Korelacije na izradi jamskih prostorija miniranjem pod utjecajem gorskih udara

Comprehensive testing blastings on the development faces in the areas with bursts have been performed in the coal mine of Labin. The obtained results prove distinct relations in explosive consumption (kg/m^sup 3^) and in the dimension of faces' cross-section (m^sup 2^). The impact of the work face structure (coal : stone) has been distinguished for each blasting, too. Changes depending on the brand of explosive as well as those ones considering the advance of mining activity have also been observed. It has been proved in the production 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.
