Identifying geologic faults has always been the primary aim of geophysical prospecting work in coalfields. However, identifying minor faults of the top Ordovician limestone stratum (in coalfield areas) remains a significant challenge. As parts of the

A collapse column is a geological structure formed by the dissolution of a soluble rock layer under certain hydrogeological conditions. This forms a cavity, which is filled by the overburden. Collapse columns have a great impact on coal mining safety

The brittleness index (BI), which serves as a key reference for reservoir fracturing, is also an important quantitative index for the evaluation of coal-bed methane (CBM) reservoirs. To address the lack of research regarding this application of the B

In the areas where carbonate rocks expose to the near surface, there are several intractable issues in conventional surface seismic, including (1) weak reflection energy, (2) complex wave field and (3) serious static correction. Therefore, the seismi

The acoustic wave equation is an important basis for seismic wave propagation, imaging, and migration. This equation has led to the development of finite difference methods, but these methods are prone to numerical instability and grid dispersion pro

Love seam waves are generally applied to the current in-seam wave explorations. Rayleigh seam waves, however, are rarely used. The dispersion and amplitude features of Rayleigh seam waves are investigated using frequency dispersion analysis and numer

In this paper, a new approach is proposed for coalbed methane (CBM) reservoir brittleness index ( BI ) calculations. The BI , as a guide for fracture area selection, is calculated by dynamic elastic parameters (dynamic Young's modulus E d and dynamic

Dynamic elastic parameters of coal are closely linked to crack characteristics and are lithology indicators in seismic exploration. This experimental study measured ultrasonic wave velocity of coal samples considering both parallel (90°) and perpend
