Christopher Johnson

[CJ@RESPEC]

Hello all!

My name is Christopher Johnson and I hail from Rapid City, South Dakota. I am a project engineer for RESPEC. I have masters in geological engineering and just started my doctorate at South Dakota School of Mines and Technology. My expertise and background is in hydrogeology.

RESPEC has made its name in testing and geomechanical modeling of salt and potash for application in storage caverns and mines. As a consequence of this relation and my background, I am heavily involved in mine inflows in salt and potash mines. Usually in hard rock mines, mine inflows are just costly nuisances. However in salt and potash room and pillar mines, the inflow is rarely 100% saturated with respect to the ore material resulting in dissolution of salt/potash. This can result in significant pillar damage threatening the stability of the area.

My interests are quite varied and include mine inflow groundwater modeling, brine disposal groundwater modeling, geomechanical modeling, coupled hydraulic and mechanical responses, grouting technologies and methodologies, scale effects in hydraulic property estimates, and data and wavelet analysis.

Next year, I plan to attend and present at the 2010 IMWA conference and look forward to meeting everyone!

Cheers,
CJ
