Objective The research will involve one or two long-term measuring operations in production districts prone to rockbursts, using the MESAS seismoacoustic equipment and the PATE equipment for recording seismic seam reactions during test drilling in the same districts. The aim is to test the practical use of the methods, using the directly available results from the MESAS and PATE equipment.The aims of seismoacoustic and seismic seam reaction measurements can be summarised as follows:- objective recording of seam reactions during test drilling to improve the value of test drilling results- continuous monitoring of production districts prone to rockbursts with transmission of data to the surface, direct evaluation and up-to-date output of results- combined evaluation of seismoacoustic and operational data to reduce the number of non-critical test drilling operations and concentrate test drilling in endangered areas- fundamental studies using the data obtained for further improvement of measuring and evaluation processes and research into strata mechanics in areas prone to rockbursts (e.g. conditions favouring rockbursts)- trial and practical use of seismoacoustic procedures to supplement operational measures aimed at improving economy and safety in areas prone to rock bursts.The planned measuring of seismic seam reactions during test drilling in the same production district as seismoacoustic measurements offers scientific and economic advantages:- The comparison with operational data necessary to permit interpretation of seismoacoustic data can include the objectively recorded seismic seam reactions.- It is possible to correlate all the data from both seam reaction measurements during test drilling and seismoacoustic measurements.- Carrying out both measuring operations in the same production districts means that the cost is much lower than when different districts are involved.Overall, spot seam reaction measurements during test drilling and large-scale seismoacoustic measurements can help to achieve more economical and reliable monitoring of areas prone to rockbursts. The technical preconditions for measurements are largely fulfilled. The main objective of this research is to carry out series of measurements to ensure that the system is suitable for industrial use and above all to develop the assessment of criteria and undertake operational integration trials.
