Protesters opposed to mountaintop removal coal mining shut down operations at a controversial West Virginia strip mine over the weekend with a series of coordinated lock downs, tree-sits and banner drops. Police said about 20 activists were arrested after the action Saturday at Patriot Coal’s Hobet strip mine in Lincoln County, West Virginia; most of them charged with trespassing. Activists with the group RAMPS, or Radical Action for Mountain Peoples’ Survival, criticized the Obama administration’s regulatory policies and said mining practices are endangering the health and safety of people in Appalachia.
