To date in the literature, there have not been sufficient LCA analyses of mine processes. It is worth emphasising that this paper is the first to present a computational LCA model for calculating the environmental life cycle assessment for the identified coal mining processes that shows the results of LCA for coal mining operations in Poland.

The time period and location can also have a significant effect on the how the prototype did it and what a model might look like and what the coal coming out of the mine looked like as well. In days of hand mining the size of coal was important and mining was designed to get the largest sized of coal that could be manually handled.
Coal "mines" somewhat depend on the region of the country. In Appalachia, the railroad connection could be anything from a processing plant on the large scale to a small mine or just a loader where dump trucks bring their coal for transfer to the railroad.
