Real-Time Monitoring of Field Measurements for Mine Design: Greens Creek Mine,Admiralty Island, Alaska

摘要

Researchers at the U.S Bureau of Mines conducted field investigations at theGreens Creek Mine in southeast Alaska for the purpose of validating computer design of mining methods and assessing real-time monitoring capabilities. The field study required the application of new technology because of the remoteness of the study site the need for timely acquisition of data, and a limited budget for instruments and data acquistion. Various sensors were installed to monitor rock mass deformation and strain, temperature, SO2 gas emissions, and blasting. Data were collected through a distributed personal computer network and high-speed modems. These readings were used to develop visualization models of underground metal mining operations and drift-and-fill mining and real-time graphics displays of ground conditions. Results of the field tests showed that it is possible to gather, process, visualize, and verify mine designs on a real-time basis.
