A leak-proof physical similarity simulation experiment frame

Abstract

The invention discloses a leakage-proof physical similarity simulation experiment frame and belongs to the field of energy engineering. The leakage-proof physical similarity simulation experiment frame is characterized by comprising an experiment frame, an upper baffle plate, a lower baffle plate and a middle baffle plate, wherein screw holes are formed in the left end and the right end of the experiment frame; a rectangular transparent baffle plate of an upper baffle plate limiting device is mounted at the lower end of the upper baffle plate and fixed on the front and rear sides of the experiment frame; a rectangular transparent baffle plate of a lower baffle plate limiting device is mounted at the upper end of the lower baffle plate and fixed on the front and rear sides of the experiment frame; the middle baffle plate is located between the upper baffle plate and the lower baffle plate and is limited in the horizontal direction by the upper baffle plate limiting device and the lower baffle plate limiting device to move left and right, thereby being capable of moving forwards with advancing of the working face, and collapsed rocks in a goaf are prevented from falling into the experiment frame. The experiment frame can effectively prevent simulated rock blocks from leaking out of the experiment frame, so that an experiment effect is improved, a model is prevented from toppling over, and the leakage-proof physical similarity simulation experiment frame is simple to use and low in experiment cost.

Description

technical field [0001] The invention relates to a physical similar simulation experiment frame. Specifically relates to a leakage-proof physical similarity simulation experiment rack. Background technique [0002] In mining, geology and other industries, in order to study the movement and stress distribution of the overlying strata after mining, similar materials are often used to lay a plane physical similarity experimental model on the plane physical model test frame, and excavate the ore body to simulate the actual strata movement. Case. However, in the plane physical similarity simulation experiment, after the simulated ore body is mined, the simulated rock stratum collapses in the goaf and is easy to leak out of the test frame, which leads to the distortion of the physical similarity simulation experiment results, and even causes the model to be unevenly stressed and sideways. To dump. Therefore need a kind of physical similar simulation experiment frame that prevent...

Problems solved by technology

[0003] At present, the commonly used method is: set a baffle on one side of the test stand, that is, set a baffle on one side, and the baffle fits the model completely to block the experimental model, and artificially simulate ore body mining on the other side. This method can only Effectively block one side, but cannot prevent similar materials falling on the mining side of the simulated ore body, which may easily cause uneven force on the top of the model and cause instability and dumping; or set baffles on both sides of the test frame, front and rear baffles They all fit the model completely. Multiple retractable jacks are set under the physical simulation frame. The shortening of the jacks can simulate ore body mining. The mining progress of the physical simulation experiment is limited, and the production cost of the experimental frame is relatively high
