Weight Strength of Explosive using Burden Suggested in Langefors' Formula Solution

STEP 0: Pre-Calculation Summary
Formula Used
Weight Strength of Explosive = (33*Burden in Langefors' Formula/Diameter of Drill Bit)^2*((Ratio of Spacing to Burden*Rock Constant*Degree of Fraction)/Degree of Packing)
s = (33*BL/db)^2*((EV*c*Df)/Dp)
This formula uses 7 Variables
Variables Used
Weight Strength of Explosive - Weight Strength of Explosive the measure the absolute amount of energy available in each gram of explosive.
Burden in Langefors' Formula - (Measured in Millimeter) - Burden in Langefors' Formula is the ratio of explosive weight to rock mass, determining efficient rock fragmentation in blasting operations.
Diameter of Drill Bit - (Measured in Millimeter) - Diameter of Drill Bit in Langefors’ Formula relates rock drillability to bit diameter, expressing the effect of diameter on drilling efficiency and performance.
Ratio of Spacing to Burden - Ratio of Spacing to Burden is the relationship between the gap size and load-carrying capacity in structural elements.
Rock Constant - Rock Constant is a fundamental geological parameter representing Earth's average continental crust composition, vital for understanding planetary evolution and geodynamics.
Degree of Fraction - Degree of Fraction is used for hole characteristics.
Degree of Packing - (Measured in Kilogram per Cubic Decimeter) - Degree of Packing is the loading weight per unit of nominal volume.
STEP 1: Convert Input(s) to Base Unit
Burden in Langefors' Formula: 0.01 Meter --> 10 Millimeter (Check conversion ​here)
Diameter of Drill Bit: 97.5 Millimeter --> 97.5 Millimeter No Conversion Required
Ratio of Spacing to Burden: 0.5 --> No Conversion Required
Rock Constant: 1.3 --> No Conversion Required
Degree of Fraction: 2.03 --> No Conversion Required
Degree of Packing: 3.01 Kilogram per Cubic Decimeter --> 3.01 Kilogram per Cubic Decimeter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
s = (33*BL/db)^2*((EV*c*Df)/Dp) --> (33*10/97.5)^2*((0.5*1.3*2.03)/3.01)
Evaluating ... ...
s = 5.02182468694097
STEP 3: Convert Result to Output's Unit
5.02182468694097 --> No Conversion Required
FINAL ANSWER
5.02182468694097 5.021825 <-- Weight Strength of Explosive
