Investigations Investigations

A highly productive method, longwall mining yielded 176 million tons of coal in 2007 — 15 percent of total U.S. production. An estimated 10 percent of all U.S. electricity now depends on coal from longwall mines, which have grown in Appalachia and in Illinois, Utah, Colorado, and New Mexico. But longwall mining is the most brutal technology yet employed to extract coal from underground quickly and cheaply. This project examines social and environmental impacts of longwall’s full-extraction method.

Key Findings:

  • Structures above a longwall mine almost always suffer subsidence, forcing homeowners to contend with such damages as shattered foundations, crooked roofs, and cracked plaster. By last September, 1,819 property owners had reported longwall damages since the state began documenting such complaints.
  • Longwall mining dams, diminishes, and dries up water sources. Scientists have found the practice is permanently lowering the area’s water table and draining its aquifers; state regulators have reported damages to 23 stretches over 97 miles of mined streams.
  • The environmental fallout has hit farmers so hard that the agricultural land and farming community are dwindling.
  • State policymakers have fostered this destruction through the mining law and environmental regulations, leaving citizens virtually powerless to undo harm.
