RESPEC PROJECT

The Wyoming Department of Environmental Quality, Abandoned Mine Lands Division (WY AML) selected RESPEC to continue the investigation and evaluation of the mining features associated with the historical Horse Creek Limestone Mine.

RESPEC engineers evaluated over 40 million cubic feet of underground workings that posed safety risks to the public. Using initial underground void scans, survey data, and historical mapping, we generated a 3-D model of the inaccessible underground workings and voids, verified with additional scanning. We collected 22 underground void scans using a Carlson C-ALS remote void scanning system. The 3-D models of the workings were used in conjunction with updated surface surveys to perform a stability analysis and determine safety in the concerned area. Once we identified priority areas requiring further investigation and potential remediation, our engineers began developing potential remediation solutions.

RESPEC is currently working with the WY AML to develop the next phase of investigation for the priority areas. Final remediation solutions will be developed and initiated once the priority areas have been fully investigated.
