Seismic signal processing is an important task in geophysics sounding and represents a permanent challenge in petroleum exploration. Although seismograms could in principle give us a picture of a geological structure, they are very contaminated by spurious signals and the ground roll noise is a strongly undesired signal present in the seismograms – it does not carry physical information about t...

Abstract Even after decades of intensive research, assessing rock slope stability remains a challenge. One reason for this is the spatial variability bridges (RBs) related to non-persistent, pre-existing geological structures, especially as detection RBs generally limited post-failure period. Thus, identification and classification their inclusion in numerical studies are demanding, yet essenti...

With the increasing depth of coal mining, quantitative evaluation degree geological structure development is becoming increasingly important for control mine water hazards in mining areas. Understanding complexity can improve safety and efficiency production. At present, various indicators cannot fully reflect faults folds, process usually affected by subjective human factors. In this paper, fr...

a considerable amount of energy is released in the form of shock wave from explosive charge detonation. shock wave energy is responsible for the creation of crushing and fracture zone around the blast hole. the rest of the shock wave energy is transferred to rock mass as ground vibration. ground vibration is conveyed to the adjacent structures by body and surface waves. geological structures li...

Applying 2D algorithms for inverting the potential field data is more useful and efficient than their 3D counterparts, whenever the geologic situation permits. This is because the computation time is less and modeling the subsurface is easier. In this paper we present a 2D inversion algorithm for interpreting gravity data by employing a set of constraints including minimum distance, smoothness,...
