Abandoned Mine Lands (AML)

JFC has been involved in Wyoming mine subsidence issues and projects in Rock Springs, in excess of 42 years, beginning with the catastrophic event in the Mountain Fuel area in 1968 (Pennsylvania Avenue, Connecticut Avenue, Rhode Island Avenue); the surface reclamation of mine sites located in the Rock Springs, Lionkol, Superior, Winton, and Reliance areas in the early 1980s; and then continuing in 1988 to date through the AML 6A-III and 6A-VII grouting projects. Our involvement in the various assessments and stabilization programs in Rock Springs, since AML’s initial involvement in 1988, allows JFC to be ahead of the learning curve regarding any past or future subsidence issues and abatement.

JFC is able to offer an informed perspective with regard to evaluating subsidence mitigation work.  With our knowledge of Rock Springs undermined areas, we are able to offer thorough first-hand knowledge of the issues, and the required background information needed to make the desired informed assessments.

JFC has also integrated their historical information into a GIS database. They developed the database using attribute tables that contained the grouting information on a hole-by-hole basis. For more information, please click the button below.
