Outline
In the paper, the theoretical inter-hole delay time and theoretical delay time between rows for such three types of lithology as iron ore, dolomite and slate in firing network are calculated by averaging as well as reasonable parameters are formulated to organize and launch bursting test through analyzing domestic and foreign rock breaking theory of millisecond blasting. The study showed that the reasonable inter-hole delay time of dolomite was 32 ms and that with blast block≤800 mm accounted for 98.17%; reasonable inter-hole delay time of slate was 40 ms and that with blast block≤800 mm accounted for 91.11%; reasonable inter-hole delay time of iron ore was 28 ms and that with blast block≤600 mm accounted for 82.16%. The proportions of qualified block corresponding to reasonable delay time of each lithology are increased.
