Burden given Stemming at Top of Borehole Solution

STEP 0: Pre-Calculation Summary

Formula Used

Burden = (Stemming at Top of Borehole-(Overburden/2))/0.7
B = (S-(OB/2))/0.7
This formula uses 3 Variables

Variables Used

Burden - (Measured in Meter) - Burden is the distance from the blast hole to the nearest perpendicular free face.
Stemming at Top of Borehole - (Measured in Meter) - Stemming at Top of Borehole involves preventing soil or fluid influx during drilling operations to maintain stability.
Overburden - (Measured in Meter) - Overburden is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem.

STEP 1: Convert Input(s) to Base Unit

Stemming at Top of Borehole: 11.3 Foot --> 3.44424000001378 Meter (Check conversion here)
Overburden: 3.02 Foot --> 0.920496000003682 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

B = (S-(OB/2))/0.7 --> (3.44424000001378-(0.920496000003682/2))/0.7

Evaluating ... ...

B = 4.26284571430277

STEP 3: Convert Result to Output's Unit

4.26284571430277 Meter -->13.9857142857143 Foot (Check conversion here)

FINAL ANSWER

13.9857142857143 ≈ 13.98571 Foot <-- Burden
