Technological advancements in electronic sensors and minewide monitoring systems have improved remote monitoring and analysis of underground mining information. The effective use of these systems for ground control applications, however, remains a challenge facing the mining industry. The U.S. Bureau of Mines is conducting research, utilizing real-time acquisition of rock mechanics data, to provide mine operators the means to rapidly identify and manage potentially hazardous ground conditions. The Bureau has installed a remote monitoring network in a Colorado coal mine to record pressures from instruments installed in the roof and pillars of gateroads and from transducers on shield legs along the face. The field data are being monitored at the Bureau's Denver Research Center, 150 miles from the mine. A computer at the center analyzes the field data and generates graphic displays, which permit detailed examination of minewide ground conditions in real time. For the first time, Bureau researchers are able to perform real-time monitoring and analysis of rock mechanics data while mining is in progress. The data collection and display capabilities of the system were effectively used to identify and evaluate face stability problems at the mine.
