Specific implementation mode
Below in conjunction with attached drawing and specific embodiment, the present invention will be described in detail, herein illustrative examples of the invention
And explanation is used for explaining the present invention, but it is not as a limitation of the invention.
As shown in Figure 1, a kind of coal working face back production and hydraulic pressure applied to three dimensional physical similarity simulation experiment of the invention
Model support propulsion device, is made of two parts, and a part is hydraulic support pushing meanss, and a part is that coal-cutting drum is driven
Device.Including a pair of of pedestal 12, the movable bearing 11 of a pair of setting, a pair of movable branch are respectively perpendicular on a pair of of pedestal 12
By 10 interconnection of side guard plate between seat 11, and the spatial relationship of a pair of movable bearing 11 can be adjusted by adjusting spanner 9.
As shown in Figure 2,3, horizontally-supported on movable bearing 11 to have a hollow left and right push rod 16,17；A pair of of a left side,
Coal-cutting drum 7 and push bracket jack 1 are equipped between right push rod 16,17, coal-cutting drum 7, push bracket device 1 pass through blade support respectively
15 and push bracket plate 2 connect with left and right push rod 16,17；It is equipped in the end of hollow left and right push rod 16,17 and is connected to coal mining rolling
The rotary electric machine 6 of cylinder 7 is realized by the rotation and back production and the overall movement of suspension device of drive coal-cutting drum 7 to mining coal seam
Propulsion coal cutting effect；As stope propulsion constantly elapses forward, and seam mining information is acquired by camera, it is real
Now the mining engineering in coal seam is excavated.
Wherein, it is equipped with the connecting tube for the hydraulic oil pump being connected with push bracket jack 1 in left and right push rod 16,17 and mines
Transmission line roller 7 connected drive link and be connected with rotary electric machine 6 and camera.Cabling is equipped on left and right push rod 16,17
Slot 3,3 position of cabling channel can install miniature webcam.Transmission device between drive link and coal-cutting drum 7 is Worm Wheel System
The connecting tube of the pressure oil pump of connection, fluid-percussion model of isolated holder and push bracket jack is walked inside left and right push rod.And left and right push rod
16,17 length is corresponding with working face open-off cut length.11 top of movable bearing is equipped with fixing device 5, passes through fixed spiral shell
Fixing device 5 on movable bearing 11 is connect by bolt 4 with left and right push rod 16,17.Roller cover plate is equipped on coal-cutting drum 7
8, coal-cutting drum 7 is equipped with the blade in double-helix, is connected on rotary electric machine 6 by blade support.At 6 end of rotary electric machine
Equipped with coal-cutting drum opening and closing button a13, b14.
By 10 interconnection of side guard plate between a pair of movable bearing 11, and a pair is adjusted by adjusting spanner 9 can live
The spatial relationship of dynamic bearing 11, movable bearing 11 are height-adjustable.
Then three-dimensional similar simulation experimental carries out mining engineering excavation according to Practical Project condition and practical geological conditions
Simulation.In digging process, with coal mining activity, working face constantly moves forward, while being caving wound for prevent upper layer rock mass
People, hydraulic support also constantly can forward be elapsed as stope promotes, and the overlying rock in rear goaf can be gradually broken
It is caving.But in laboratory conditions, due to the scaling to Practical Project condition, Many times laboratory three-dimensional analog simulation is real
The height for testing middle exploitation working face tightly only has 10-20cm or so with wide, and face length can reach 1-1.5m or so, and work
It needs to elapse 0.5m or more as face.And a working face needs 20 or more fluid-percussion model of isolated holders, required pipeline occupancy to adopt
Dead zone position is caving form to goaf and has an impact.This allows for the back production in model coal seam, working face fluid-percussion model of isolated holder
Passage, working face fluid-percussion model of isolated holder and hydraulic oil pump connecting tube to goaf evade and goaf rock stratum is caving form
Observation directly affects the success or failure of experiment, and its these realization becomes to be increasingly difficult to the propulsion of working face.
Apparatus of the present invention solve the problems, such as this well, using steps are as follows：
After model is paved and dried, excavation simulation is carried out.Stope section haulage way and return air are dug first
Gallery, regulating device strut height make device meet the height of working face and inclination angle in three dimensional physical similarity simulation experiment model；
Then coal-cutting drum and cover plate, push bracket plate are connected on the push rod of both sides；Finally fluid-percussion model of isolated holder and miniature webcam are pacified
It sets on push bracket plate, the line arrangement of the connecting tube and miniature webcam of fluid-percussion model of isolated holder and hydraulic oil pump enters that both sides is hollow to push away
In bar, facility switching is opened, you can tested.
In an experiment, open rotary electric machine, coal-cutting drum made to rotate, using his power plant by back production and suspension device to
Experimental model working seam elapses, so that it may carry out back production to coal seam (pushing distance is set as primary recovery length)；When passage hydraulic pressure
When model support, first by corresponding fluid-percussion model of isolated holder be depressured, then control corresponding push bracket jack elapsed (passage away from
From being set as primary recovery length), finally fluid-percussion model of isolated holder is boosted roof supporting；When all hydraulic model support shifting frame is complete
At, that is, complete an advancing process.Then it is repeated in above step, you can complete the simulation excavated to working face.It crosses herein
On no influence that is caving in goaf in journey, while available miniature webcam observation goaf rock stratum is caving state.
The invention is not limited in above-described embodiments, on the basis of technical solution disclosed by the invention, the skill of this field
