Abstract
Description
Underground excavation processes in mining enterprises are a very dangerous environment and process. Geological and is one of the factors affecting the excavation condition in geotechnological condition. Mines during the mining process a methodological approach and a well-planned risk response. This article will be discussed in mining enterprises in geotechnological methods that approach to identify and understand the hazard that occurs underground the classification of excavation processes is given. Geotechnical risk must be recognized before, during and after excavation. The author explained with examples how to use drilling data, seismic data and ground motion indicator to identify geotechnological hazard. From the drilling data, the drill core is determined using the Geological Strength Index. In mining enterprises combined with several studies as a test to determine the place and condition of the geological and geotechnological location of the mine before excavation. Seismic the device indicates the location of the mine from the processes of excavation blasting or mining. Tunnel transformation is monitored using a ground motion indicator device to determine geotechnical and remedial measures are considered after excavation. Finally, geotechnical data analysis is performed to reduce the risk and plans are made to ensure economic or safe operation, as well as time to meet the impending geotechnical hazard, ensuring the safe operation of the process during that time.
