Evaluation and Remediation of an Abandoned Gypsum Mine
Journal of Geotechnical and Geoenvironmental Engineering, 2010The remediation measures taken for an abandoned gypsum mine in the Italian Alps are presented. The mine consists of four levels, excavated by the room-and-pillar method in an evaporitic formation. The two lower levels were flooded by water coming from adjacent strata after mining ended about 30 years ago. The dissolution process affecting the submerged

MASW Imaging of an Abandoned Minnesota Mine
Symposium on the Application of Geophysics to Engineering and Environmental Problems 2006, 2006Several sinkholes have occurred on the site of a large, public historical center structure in northern Minnesota and ground subsidence has caused structural damage to some of the center's buildings. The structure was built over mine dump material, underlain by glacial drift and a Cretaceous iron formation.

Shallow Seismic Investigations of an Abandoned Mine
Proceedings, 2012The near-surface rock structure that covers an abandoned marl mine nearby the village of Montevecchia (Italy) was investigated through a combination of seismic surveys performed in two different survey campaigns. The methods selected for these investigations were Refraction Seismics and Multichannel Analysis of Surface Waves (MASW).

Geophysical Characterization Of An Abandoned Gold Mine
16th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2003The North State Goldmine in High Point, North Carolina was active from the early 1800’s to around the turn-of-the-century. It is now part of a residential area that is under development. The primary purpose of the geophysical surveys conducted on the site was to identify voids and other features that may present geotechnical hazards during development.

Legacy Issues and Abandoned Mines
2017The chapter summarises the principal problems associated with current approaches to closure planning. Then it discusses the critical relationship between effective mitigation and management of mining legacies and abandoned mines. In the third section, I review global and Australian initiatives on mining legacies.

With the promulgation of Bill 71 in June 1991, the closure of mines in the province of Ontario must meet stricter environmental conditions. The legacy of open shafts and derelict sites should be brought to an end. A new Abandoned Mines Abatement Program was also introduced in 1991 to deal with clean-up of abandoned sites that have reverted to the Crown

Mine fires occur on abandoned mine lands throughout the U. S. coal fields. They threaten the health and safety of the local populations and consume a non-renewable natural resource. In general, mine fires are the most costly abandoned mine lands problem to mitigate. In active mines, fires are quickly extinguished by the mining company as they present a

Abandonment of Mine Tailings Ponds
Canadian Water Resources Journal, 1986In response to growing concern about the long-term environmental impact of abandoned mines and their tailing ponds, regulating authorities are beginning to request that abandonment plans be submitted with license applications. This paper suggests criteria that such plans should meet and emphasizes the need to ensure that adequate funding will be ...

The residual risk of an abandoned mine
2013It is well known that the mine legacy is a serious concern to present communities. The high risk associated with subsurface voids together with the lack of knowledge of geometric and geomechanical features of former mining areas make abandoned underground mines one of the current challenges for countries with a long mining history.
