Embodiment Construction

[0035] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Such as Figure 1-5 As shown, the present invention provides a simulation detection test device for mining damage and repair in a coal mine, which includes a frame body 1 , a moving track 2 , a fixing member 3 , a side plate 4 and a partition plate 5 . in:

[0037] The frame body 1 includes universal wheels 12, left bottom plate 14, right bottom plate 15, reinforcement plate 16 and upright column 17, wherein the left bottom plate 14 and right bottom plate 15 are hingedly connected by bolts, and the bolts are respectively in the circles reserved outside the interface between the two. Installed in the hole and fixedly connected by iron sheet.

[0038] Four universal wheels 12 are respectively installed on the bottom of the left base plate 14 and the right base plate 15. Considering the bearing capacity of the universal wheels 12, t...

Abstract

The invention discloses a coal mine area extraction damage and restoration simulation detection testing device comprising a frame, fixing members, and side boards. The frame comprises a bottom board, vertical columns, and reinforcing boards. The bottom board comprises a left bottom board and a right bottom board, which are boards having the same size, and can be separated from each other. The front edges, the rear edges, and the side edges of the left bottom board and the right bottom board are provided with drill holes, and the left bottom board and the right bottom board are connected together in a hinged manner by bolts. The four corners of the bottom board are provided with the vertical columns, which are fixedly disposed on the corners of the bottom board. The upper part of the frame and the middle parts of the vertical columns are provided with the reinforcing boards by the fixing members. The side boards are respectively in the shape of a topless cuboid, and the side boards are disposed in the frame, and in addition, the side boards in different directions and the side boards and the frame are connected together by the fixing members. The coal mine area extraction damage and restoration simulation detection testing device is used as a carrier of researching a correlation between ground penetrating radar echo signals and extraction overlying strata structure changes, ground fissures, and land reclamation engineering quality factors after damages, and a multifunctional proper device and a research method are provided for the monitoring and the control of the coal mine area extraction damages.

Description

technical field [0001] The invention relates to a physical simulation test device for mining damage, in particular to a simulation test device for mining overlying rock structure changes, ground fissures and ground penetrating radar signal inversion in land reclamation projects in coal mine areas. Background technique [0002] According to relevant data calculations, by 2050, the proportion of coal resources in my country's one-time energy consumption will still reach 50%. The large-scale development of coal resources has also caused land subsidence, damage, occupation, and frequent ground fissures. Empirical data show that the national average for every 10,000 tons of coal mined, the surface subsidence is 0.2km2, while in Shandong Province, the degree of this subsidence will reach 3 mu / 10,000 tons. In my country, the coexistence and superposition of cultivated land resources and coal resources is more obvious. The area of ​​coal-grain compound area accounts for 10% of the c...
