Table 2

Charge structure and initiation sequence form.

Sample number	Charge (diameter × length) (cm)	Initiation sequence	K
1	1.4 × 24	1# and 2#, 3# and 4# blast holes millisecond blasting, respectively, 5# blast hole separate initiating	1.79
2	1.4 × 24	Single order initiation 1#-2#-3#-4#-5#	2.57
3	1.4 × 24	Single order initiation 1#-2#-3#-4#-5#	3.29

Sample numbers 1#, 2#, and 3# corresponding to 9#, 11#, and 12# in literature [24].
