Charge masses and buried depths of explosives.

Firing order	Charge mass W (kg)	Charge radius (m)	Burial depth h (m)	Scaled depth h/W^1/3 (m⋅kg^−1/3)
First explosion	0.0250	0.0221	0.500	1.71
Second explosion	0.0394	0.0277	0.582	1.71
Third explosion	0.0649	0.0356	0.687	1.71
Fourth explosion	0.1182	0.0481	0.839	1.71
