This report describes the results of a system study of factors influencing mine rescue attempts based on the use of electromagnetic vf (voice frequency) rescue transmitters by trapped miners and helicopter-borne search receivers by mine rescue personnel. The report covers four areas: (1) mine emergency and disaster considerations that concentrate on characterizing the events and key parameters of mine fires and explosions related to trapped miner location and rescue activities, (2) hardware considerations that concentrate on characterizing the relevant properties of vf rescue transmitters and search receivers; oxygen-type self-rescuers; and helicopter performance, signal detectability, and sensor sweepwidths, (3) a search theory probabilistic model that develops a method to identify the most important regions to be searched and to allocate helicopter-based search efforts to maximize the number of miners detected in time to be rescued, and (4) sensitivity analyses and application of the search model on representative mine emergency and disaster scenarios to assess the impact and effectiveness of helicopter-based searches. Conclusions and recommendations are presented, together with a set of search planning guidelines.
