Integration of ground geophysical methods to characterize near‐surface aquifer zones within an active mine

Near Surface Geophysics, Volume 22, Issue 5, Page 521-538, October 2024.
Abstract Understanding near‐surface groundwater storage, flow patterns, surface and groundwater interactions in mining areas can assist in making mining more efficient and profitable. This is especially important in opencast mines affected by water inflows that may negatively affect production and increase mining costs. We map and characterize the near‐

Indicative microzonation map of the contact zone between the kenny hill and limestone formation using active, passive and hybrid MASW methods

IOP Conference Series: Earth and Environment
The impact of the far-field earthquake generated by the Sumatra-Andaman earthquake (Richter scale of 9.3) was also felt by Malaysians. The ground motion triggered by this earthquake is caused by the shear wave velocity (Vs), particularly at a depth of 30
