Description

Technical Field

[0001] This invention relates to the field of intelligent simulation technology of seismic sources in rock exploration and mining, and more specifically, to a system and method for simulating seismic waves induced by explosive sources. Background Technology

[0002] Currently, seismic exploration targets are smaller and buried deeper, placing higher demands on the accuracy of seismic exploration. The accuracy of seismic exploration is affected by the seismic waves generated by the explosive source. However, because the scale of the seismic wave field propagation range in seismic exploration is much larger than the scale of the explosive cavity, existing technologies for analyzing the wave field characteristics within a limited range, based on theories and numerical simulations of explosive cavity formation and near-field explosive stress waves, can only analyze the wave field characteristics within a limited range. Existing technologies focusing on the near-field of the explosion cannot obtain a direct relationship between far-field seismic waves and the source; while technologies focusing on far-field seismic waves can only assume the near-field is an elastic cavity, failing to establish a relationship between far-field seismic waves and source parameters. Existing classical cavity source models neglect the explosive process, leading to problems such as the inability to establish the relationship between the characteristic parameters of the explosive source and the amplitude-frequency characteristics of the initial elastic waves. Therefore, it is necessary to propose a simulation system and method for seismic waves generated by an explosive source to at least partially solve the problems existing in current technologies.

This provides impact protection and accurate detection and calculation of seismic wave pressure. It prevents the pressure sensor group from being damaged by the blast shock wave and accurately detects and calculates the elastoplastic boundary range and elastoplastic boundary pressure. It solves the technical difficulties related to the relationship between near-field and far-field seismic waves and the seismic source.
