Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent control technology for geophysical exploration and mining, and more specifically, to an explosive source and control method based on the simulation of seismic waves induced by an explosive source. Background Technology
[0002] Currently, research on high-precision explosive seismic source design methods mainly focuses on the design of explosive seismic sources from the perspective of explosive energy release, combined with practical engineering experience. However, due to the lack of theoretical guidance on explosive-induced seismic waves, current design methods struggle to meet the demands of refined seismic exploration if the excitation conditions change. Existing wavefield control technologies primarily address excitation through explosive parameters, explosive charge structure, and the selection of excitation strata. However, these methods are all implemented through engineering practice and lack a clear physical relationship or model, thus lacking universality. Therefore, it is necessary to propose an explosive seismic source and control method based on the simulation of explosive-induced seismic waves to at least partially address the problems existing in current technologies. Summary of the Invention

[0063] First, the parameters of the excitation layer medium and the parameters of the explosive source are extracted. Based on the parameters of the excitation layer medium and the explosive source, the explosive source-induced seismic wave model is obtained, and the suitability of the scheme for exploration is calculated and judged. If the scheme does not meet the exploration requirements, the judgment result is negative. Then, through forward progressive reverse control, the excitation depth or the explosive formula is changed, thereby controlling the changes in the parameters of the excitation layer medium or the explosive source parameters in reverse, correcting the explosive source-induced seismic wave model, and iteratively calculating whether the scheme meets the exploration requirements and judging it.

This method employs a forward-progressive, reverse-control approach, altering the excitation depth or explosive formulation to control changes in the parameters of the excitation layer medium or the explosive source parameters, thereby correcting the explosive source-induced seismic wave model. The process iteratively calculates whether the scheme meets exploration requirements and makes judgments; this continues until the exploration requirements are met, thus determining the explosive source. Based on the research of the theoretical model of explosive source-induced seismic waves, a design method for high-frequency, high-energy explosive sources is proposed, utilizing the relationship between explosive source characteristic parameters and seismic wave field amplitude-frequency characteristics. This method transforms the control objective of seismic wave amplitude-frequency characteristics in seismic exploration into the control objective of explosive source characteristic parameters through the explosive source-induced seismic wave model. Based on the explosive source characteristic parameter control objective, the explosive source formulation and excitation depth are designed, ultimately yielding a new type of explosive source that meets the needs of refined seismic exploration. This makes the explosive source characteristic parameters more accurate, the new explosive formulation more precise and reasonable, and enables large-scale, multi-point distribution high-frequency explosive source simulation.
