dc.description.abstract | Underground mining of coal seams in the Upper
Silesian Coal Basin is currently performed under difficult
geological and mining conditions. The mining depth, dislocations
(faults and folds) and mining remnants are
responsible for rockburst hazard in the highest degree. This
hazard can be minimized by using active rockburst prevention,
where destress blastings play an important role.
Destress blastings in coal seams aim to destress the local
stress concentrations. These blastings are usually performed
from the longwall face to decrease the stress level
ahead of the longwall. An accurate estimation of active
rockburst prevention effectiveness is important during
mining under disadvantageous geological and mining
conditions, which affect the risk of rockburst. Seismic
source parameters characterize the focus of tremor, which
may be useful in estimating the destress blasting effects.
Investigated destress blastings were performed in coal
seam no. 507 during its longwall mining in one of the coal
mines in the Upper Silesian Coal Basin under difficult
geological and mining conditions. The seismic source
parameters of the provoked tremors were calculated. The
presented preliminary investigations enable a rapid estimation
of the destress blasting effectiveness using seismic
source parameters, but further analysis in other geological
and mining conditions with other blasting parameters is
required. | pl_PL |
