Abstract The U.S. Bureau of Mines and a mining company are cooperatively demonstrating the shield type roof support in the longwall mining of a 10-1/2-foot coalbed in New Mexico. As part of the demonstration, the shield supports have been successfully and safely moved from a completed longwall face to a new longwall face. When these shield supports were moved in 1976 they were the largest and heaviest longwall support system in use in United States coal mines. The shield supports, preparations for moving them, the actual move, and installation at the new face are discussed.
