Specific implementation mode
Below with reference to attached drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, main body frame 1 installs altogether 8 pieces of side panels, i.e., 2 pieces of side panels, 3 pieces of pressures are installed in each side Plate, 3 hydraulic stems, 1 handwheel, a secondary track chain, 3 oil fuel tubes, 2 pieces of transparent panels.Track chain 9 is by 2 transmission chains Item forms, and arrangement is moved towards along working face.As shown in Fig. 2, the surrounding of magnet ring 5 fixes four stainless steel elastic sheet metals, it is allowed to card Moved with the movement of rock stratum in drilling, the probe of magnet ring survey meter 14 can with specific location residing for effectively perceive magnet ring, It obtains adopting movement value before and after rock stratum is subjected to displacement.
Before experiment starts, the main body frame 1 of experimental rig is put onto a plane, side panel 3 is fixed on frame On, one layer of rectangular tube 6 is then fitly laid on the steel plate of experimental rig bottom, and the analog material needed for testing is carried out in advance It prepares, is taped against after preparing on rectangular tube 6, notice that the upper surface of analog material should smooth out in order to applying in testing below Pressure is uniform, while spreading analog material, it should which homogeneous vertical places 16 pvc pipes on rectangular tube, is used as observing in the future.Material After material is completed, needs after waiting for the physico-mechanical properties of analog material to reach required condition, proceed by the work of next step Make.First inbuilt 16 pvc pipes are extracted out, are careful not to destroy hole wall;Then strata displacement monitoring sleeve 4 and magnet ring 5 are put Enter in 16 simulation drillings.Next pressure plate 7 is placed on the upper surface of analog material, by hydraulic oil by oil fuel tube 12 to liquid Oiling increases pressure in compression bar 8, is used for simulated formation pressure.By the rotation of handwheel 10, pressure plate is adjusted along track chain 9 7 pressing position is to achieve the effect that uniformly to press.It is simulated with this by extracting the rectangular tube 6 below analog material out simultaneously The progradation of coal seam stope.After simulation stope promotes and the pressure on ground reaches preset effect After fruit, the side panel immediately ahead of testing stand is changed, transparent panel 2 is installed, in order to further observe and record strata movement.By It is extracted in rectangular tube 6, forms the mined out space of simulation, and due to the pressure of simulated formation pressure, it is similar to cause top The fracture of simulation material is fallen, while this process can make pre-set magnet ring 5 fall together, therefore every time twice In adjacent observation, according to the position for detecting the same magnet ring 5, that is, the vertical position of the simulation rock stratum representated by magnet ring 5 is known Shift one's love condition.To obtain each difference in inside rock stratum that can not be with the naked eye observed under three-dimensional condition rock stratum displacement number According to.
Embodiment is only to illustrate the technological thought of the utility model, and protection scope of this utility model cannot be limited by this, It is every according to the utility model proposes technological thought, any change done on the basis of technical solution each falls within this practicality Within the scope of novel protected.
