Hestia D System
Dispatching system to support the work of mining geophysics stations Hestia D
An integrated dispatcher system designed to support the work of mining geophysics stations. The main task of the HESTIA D program is to assess the threat of rock bumps on the basis of information provided by the ARES and ARAMIS systems.
The program’s functions allow to reflect the organizational structure of the mine (seams, regions, workings) in the database. The database also stores information provided by the ARES system (hazard assessment for the workings determined by the seismoacoustic method), ARAMIS (list of recorded and localized seismic phenomena) and information entered by the user on small diameter drillings performed. On the basis of this information, HESTIA evaluates the degree of rock bump hazard using the seismological method and the method of small diameter drilling.
The program allows to generate reports on the number of seismic phenomena, their types and energies, as well as to generate a daily (shift) report on the degree of rock bounce hazard in mine workings. The assessments and reports are performed automatically and the assessment algorithms are in accordance with the current instruction of the Central Mining Institute on methods of assessing the degree of rock bump hazard using the following methods: seismoacoustics, seismology, small diameter drilling and comprehensive method.
The software allows assessment by the comprehensive method according to instructions No. 1, 20 and 22. Thanks to cooperation with the Institute of Geophysics of the Polish Academy of Sciences, the program allows, on the basis of data collected from the mine’s seismometer network(s), to determine maps of passive velocity tomography obtained using the probabilistic inversion method. The correctness of the implemented method has been repeatedly verified experimentally and in mining practice. Thanks to the new analytical functions, the employees of the mining geophysics station are provided with new tools that allow them to actively assess the current hazard.
