Historically, solid mine waste failures have taken many lives, destroyed many homes and have had many other negative impacts on the public and on mining companies. Laws passed after the 1966 Aberfan tragedy, which resulted in a loss of 144 lives, forced mining companies to reduce the risk involved in mine waste practice by making it illegal for mine waste dumps to fail. Since then, there

Oct 11, 2014 This paper provides an overview of coal waste management practices with two case studies and an estimate of management cost in 2010 US dollars. Processing of as-mined coal typically results in considerable amount of coarse and fine coal processing wastes because of in-seam and out-of-seam dilution mining. Processing plant clean coal recovery values run typically 50 80 .
