A Method of Calculating Critical Depth of Burial of Explosive Charges to Generate Bulging and Cratering in Rock

Table 1

Calculated results: two types of critical depth of burial.

Dimensionless impact factor	795.942	955.130	1193.913	1591.884	2387.825
FCDOB (m/kg^1/3)	0.844	0.914	1.004	1.142	1.365
SCDOB (m/kg^1/3)	0.540	0.570	0.610	0.667	0.757
RCDOB	1.563	1.604	1.645	1.712	1.803

FCDOB denotes the “first critical depth of burial.”
SCDOB denotes the “second critical depth of burial.”
RCDOB denotes the “ratio of first critical depth of burial to second critical depth of burial.”
