Length of Borehole using Burden Solution

STEP 0: Pre-Calculation Summary

Formula Used

Length of Borehole = (Burden)^2/Diameter of Borehole
L = (B)^2/D_h
This formula uses 3 Variables

Variables Used

Length of Borehole - (Measured in Meter) - Length of Borehole is the longer dimension of the borehole.
Burden - (Measured in Meter) - Burden is the distance from the blast hole to the nearest perpendicular free face.
Diameter of Borehole - (Measured in Meter) - Diameter of Borehole is any straight-line segment that passes through the center of the borehole.

STEP 1: Convert Input(s) to Base Unit

Burden: 14 Foot --> 4.26720000001707 Meter (Check conversion here)
Diameter of Borehole: 10.1 Foot --> 3.07848000001231 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L = (B)^2/D_h --> (4.26720000001707)^2/3.07848000001231

Evaluating ... ...

L = 5.91493069309298

STEP 3: Convert Result to Output's Unit

5.91493069309298 Meter -->19.4059405940594 Foot (Check conversion here)

FINAL ANSWER

19.4059405940594 ≈ 19.40594 Foot <-- Length of Borehole
