Description
Technical field
The present invention relates to a kind of ore-rock excavation simulation technology, more particularly to a kind of three-dimensional analog simulation experiment of three-dimensional loading
Excavation system support system.
Background technology
Analog simulation experiment is the laboratory procedure with the theory of similarity, dimensional analysis as theoretical foundation, can effectively be solved
Certainly mine pressure, surrouding rock deformation and movement law in underground space development activity, the research topic such as overlying strata are disrumpent feelings.With its experiment effect
Fruit intuitively advantage and be widely used in the departments such as water conservancy, mining, railway.Although similarity simulation experiment should engineering research neck
With extensive, however, the simulated test in numerous mine pressure, in terms of overlying strata move disrumpent feelings rule focuses mostly in areal model, this
There is different with the three-dimensional stress state residing for live rock stratum.
During coal mining, the disrumpent feelings and its stress distribution of overlying rock is a process for dynamic change, with work
Make the propulsion in face, working face front occurs stress redistribution.In the process, country rock is deformed, moves, destroys, overlying strata
Peak stress also can forward be shifted with the advance of the face, until reaching new stress equilibrium.Development and science and technology with society
Progressive, the mankind are increasing to the exploitation demand of the underground space, however, underground space development process is built more compared with ground
Complexity, is influenceed greatly by geological conditions.Be necessary by three-dimensional analog simulation experimental study and development for tunnel speedy drivage with
The rig for testing of support technology.
Existing three-dimensional analog simulation pilot system promotes the research of underground excavation project to a certain extent, but still
Shortcomings part, topmost shortcoming is exactly that can not carry out mechanization, the visualization of large area to ore bed in process of the test
Exploitation.For example, patent " three-dimensionals of ZL 201210376520.3 loading large-scale three dimensional analog simulation pilot system " discloses a kind of three
To loading large-scale three dimensional analog simulation pilot system, the loading of three-dimensional anisobaric is capable of achieving, while can carry out such as Mine Stope, water
The large-scale dimension such as electric chamber, gas storage in salt caverns Excavation simulation is tested.The development of the rig for testing has obtained certain breakthrough, so
And, for real-time, visualization space mechanization excavation is accomplished by a kind of system adaptable therewith in realizing process of the test.For
This, it is necessary to develop the support system of a kind of simple structure, compact in design, to adapt to space requirement of the excavation simulation to system.
The content of the invention
The purpose of the present invention is aiming at the deficiencies in the prior art, there is provided a kind of three-dimensional analog simulation experiment opening of three-dimensional loading
Digging system support system, the system is made up of the supporting unit that multiple is set up in parallel, and supporting unit is by L-shaped supporting base
Horizontal segment and vertical section are respectively provided with jacking cylinder or jacking cylinder, and pipe bending cylinder or pushing tow cylinder, and oil cylinder or cylinder
Using thin type structure, to form the support system of compact in design, to adapt to the space requirement of excavation simulation, and its simple structure.
For research three-dimensional loading environment under cover stress distribution, disrumpent feelings, face surrounding rock with stress in stope progradation dynamic change
Provided convenience etc. process.
To achieve the above object, the present invention is adopted the following technical scheme that.
A kind of three-dimensional analog simulation experiment excavation system support system of three-dimensional loading, the supporting list being set up in parallel by multiple
Unit's composition;Supporting unit includes L-shaped supporting base, vertical raising plate and horizontal push plate;Supporting base and vertical raising plate are logical

Layer is carried out along the movable type cutting in face length direction, it is adaptable to the simulation exploitation under the conditions of three-dimensional load test, to obtain
The test data of three-dimensional loading environment Imitating exploitation is obtained, camera is set in system can easily realize visual machine
Tool melts digging.When using, after only need to accordingly being transformed the existing chamber for realizing three-dimensional load test system.Cutting
During cutting, feed of cutter plate forms the cutting that cutting process completes the whole short transverse of working face palisades, and palisades are cut
Bottom surface after cutting forms the extension of just mining face bottom surface, and top surface forms the extension of working face top surface, and support system top surface is located at
Working face top surface lower section, to ensure making smooth advances for support system.Wherein, support system is in the supporting list being set up in parallel by multiple
Unit's composition, the vertical climbing structure of supporting unit is used to be formed the interim fixation of supporting unit, the horizontal push-and-pull knot of supporting unit
Structure is used to elapse excavation system, and forms follow-up of the supporting unit with the system of excavation.It is multiple in systematic procedure is excavated in passage
Supporting unit forms interim fixed simultaneously;During the follow-up of supporting unit, control system can in two ways to supporting list
Unit is controlled, and one is all supporting lists under conditions of excavation system itself is moved by frictional resistance without generation position
Unit follows up simultaneously, to obtain excavation efficiency higher;Another kind is to ensure to excavate system position stabilization during follow-up, by a part
Supporting unit keeps temporal hold state, and then another follow-up excavation system, then formed temporarily by the supporting unit for having followed up
It is fixed, complete the supporting unit follow-up of remainder;Finally, after all supporting units form interim fixation, then carry out next
The excavation of circulation.Because supporting unit is respectively provided with jacking cylinder or jacking by the horizontal segment and vertical section of L-shaped supporting base
