Embodiment Construction

[0045] The present invention will be further described in detail below with reference to specific embodiments. In this embodiment, the high spatial resolution WorldView-2 satellite data is used as the detection data source, combined with figure 1 For detailed description, the specific steps are as follows:

[0046] Step 1: Establish image interpretation marks of surface mining fractures.

[0047] (1) The direction of fracture development is basically parallel to the direction of the working face;

[0048] (2) The cracks are linear and have fewer bifurcations;

[0049] (3) The value of the length-to-width ratio of the crack is between 30 and 60;

[0050] (4) Cracks have a cutting effect on the whole piece of ground.

[0051] Step 2: Select the Baode mining area where Kangjiata Village, Jiajialiang Village and Lujiagou Village are located in Baode County, Xinzhou City, Shanxi Province as the study area, and obtain the remote sensing images, goaf and working face vector diagram...

Abstract

The invention relates to a method for detecting surface mining cracks, comprising the following steps: firstly, establishing the interpretation marks of the surface mining cracks; then, obtaining remote sensing images of the research area and goaf vector diagrams, and preprocessing the remote sensing images and classification, to obtain the location of the mine mouth, as the logical information supporting the goaf and working face; to superimpose the remote sensing image, the vector diagram of the goaf and the vector diagram of the working face, to generate a buffer map, to delineate the existence range of mining fractures on the surface and Extract the area by clipping; perform high-pass filtering and direction filtering on the area according to the interpretation marks to weaken non-surface mining fractures; then use the region growing method to obtain suspected surface mining fractures, classify them by probability, and obtain the final surface mining fractures Crack, collect its coordinate position. This method can accurately identify surface mining fractures, provide important basic data for land reclamation and ecological restoration, and also provide scientific basis and technical support for damage compensation and fracture treatment.

Description

technical field [0001] The invention relates to the technical field of mine ecological environment monitoring, in particular to a method for detecting surface mining cracks. Background technique [0002] Surface mining fissures are a special type of ground fissures. Their formation is mainly caused by underground mining. It is easy to induce secondary geological disasters, change the micro-topography and micro-topography, and disturb the ecosystem, which not only restricts the development of the coal industry and economy. , and also caused serious harm to the construction of mining areas, people's life and property, and the ecological environment. To monitor and restore the ecological environment in the coal spontaneous combustion area, it is necessary to detect the surface mining cracks in the mining area. [0003] At present, the monitoring of ground fissures mainly uses ground fissure monitoring devices to directly measure them in the field. For example, "A dynamic moni...
