The physical property of sebific duct and mechanical strength are mainly decided by the kind of its filling material and grain composition, and preferably, the compressive strength after described sebific duct fills the filler that can flow is 0.5-20 mpa.
Preferably, between described rock stratum and sebific duct, moisture absorption separation net is also provided with.By above-mentioned setting, avoid sebific duct and corroded by rock stratum.
Between described rock stratum and sebific duct, be also provided with squeeze board, be respectively equipped with two gathering sills in described pit inwall both sides, gathering sill bottom is positioned at sebific duct top and is close to sebific duct top, and the two ends of described squeeze board are separately positioned in the gathering sill of pit inwall both sides.By squeeze board, compacting operation is carried out to sebific duct, thus drastically increase the experiment effect of goaf simulation mining.
Compared with prior art, the utility model has following beneficial effect:
The utility model utilizes the sebific duct filling fine sand to fill up pit simulation goaf, sebific duct superincumbent stratum, then by hollow pipe, sand is put to sebific duct, its simulated experiment realizes very simple, convenient, and experiment effect is good, effectively overcome the pressure of can in prior art-pull-out method due to superincumbent stratum, can is caused often to be difficult to pull-out, experiment effect is not good enough, and paraffin-resistance burns method of melting and burns that to melt required time long, not only influence ecological environment, and, the defect of good experiment effect can not be obtained.
Accompanying drawing explanation
Fig. 1 is partial schematic diagram of the present utility model.
Fig. 2 is structural representation of the present utility model.
Wherein, the title that Reference numeral is corresponding is as follows: 1-main body, 2-sebific duct, 3-rock stratum.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
Present embodiments provide a kind of method simulating goaf exploitation, the method design principle of this simulation goaf exploitation is: adopt the sebific duct filling fine sand to fill pit, superincumbent stratum, then puts sand to sebific duct, simulates the exploitation in goaf with this.
The hardware that the present embodiment realizes the exploitation of simulation goaf is as follows: the main body with pit, and it arranges installation site for sebific duct provides; Sebific duct, Ruo Gangen, fills fine sand in every root sebific duct, and quantity, the radius equal-specification of sebific duct are determined according to the size of pit, and the size of pit is determined according to the goaf size of simulation, ties a knot in sebific duct two ends; Steel wire or iron wire, for knotting place at spiral rubber hose two ends, for two ends fit sealing; Hollow pipe, puts sand for inserting in sebific duct, and the external diameter of hollow pipe is less than the internal diameter of sebific duct; Rock stratum, is covered in the top of sebific duct, can experimentally object make.
Based on above-mentioned, concrete methods of realizing of the present utility model is as follows:
(1) according to treating that simulation goaf size is arranged some sebific ducts and tiles, sebific duct length, quantity, radius are determined according to the size in goaf;
(2) sand is filled in every root sebific duct, end, sebific duct two ends knotting with steel wire winding knotting place;
(3) tiling and filling husky sebific duct superincumbent stratum, and one of all sebific ducts section of end is exposed outside superincumbent stratum;
(4) the exposed end, one end outside superincumbent stratum of sebific duct is cut off;
(5) adopt hollow pipe to insert sebific duct from the end that sebific duct is cut off, the sand in sebific duct is flowed out by hollow pipe;
(6) repeated execution of steps (5), can simulate goaf exploitation.
Further, the present embodiment is provided with some isolation ridges in the pit bottom gap of main body, and described sebific duct is then arranged on the gap location between adjacent isolation ridge.Can be fixed sebific duct spacing by above-mentioned setting, avoid sebific duct each other because putting husky speed and extrude.
In the present embodiment, also squeeze board is provided with between rock stratum and sebific duct, be respectively equipped with two gathering sills in described pit inwall both sides, gathering sill bottom is positioned at sebific duct top and is close to sebific duct top, and the two ends of described squeeze board are separately positioned in the gathering sill of pit inwall both sides.By squeeze board, compacting operation is carried out to sebific duct, thus drastically increase the experiment effect of goaf simulation mining.
The utility model adopts sebific duct to coordinate hollow pipe to put the husky simulation realized goaf, the pressure of superincumbent stratum does not affect puts husky action normally, thus effectively overcome the pressure of can in prior art-pull-out method due to superincumbent stratum, can is caused often to be difficult to pull-out, the problem that experiment effect is not good enough; On the other hand, hollow pipe is put and husky is realized convenient, simple to operate, and response is in time, thus overcomes paraffin-resistance and burn method of melting and burn that to melt required time long, not only influence ecological environment, and, the defect of good experiment effect can not be obtained.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on above-mentioned design concept; for solving same technical matters; even if some making on architecture basics disclosed in the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
