One, for the measurement of temperature and two, for the measurement of displacement of rock mass which may be useful for the remote monitoring of strata movement above a longwall coal mine, collapse of a longwall panel, opencast mine, mine subsidence and underground nuclear tests. Optical fiber, being a dielectric, non-metallic, non-sparking, free from electromagnetic and radio frequency interferences is an intrinsically safe media and is ideally suited to the hazardous environment present in mines.
