Mine Subsidence Protection Program

The Mine Subsidence Protection Program (MSPP) was established to pay for damage to Colorado homes that results from coal mine subsidence. The federal government, which shares reclamation fees levied on current coal production with the states, has given Colorado a $3 million grant to establish the Program. The money, invested in a trust fund, …

Subsidence in coal mines | PDF

Mine subsidence can be defined as movement of the ground surface as a result of readjustments of the overburden due to collapse or failure of underground mine workings. Surface subsidence features usually take the form of either sinkholes or troughs. Sinkhole subsidence is common in areas overlying shallow room-and-pillar mines.
