Application of Point Scattered Seismic Imaging Method in Seismic Exploration of Ashele Copper Mine
Most of the metalliferous deposits result from the superposition and reconstruction of multiple mineralization in multiple stages,with metallic ores mostly found in metamorphic and magmatic rocks.These ore deposits typically have poorly defined boundaries and the ore bodies are generally small in size,and sometimes even smaller than one seismic wavelength.In such cases,seismic scattered or diffraction waves are more likely to occur,while reflected waves are relatively weak.Consequently,conventional seismic reflection exploration meth-od,based on the geological model of horizontally layered sedimentary rock,is no longer ap-plicable.Instead,processing technologies that focus on scattered waves are more suitable.This article examines seismic exploration at the Ashele copper mine,employing scattered wave processing method to analyze the collected seismic data based on the physical model of point scattering.The resulting seismic profile exhibits a higher signal-to-noise ratio and pro-vides richer geological information than the conventional seismic reflection wave processing method.This work offers a certain reference value for carrying out seismic exploration in similar regions.
