During the past three to four decades, the mining industry has closed several mines and portions of mines. In the process, a lot has been learned about the technological side of mine closure. Some of the knowledge has been gained through successes and some through failure. Regardless, the industry has applied sound science and engineering to many of the technical challenges of mine closure and has made significant progress in solving many of those aspects. However, the industry is still working to develop and implement creative ways to mitigate the socioeconomic impacts of mine closure.
