Surface/open cast mining and deep underground mining are considered two basic methods for coal extraction globally. The rising trend of coal mining activities has resulted in the accumulation of mining and processing wastes with low carbon levels over the past few decades [6]. Fig. 1 presents different life cycle stages of coal with details of wastes generated at each stage.
34. Conversion Approaches 1. Direct Liquefaction: • Dissolves coal in a solvent at elevated temperature and pressure • Combined with hydrogen gas and a catalyst 2. Indirect Liquefaction: • Involves first gasifying coal, followed by reacting carbon monoxide and hydrogen together nCO + (2n+1)H2 = CnH2n+2 + nH2O.
Research on chemical or biological mining of coal must also include evaluations of environmental risks posed by reagents and process intermediates. Improved Machine Performance Mining depends heavily on mechanical, motordriven machinery for almost every aspect of the process, from initial extraction to transport to processing.
It is significant to note that, among the various types of mining, openpit coal mining is one of the most destructive activities in terms of its impact on the surface landscape and the ...
