Abstract

The invention discloses a coal monitoring method and device based on a reverse time migration imaging algorithm and a storage medium, and the method comprises the steps: obtaining source wave field data transmitted at each moment of a target region, and receiving reflection echo data corresponding to the source wave field data; determining target receiving data based on the reflection echo data and pre-detected receiving data, and performing reverse continuation on the target receiving data based on a preset pseudo-spectrum time domain algorithm to obtain receiving wave field data at each moment in the target area; performing wave field decomposition on the source wave field data and the receiving wave field data to obtain decomposed source wave field data and decomposed receiving wave field data; performing cross-correlation imaging on the decomposed source wave field data and the decomposed receiving wave field data at the same moment to obtain each cross-correlation imaging result; and carrying out filtering processing on each cross-correlation imaging result, and determining a final reconstructed image of the target area. The technical problem of low monitoring accuracy of a complex geological structure is solved.

Description

technical field [0001] The present application relates to the technical field of physical exploration, in particular to a coal monitoring method, equipment and storage medium based on a reverse time migration imaging algorithm. Background technique [0002] The coal mine environment is complex. In order to avoid coal accidents, it is necessary to detect the diseased body in advance, that is, to detect the position and shape of the diseased body in advance. At present, the detection method of the underground diseased body is usually ground-penetrating radar detection method. , while the traditional ground penetrating radar migration methods mainly include Kirchhoff migration and one-way wave equation migration. Among them, the one-way wave equation is based on the two-way wave equation for one-way wave decomposition, which can only be established accurately when the velocity is constant , in complex geological anomalies with steep dips, high and steep dips cannot be imaged we...
