Description

A kind of simulation seam mining device
Technical field
The present invention relates to a kind of simulation seam mining device.
Background technology
For being subjected to the distortion of mining influence rock mass, mobile and failure law after the extraction of research valuable mineral, often adopt the certain analog simulation of the likelihood ratio to test it is carried out qualitative analysis in test room.In test room, the simulation seam mining has certain limitation, and when particularly repeating to exploit in the simulation coal seam, multiple external influence factor can destroy rock mass movement and deformation rule.Find by inquiry, once there were human saw blade, plank, electric drill to wait and simulated seam mining, cause phenomenons such as goaf overlying rock movement and deformation rule distortion (not conforming to correlation theory), test model collapse easily, not only cause the certain economic loss, also wasted the plenty of time of testing crew.Though analog simulation test is a kind of effective ways of research mine pressure, the old way before still almost when the simulation seam mining now.
Summary of the invention
The invention provides a kind of simulation seam mining device, simple in structure, can simulate the exploitation in coal seam better, thereby the pressure of grasping better before and after the seam mining changes.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of simulation seam mining device, comprise model support, and be horizontally disposed with one group of rubber fluid power bag on the described model support, the top laying overlying rock of rubber fluid power bag; Be equipped with inlet and liquid outlet on each rubber fluid power bag, the inlet of rubber fluid power bag connects one way valve, expansion high-speed switch, pump, fluid box successively by pipeline, and the liquid outlet of rubber fluid power bag connects ball valve and liquid reserve tank successively by pipeline.
Described expansion high-speed switch is for comprising an entry switch and a plurality of gate out switch, the inlet of expansion high-speed switch is connected with pump by pipeline, the liquid outlet of expansion high-speed switch is communicated with one group of rubber fluid power bag by pipeline respectively, and the expansion high-speed switch is communicated with liquid reserve tank by pipeline.
Described rubber fluid power bag is rectangular layer cloth bag constructions, and a side of rubber fluid power bag is stretched out and is provided with the band input duct of inlet and the fluid pipeline of drag-out mouth.
Pipeline between described rubber fluid power bag and the one way valve is provided with pressure meter.
The upper and lower surface of described rubber fluid power bag is provided with a corrosion resistant plate respectively.
Four angles of described rubber fluid power bag and all be set to arcuate structure with the junction of input duct, fluid pipeline respectively.
The present invention can be according to institute's mining coal seam size and the each mining progress of testing crew, will be full of liquid, the identical rubber bag of size keeps flat on the model support, makes its upper surface on a horizontal plane, and then spreads overlying rock successively.An intake-outlet and a pressure meter are all arranged on each rubber bag, when working seam, only need open rubber bag successively, under the convergent force effect of rubber bag, liquid flows out, and according to manometric reading, the pressure that can grasp the seam mining front and back changes.In addition, can be according to seam mining thickness, the discharge of confined liquid, and then realize the separate zone production in coal seam.
The present invention is simple in structure, easy to use, can save the testing crew plenty of time, has improved operating efficiency.Through sampling test, its result of the test is very desirable, has avoided multiple influence factor.The present invention can be repeatedly used, and is applicable to various types of model supports.

The specific embodiment
Embodiment: shown in Fig. 1-4, a kind of simulation seam mining device comprises model support, is horizontally disposed with one group of rubber fluid power bag 3 on the model support, the top laying overlying rock of rubber fluid power bag 3; Be equipped with inlet 8 and liquid outlet 9 on each rubber fluid power bag 3, the inlet 8 of rubber fluid power bag 3 connects one way valve 5, expansion high-speed switch 1, pump 6, fluid box 7 successively by pipeline, and the liquid outlet 9 of rubber fluid power bag 3 connects ball valve 2 and liquid reserve tank successively by pipeline.Pipeline between rubber fluid power bag 3 and the one way valve 5 is provided with pressure meter 4.Rubber fluid power bag 3 is rectangular layer cloth bag constructions, and a side of rubber fluid power bag 3 is stretched out and is provided with the band input duct 10 of inlet 8 and the fluid pipeline 11 of drag-out mouth 9.Four angles of rubber fluid power bag 3 and all be set to arcuate structure with the junction of input duct 10, fluid pipeline 11 respectively.
The expansion high-speed switch is for comprising an entry switch and a plurality of gate out switch, the inlet of expansion high-speed switch 1 is connected with pump 6 by pipeline, the liquid outlet of expansion high-speed switch 1 is communicated with one group of rubber fluid power bag 3 by pipeline respectively, and expansion high-speed switch 1 is communicated with liquid reserve tank by pipeline.
During concrete enforcement, in order to realize effect preferably, the rubber fluid power bag that processes with special material have certain shape and thickness very little, be the distortion of restriction rubber fluid power bag upper and lower surface, rubber fluid power bag is put in the double-deck cloth bag consistent with seam mining thickness (m) and seam mining progress (b), respectively puts the corrosion resistant plate of a millimeters thick at the cloth interlayer corresponding to rubber fluid power bag upper and lower surface then.Sebific duct with certain intensity connects together rubber fluid power bag, pressure meter, one way valve, pumping plant, ball valve, sets up a rubber fluid power bag mould and intends the seam mining device.The concrete operations step is as follows:
(1), prepares certain density liquid according to the ature of coal attribute and the likelihood ratio.Connect power supply, check whether the liquid communication pipeline leaks;
(2) before being put on the model support, charge into certain amount of fluid earlier to rubber fluid power bag, guarantee that no air is residual in the rubber bag.Then, open inlet switch, charge into liquid successively, and the upper surface of guaranteeing rubber fluid power bag is on a horizontal plane;
