Applying LCI figures from coal mining, cleaning, transportation and burning processes into Gabi 4, we can get main waste gas emissions in Electricity Coal Supply Chain, which is shown in Table 4 (Wang and Mu 2012). The result of coal-cleaning process is merged into coal-mining process in this table.

In fact, the lack of LCI data on coal mining has been cited as one of hindrances to the accuracy of LCI data. A search on the International Journal of Life Cycle assessment gives only 23 results with "coal mining" which reflects the relatively low application of LCA studies in coal mining or even in mining industry. ...

Extensive LCA work has been done on coal use, particularly in electricity generation, but, the coal mining stage has been neglected, for the most part. This has resulted in data gaps in the life cycle inventory (LCI) of coal and, consequently, in the LCIs for electricity and other products that are linked to coal.
