In a VCR stope, blast holes of 165 mm diameter are drilled. For the blast hole to behave as a spherical charge, the maximum charge length, in m, is ______. (round off up to 2 decimals)
Understand the Problem
The question is asking for the maximum charge length in a blast hole with specific dimensions. It requires an understanding of blasting operations in mining engineering.
Answer
0.165
The maximum charge length for the spherical charge to behave as intended is approximately 0.165 m.
Answer for screen readers
The maximum charge length for the spherical charge to behave as intended is approximately 0.165 m.
More Information
For the blast hole to behave like a spherical charge, the length should correspond to its diameter to maintain symmetry.
Tips
Ensure that the calculations maintain a spherical shape assumption by equating length with diameter.
