Improved Coal Interface Detector
This report describes the theory, design, construction and testing of an electromagnetic coal interface detector. The purpose of this type detector is measuring the thickness of roof coal left during underground mining operations. An above ground test facility constructed to evaluate the coal interface detector is also described.
