Description |
Blast performance depends on geo-mechanical properties of rock, detonation properties of explosive
systems and blast design parameters. For a mine having nearly constant geo-mechanical parameters and
have fixed optimized blast pattern, the blast results are very much dependent on the quality of explosive
products. For consistent blast results, quality of explosive should be consistent. Mine management needs
to ensure that performance and quality of an explosive system are the same as that has been predicated
or stated by the supplier. Periodic check of the quality and performance parameters of the explosives and
accessories of different manufacturers collected from the users’ magazines/blasting face serve as a useful
mechanism towards ensuring safety and quality of such products. In this paper, quality evaluation of slurry
and emulsion permitted explosives and permitted detonators of different firms supplied in SCCL were
done at SCCL site and their impact on performances in underground coal mines were observed. Results of
studies on post detonation toxic fumes were also done with the help of Rescue team of SCCL in presence
of CIMFR Scientist which gives the real picture of toxic contents of explosives used in underground coal
mines where working personals are allowed to work after 5 minutes of blasting. Deviations in the quality
of explosive and detonator parameters were found which has direct impact on the underground coal
production in SCCL mines. Based on the results of studies and CIMFR advice, explosive manufacturers
improved the quality of their explosive products time to time aimed for getting desired coal production
safely underground coal mines of SCCL in India
