Real-time monitoring of field measurements for mine design: Greens Creek Mine, Admiralty Island, Alaska.
Spokane, WA: U.S. Department of the Interior, Bureau of Mines, RI 9613, 1995 Dec; :1-19
Field investigations were conducted at the Greens Creek Mine on Admiralty Island in southeast Alaska to validate computer design of mining methods and assessing real time monitoring capabilities. The mine used cut and fill, drift and fill, and room and pillar mining methods to mine a high grade sulfide deposit containing silver, gold, lead, zinc and copper. The site was remote, and there was a need for timely acquisition of data, and a limited budget for instruments and data acquisition. Various sensors were placed to monitor rock mass deformation and strain temperature, sulfur-dioxide (7446095) gas emissions, and blasting. A distributive personal computer network and high speed modems were used to collect the data. The 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. The results of the field tests indicated that it is possible to gather, process, visualize and verify mine designs on a real time basis.
