LONG-TERM COAL MINE RECLAMATION RESEARCH YIELDS GOLD MINE OF RESULTS

In 2000, the Research Council concluded a 29-year surface coal mine reclamation research program with Smoky River Coal Ltd., near Grande Cache, Alberta. It could be the longest running program of its kind in North America. The objective was to develop environmentally acceptable, practical and cost-effective reclamation techniques for high elevations.

When the project began in 1971, reclamation research was in its infancy. The project included development of soil handling practices and salvage strategies, plot studies to determine suitability of various plant materials and the use of state-of-the-art climate monitoring equipment to establish climatic conditions for use in the planning reclamation programs. 

Technology transfer occurred throughout the project, including the transfer of results from plot scale to operational scale, input into reclamation plans and adaptation of mining equipment for use in reclamation activities. The research has resulted in numerous presentations and publications, as well as four national and international awards. The project has also provided increased levels of confidence to regulators and the public about the long-term success of reclamation of disturbed land at high elevations.
