Abstract : Seismic monitoring of a Comprehensive Test Ban Treaty may require the detection, location and identification of seismic events as small as mb=2.5 in limited areas. Considering the emphasis placed by the current Administration on such an agreement, it is important to assess the complexity of the proposed task. The discrimination between earthquakes, chemical mining explosions and nuclear explosions using regional seismic waves has been shown to be strongly region dependent. The establishment of a physical framework for discriminants is important if successful techniques developed in one region are to reliably transported and used in another location. Quick acquisition of region specific data, such as information related to crust and upper mantle velocity model, wave propagation characteristics and mining practices of interest, is required for practical implementation of a monitoring system. An experiment was executed during the last two weeks of August 1994 to test the applicability of such a seismic monitoring system combining near-source and regional data. It was conducted in and around an ore mine in Southern Russia. Validation of mining and blasting practices through direct field observations is identified as ground truthing. These direct observations are compared to official records of blasting practices. (AN)
