Method and apparatus for monitoring gateroad structural change

A method and apparatus is provided for determining structural change in a mining operation. A first scan of gateroad surfaces is obtained and information of the scan profile is stored. At a later time a second scan of the gateroad surfaces is then obtained. Information of the scans can be registered...

description A method and apparatus is provided for determining structural change in a mining operation. A first scan of gateroad surfaces is obtained and information of the scan profile is stored. At a later time a second scan of the gateroad surfaces is then obtained. Information of the scans can be registered and any difference noted. If the difference exceeds a threshold a warning can be provided indicating a gateroad structural change that may be hazardous. The scans can be made from a single sensor, or from multiple sensors (301, 303). In the case where the sensors (301, 303) are mounted on a gateroad traversing structure (109), the distance of spacing of the sensors (301, 303) can be used to determine when the sensor (303) has reached a position of movement or travel of the gateroad traversing structure (109) where the scan from sensor (301) was made. A distance sensor (309) can be provided to determine the distance of movement and where the scans coincide.
