- W2393485287 abstract "Since the particularity of the ore rock structure and lithology in multi-metal mining area,it's difficult for seismic reflection to form a continuous and stable and gentle reflecting interface,and the application of seismic reflection method are generally not effective.This paper established a initial velocity model by using the first break information which was received by means of the ground long arrangement,then utilized the first arrival ray tracing forward modelling and SIRT velocity tomographic inversion technique in the complex surface and medium conditions,which did not rely on the existence of the bed interface,to obtain the velocity field information about the structure and lithology changes of ore bodies or rock bodies,and then the distribution range and exhibition characteristics of the detection target were acquired.The testing results show that the method is feasible,and anomalous changes of the velocity inversion coincide with the results of geological survey.Since the detecting depth of this method can reach hundreds of meters,it could provide a reliable basis for the detection of shallow insidious ore bodies and structures." @default.
