Correlations on the Mining Workings Drive by Blasting Under the Impact of Rock Bursts

Vladimir Abramović

Abstract

Comprehensive testing blastings on ihe development faces in the areas with bursts have been performed in the coal mine of Labin. The obtained results prove d isti ne t relations in exp!osive consumption (kg/m3) and in the dimension of faces' cross-section (m2), The impact of the work face structure (coal: stone) bas been distinguished for each blasting, too. Chaoges depending on the brand of esplosive as well as those ones considering the advance of mining activitv have also been observed. It has been proved in the pro-duction process of the mine, that the results with increased work productivity are obtained in spite of the fact that miners are exposed to danger of rock bursts.
