Abstract
The senior engineering class at Carroll College was tasked with completing the closure of an abandoned mine site in Perry Canyon, 32 miles outside of Reno, Nevada. This project will be done for the Bureau of Land Management and the design will be implemented in the near future. The task of the waste rock team was to design the cap and cover system for the existing waste rock pile next to the historic mine adit. The completion of this design includes regrading the waste rock pile slope, picking a geosynthetic design for the cap system, and locating topsoil material suitable for the effective cover system. The regrading of the waste rock pile will work in tandem with revegetation efforts to help prevent erosion of the new cover soils. The geosynthetic system will prevent acid mine drainage from leaking off the waste rock pile and into the ground and surface water of the surrounding site. This project will be done using CAD software and surface data provided by the University of Nevada. The geosynthetic system will be implemented from research done through Agru America Geosynthetics, and the final design will include detailed drawings of the cap and cover system, as well as the associated cost analysis.
