Abstract
A data acquisition and monitoring system developed, packaged, and field-tested by the U.S. Bureau of Mines for a deep mine shaft is described. This system provides process information to mine supervisors and shaft operators. An in-mine sensor package monitors the rock mass and support in deep mine hoisting operations. The sensors are based on linear and rotary potentiometers, platinum resistance temperature detectors, strain gauge load cells, and quarter-bridge strain circuitry. Data are acquired through a distributed network of intelligent measurement pods connected to an interface card and a personal computer (PC). The system scans the sensors at a predetermined rate (up to 600 scans per second) and provides real-time trend plots, process graphics, and a spreadsheet of the current data set. Data are transmitted via short- and long- haul modems to PC's for detailed analysis and plotting. The system is low cost, efficient, and reliable, and it is currently being integrated with shaft ore handling and hoisting process sensing, supervision, and control.
