Abstract

Mining is necessary for maintaining society’s current lifestyle and it will continue to grow at a global scale, even if the use of some mineral resources may decline. However, mining can be detrimental to public health and safety, and may cause damage to the environment (on-site and off-site effects), due to mining-related removal of soils and vegetation and concomitant increased erosion, creation of large amounts of wastes and/or associated acid mine drainage (AMD) or increased suspended sediment loads in downstream waterways. The generation of solid and liquid wastes and the discharge of these wastes on to land and into waterways are arguably the greatest impacts on the environment associated with mining.

Geomorphology provides a very useful framework for understanding and quantifying stability and changes in erosion and sedimentation at those sites, which is the root of the release to wastes to the environment. But also for designing and building stable functional landforms in mine rehabilitation, process that can be improved through modelling and monitoring. These landscape design and reconstruction techniques are called Geomorphic Rehabilitation. This new branch of knowledge and practice dates back only to 1980, and has been expanded mostly since their successful application at active coal mines in New Mexico (United States) since the year 2000. GeoFluv – Natural Regrade is one common method of Geomorphic Rehabilitation, but not the only one. On its counterpart, Australia has the most extensive set of scientific papers and handbooks dealing with landform design and stability in mine rehabilitation, mostly due the application of the Landscape Evolution Model SIBERIA for this purpose. Current cutting-edge research in this field tries to merge landform design and modelling methods and packages, increasing their capabilities.

The question whether mining can be truly sustainable is difficult to answer. However, the presenter’s thesis is that it is very difficult to be sustainable if it does not properly consider landform design and modelling to reach functional stability. This is the catchment scale, since most landscape and ecological processes are driven by hydrological dynamics within drainage basins – the most common unit of landscape organization at ice-free lands on Earth.

The presentation will be illustrated with Geomorphic Rehabilitation examples from the European Union —where this technique is already considered Best Available Technique for the Management of Waste from the Extractive Industries—and from South America.

Dr. Yaron Ziv visits USA Natural Regrade reclamation sites

Dr. Yaron Ziv of Ben-Gurion University of Negev, Israel, toured Natural Regrade reclamation sites on March 2017 with Nicholas Bugosh, developer of the GeoFluv™ reclamation design method that is used in Carlson Software’s Natural Regrade.

Bugosh accompanied Dr. Ziv as they viewed more than 2000 acres of mining-disturbed lands at active and fully reclaimed mine sites to see how companies are efficiently constructing these functional landforms during mining and how the land has responded after reclamation.

Dr. Ziv, a spatial ecologist, was very impressed that the reclaimed land provided ecological niches that support a diverse ecosystem and that the sites have withstood extreme storms (approaching 200-year recurrence interval) without requiring maintenance and repair.

Following the tour, Dr. Ziv said he was excited about the opportunities to use Natural Regrade with the GeoFluv method for proposed large mining projects in the Israeli desert.

GeoFluv Training held in Singleton

On Tuesday 13th August Nicholas Bugosh held a GeoFluv Training Session in Singleton NSW. The first session of the training was open to all interested parties and attracted about 20 people involved in the local mining industry.

Additional Training was provided for Natural Regrade users – including a field trip to the Hunter Valley to collect landform input values.
