Surface mining

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

Combination of surface and borehole seismic data for …

For each model, we generate two data sets—a surface data set (with sources and receivers at the surface) and a borehole data set (with sources at the surface and receivers in the borehole). The surface data are modeled as the response to an input band-limited spike with a maximum frequency of 55 Hz, and the borehole data are modeled with a Ricker wavelet with a peak frequency of 20 Hz.
