The Bureau of Mines' Spokane Mining Research Center is evaluating the use of earth satellite technology and aerial photography techniques to monitor the safety of coal waste embankments and impoundments. The research projects evolved because of the present and future abundance of waste embankments and impoundments and the difficulty associated with evaluating their stability and safety. When making stability determinations, many qualitative and quantitative factors must be considered. Some of the more important stability determination factors are shown in Table 10 Physical property data must be developed either from field sampling and laboratory testing or from estimate extracted from soil mechanics tables. Other quantitative information can be obtained from field measurements, in situ instrumentation, and remote sensing. Qualitative data can be obtained from onsite visual inspections or remote sensing. This paper includes past, ongoing, and planned research for two novel monitoring projects which, if successfully developed, will yield fast, reliable, and accurate embankment performance (stability, environmental, etc.) information. Final feasibility of the two techniques is under evaluation. However, preliminary results and cost data are available, and final results will be reported as the projects are concluded.
