Description

Technical Field

[0001] The present application relates to the technical field of seismic exploration, and in particular to a comprehensive detection device for collapse columns. Background Art

[0002] A collapse column is a barrel-shaped column in a coal mine, formed by the strong corrosion of the underlying soluble rock layer by groundwater, which forms a large number of cavities, causing the overlying rock layer to become unstable, and then fall and collapse into the dissolution space. Since collapse columns can destroy the continuity of coal seams, they are prone to induce accidents such as water seepage and gas outbursts, which seriously affect the safe and efficient mining of coal mines. Therefore, the detection of collapse columns is of great significance.

[0003] At present, the general detection method is geophysical exploration, which uses coherence bodies, frequencies, phases and neural network properties to detect sinkholes. By extracting slices along the layers, the development of sinkholes can be intuitively displayed.

[0004] However, during the underground exploration process, the accuracy of geophysical exploration is reduced due to the presence of metal tools such as tunnel boring machines, anchor nets, and anchor rods on the underground excavation working face. Utility Model Content
