Problems solved by technology
At present, a lot of research has been carried out on the theory and technology of mining loss reduction and post-mining ecological restoration, and some research results have been obtained. However, due to the large differences in geological mining conditions and surface vegetation in mining areas, the cost of monitoring the relationship between surface cracks and vegetation impact is very high. , The cycle is very long, and the lack of scientific, effective, and rapid research means and methods leads to unclear understanding of the interaction between surface mining fractures and vegetation growth and the research on the mechanism of influence, resulting in the current impact of surface mining fractures on the ecology of mining areas. Governance lacks scientific and economical technical methods
[0003] Laboratory simulation is also a commonly used research method, but because it is difficult to accurately simulate the on-site climate environment and the combination of vegetation and soil indoors, and due to the complex mining geological conditions and the influence of vegetation, it is difficult to determine the location and shape of mining fractures on the surface. Rock and soil mechanics and other related theories are used for calculations, which greatly reduces the accuracy of the research results

Embodiment 1
[0076] This experiment was carried out in the Shendong mining area, which is characterized by thin loose layers. Therefore, the experiment was carried out in the valley terrain area, and entered the interior of the rock and soil layer in the form of a flat tunnel from one side of the ditch. The design height is 25m underground. The schematic diagram of the implementation is as follows Figure 4 .
[0077] In the first step, this experiment is carried out on a 50m×50m wasteland beside a valley around the Shendong mining area. There are no artificial buildings and facilities in this area and there is a certain density of vegetation.
[0078] The second step is to divide the selected experimental site into no-vegetation area, herbaceous vegetation area, shrub vegetation area and vegetation-rich area. The vegetation in the and herbaceous vegetation area has been artificially processed. Regional distribution such as Figure 4 . In addition, an area of the same size as each veg...

The invention discloses a device for simulating and manufacturing earth surface mining-induced cracks. The device comprises at least two adjacent telescopic units and at least one leakage-proof net, each telescopic unit comprises a supporting bottom plate, a telescopic supporting column and a supporting top plate, one end of the telescopic supporting column is fixedly connected with the center of the supporting bottom plate, the other end is fixedly connected with the center of the supporting top plate, and supporting top plates of the adjacent telescopic units are connected through the leakage-proof net. The invention further discloses a method for simulating and manufacturing the earth surface mining-induced cracks and a field experiment method for researching the mutual influence relation between the earth surface mining-induced cracks and the vegetation growth condition. According to the method, the movement and deformation conditions of the overlying strata and the earth surface under various mining conditions can be simulated, the simulation effect is visual and consistent with the field climate and the ecological environment, the experiment conditions are stable and easy to control, and the mutual influence relation between the earth surface mining-induced cracks and the vegetation growth condition can be conveniently explored.
Description
technical field [0001] The invention belongs to the technical field of mines, and in particular relates to a device for simulating and manufacturing surface mining cracks, a method for simulating and manufacturing surface mining cracks, and a device for studying the mutual influence relationship between surface mining cracks and vegetation growth conditions. Field experiment methods and their applications. Background technique [0002] Surface cracks caused by mining will not only cause damage to surface buildings / structures, roads and buried facilities, but also cause surface water and soil erosion, which will cause surface vegetation degradation or decrease in species diversity. At present, a lot of research has been carried out on the theory and technology of mining loss reduction and post-mining ecological restoration, and some research results have been obtained. However, due to the large differences in geological mining conditions and surface vegetation in mining areas...
