Of these, eight mines are conventional underground operations at 900-1100 m depths. Solution mining is used at three sites where the ore is buried to 1500 m depth or where this methodology was a necessary remedial action responding to flooding of an underground dry mine. Two new underground mines are currently under construction.

Coal mining in the UK peaked in 1912–1915, and then experienced a wave of expansion and contraction. The last deep coal mine in the UK closed in December 2015. Coal mining has left behind a legacy of mining hazards (geohazards) that, if not properly managed and investigated, represent a risk to new construction and development.

Geohazards utilizes 2-D and 3-D imaging techniques capable of depths of 100 feet or greater to best characterize the subsurface. Ground Penetrating Radar (GPR) Using a range of up to four different antennae frequencies, GPR surveys can detect anomalous subsurface features, underground storage tanks and voids under concrete slabs.

Seismic exploration has become the standard tool for detection of geohazards prior to the advancement of mining into new areas. Without seismic, and specifically 3D seismic, it is possible that each of the conventional mines in Saskatchewan would have encountered significant water inflows as a result of mining into undetected geohazards.
