Description

technical field [0001] The invention relates to the technical field of applied geophysical radar wave detection, in particular to a mining borehole radar advance water detection and forecasting device and method. Background technique [0002] Coal mine advanced water exploration is mainly to detect whether there are harmful geological structures or rich water bodies and water-conducting channels in front of the tunnel, roadway excavation direction and working face by direct or indirect methods at the head of the tunnel, and provide detailed information for safe tunneling. detection data. [0003] At present, the direct method used for advanced detection of coal mines is the drilling method, and the indirect method is the geophysical method. Although the drilling results of the drilling method are relatively reliable, the construction period is long and the cost is high, which has a great impact on the normal production of tunnels and roadways. [0004] At present, the geoph...

AI Technical Summary

Problems solved by technology

[0005] The above geophysical methods are all drilling detection methods after tunnels, roadways, working faces or boreholes are drilled. Various metal facilities such as steel support, bolt support, and conveyor belt support have a great influence on the observation results of the three-pole method and the mine transient electromagnetic method. The parameter is single, only one parameter of resistivity is used, and the ability to eliminate multiple solutions is poor, resulting in multiple solutions

If the above-mentioned multiple methods are used in combination, the forecasting cost of advanced forecasting will be greatly increased; and the drilling detection method performed after the hole is drilled is unable to detect because the coal seam is soft and the drilling hole often collapses.

The seismic wave method mainly solves the problem of the interface of the geological structure, but cannot explain the water-richness of the structure; the borehole electrical method and the borehole electromagnetic method cannot judge and explain the size and distance of the water-bearing body
