate is located in a similar simulation space and divides the similar simulation space into a lower disk-like similar simulation space and an upper disk-like similar simulation space; the split-type fault fracture zone partition plate is composed of several partition plates units that are spliced together, each partition plate unit comprises a first partition plate, a secondpartition plate, an engaging member and a supporting member, the supporting member is located between the first partition plate and the second partition plate and keeps the distance between the firstpartition plate and the second partition plate unchanged, and two opposite side edges of the engaging member are respectively located in engaging grooves in two adjacent partition plate units; and theplate surfaces of the first partition plate and the second partition plate have the same size and the same shape. According to the partition plate mechanism disclosed by the invention, the partitionplates units can be removed one by one from bottom to top according to actual conditions, a similar material of the fault fracture zone is filled in time to avoid the situation that a paved simulationlayer deforms or collapses after the entire plate is removed.

Description

technical field [0001] The invention relates to the technical field of similar simulation of coal mine mining. Specifically, it is a partition mechanism used for similar simulated experimental fault fabrication. Background technique [0002] The stability of the surrounding rock of the tunnel is an issue that has attracted much attention during the tunnel excavation process. Once the surrounding rock becomes unstable, the tunnel will collapse, which will bring great losses to the construction. Faults are the most common unfavorable geological phenomenon during tunnel excavation, and the section with fault distribution is one of the most unstable sections of tunnel surrounding rock. [0003] For strata with unknown geological conditions, it is usually necessary to use a stratum simulation experiment device to simulate the stratum and geological conditions in order to provide guidance and technical support for later excavation work and reduce emergencies and accidents during ...
