cost benefit analysis coal mine waste piles

In December 2010 environmentalists stated that the EPA's report on costbenefit analysis of coal ash waste was riddled with errors As a result, environmentalists stated that they fear that the EPA's analysis would lead to less stringent standards for the substance, a move they said would disregard the potential health effects of coalash exposure

Reduction and utilization of coal mine waste rock in

2014-2-1  In China, coal mine waste rock (CMWR) produced in coal mining and processing is the greatest source of industrial solid waste in terms of production, accumulation volume, and occupied area. There are about 4.5 billion tons of CMWR stockpiled into more than 1700 waste dumps which occupied 150 km 2 of land (Bian et al., 2009, Zhao et al., 2008).
