| Review: |
Coal mining causes a number of problems: the pile up of waste materials may become unstable, and the waste materials that accumulate must be disposed of somewhere. Attention has been focused on minimizing the accumulate of waste materials by using them as a secondary aggregate or other raw material, or by recovering the coal in a way that lead to less waste. This book begins by looking at the factors that cause detrimental effects to the atmosphere from coal mining and processing. It goes on to look at anti-pollution measures for water in mines; the composition and properties of the residual solid waste from coal mines; ways of using the solid wastes from coal mines; and assessing the quantities of hazardous compounds formed from trace elements contained in coals. |
