• Description:
  This report covers three separate areas of abandoned mine subsidence abatement technology. The first is the development of a cost effective method of remote placement of point support columns in abandoned mines through boreholes. The second is the design and test of a twin screw pneumatic pipefeeder for metering fill material into a pipeline for stowing in abandoned mine entries. The third area is a demonstration task to fill an abandoned mine tunnel using the high-efficiency pneumatic ejector and the pneumatic pipefeeder. [Description provided by NIOSH]
