Room and pillar mining accounts for approximately 73 percent of the active gobs used in the United States in 1993. The Mine Safety and Health Administration conducted field investigations on six different types of bleeder systems used to ventilate areas mined by room and pillar methods. This paper discusses investigations that were conducted at mines using four of these systems.
