||Geologists can use three-dimensional visualization in order to better predict roof and floor conditions in advance of underground mining in the vicinity of the Galatia Channel. Unknown or unstable roof and floor conditions in an underground mine can lead to mining accidents.
||The goal of this project is to predict roof and floor conditions in advance of mining.
||The project utilized 3-D software to help visualize roof facies in an underground coal mine. Detailed descriptions of core were combined with facies analysis of gamma-ray logs to produce facies maps. The approach is unique in that it involves attempting to model the Dykersburg "grey shale wedge" as an incised valley, a new approach, in an effort to discover if more predictable facies models can be generated.
||This project will result in detailed facies maps of mined-out areas and areas close to advancing mine walls. A new predictive model to facilitate mine planning will be produced.
||The use of facies maps and 3-D visualizations can reduce the risk to miners and mining operations and will facilitate planning for future mining.
