Abstract
A coal-rock interface detector (cid) system is of major importance in providing coal-seam-tracking capability for mining machines. The cid system must be capable of measuring one or more properties of coal and adjacent formations. Subsequently, it must be able to identify the geologic material being cut, locate the coal-rock interface, and/or determine the thickness of the coal remaining below the roof or above the floor. This paper provides a brief practical overview of various types of commercial and experimental cid systems currently being used and novel cid concepts being investigated by the Bureau and other research organizations throughout the world. In addition, two systems designed for noncoal operations are identified.
