Abstract
RIM-IV technology is the most promising geophysical method to identify and locate geological anomalies in advance of mining. In order to make this technology successful, ground-truth works are needed to explore its potentials and limitations in application. Two cases in which the RIM-IV technology has been applied to detecting various geological anomalies have been presented in this research. In the first case, the RIM-IV survey was conducted in a section of the longwall panel where sandstone intrusions, seam thinning and severe seam undulations were expected. In the second case, the RIM-IV survey was performed in a section of the longwall panel where a fault was anticipated. In addition to the fault, high sulfur and ash contents also showed in the survey area. For the purpose of ground-truth, geological data have been collected in and around the survey areas. Statistical analyses have been used to correlate the different factors of the identified geological anomalies with the reconstructed tomograms of electromagnetic attenuation rate. Such analyses enabled quantifying the applicability of the RIM-IV technology.
