Abandoned Mines Lands

Abandoned mine land (AML) features represent a legacy of mineral extraction within the national parks. Management of these areas poses unique challenges since many abandoned mines are cultural resources that represent the history of local mining and also provide habitat for threatened and endangered species.

Inclined shafts driven in the coal were used when the dip of the beds would permit. Vertical shafts were used when the coal was deep. Many of the early mines had only one entry/exit point. Vertical shafts frequently used a furnace at the bottom of the shaft to create a flow of air to ventilate the mine.

Using tunnel boring machine (TBM) to construct inclined shafts in coal mines has become the main way for large-scale coal mines to enter deep mining faces. However, some engineering disasters such as water in rush and rock burst will occur when TBM crosses the aquifer and weak broken rock strata.
