Embodiment Construction

[0046] Such as Figure 1 to Figure 10 As shown, a device capable of simulating surface subsidence in a coal mine teaching area includes a simulation frame 1 and a coal seam 2 and other multiple rock formations arranged therein. An aquifer 3 is arranged above the coal seam 2, and an aquifer 3 is arranged in the aquifer 3 The aquifer simulation system is provided with an overlying rock collapse monitoring system on the simulation frame 1, and the overlying rock collapse monitoring system includes a ruler 402 and a horizontal laser instrument 401 arranged on the simulation frame, and the horizontal laser instrument 401 is arranged on the left side of the simulation frame 1 side, the height is equal to the top height of the final aggregate. When the overlying rock collapses due to coal seam mining, measure the collapse point vertically with the ruler 402. The distance from the mapping point of the horizontal laser instrument 401 on the ruler 402 to the collapse point can be Direct...

Abstract

The invention discloses a device capable of simulating the surface subsidence of a mining area in coal mine teaching, and the device comprises a simulation frame (1), a coal layer (2) and a pluralityof other rock stratums, wherein the coal layer (2) and the plurality of other rock stratums are disposed in the simulation frame (1). A water-bearing layer (3) is disposed above the coal layer (2), and a water-bearing layer simulation system is disposed in the water-bearing layer (3). The simulation frame (1) is provided with an overlying rock subsidence monitoring system, and the overlying rock subsidence monitoring system comprises a straight rule (402) and a horizontal laser instrument (401) disposed on the simulation frame (1). The horizontal laser instrument (401) is disposed at the leftside of the simulation frame (1), and the height is equal to the final height of the top where an aggregate material is laid. The device provided by the invention has the functions of measuring a subsidence angle and simulating the permeability coefficient of the water-bearing layer (3). Meanwhile, the device is simple in structure, is compact in function, is low in test cost, is high in test efficiency, and is high in precision.

Description

technical field [0001] The invention relates to the field of coal mines and teaching, in particular to a device capable of simulating ground subsidence in mine areas in coal mine teaching. Background technique [0002] Due to the complex and changeable mining geological conditions, there are many factors affecting mining engineering mechanics, and the mining technology of each mine is complex and changeable, some problems cannot be obtained by computer numerical simulation alone. Satisfactory results. It cannot completely and accurately reflect the specific conditions and the rock formation movement caused by mining during the mining process, so the physical similarity simulation experiment still plays an important role in the mining engineering research process by virtue of the advantages of accurate and reliable rock formation movement in the reverse mining process. status. [0003] The literature "Simulation Experimental Research on Three-dimensional Similar Materials in...
