Burden given Spacing for Multiple Simultaneous Blasting Solution

STEP 0: Pre-Calculation Summary

Formula Used

Burden = (Blasting Space)^2/Length of Borehole
B = (S_b)^2/L
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.
Blasting Space - (Measured in Meter) - Blasting Space denotes the lateral distance on centers between holes in a row.
Length of Borehole - (Measured in Meter) - Length of Borehole is the longer dimension of the borehole.

STEP 1: Convert Input(s) to Base Unit

Blasting Space: 16 Foot --> 4.87680000001951 Meter (Check conversion here)
Length of Borehole: 20.2 Foot --> 6.15696000002463 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

B = (S_b)^2/L --> (4.87680000001951)^2/6.15696000002463

Evaluating ... ...

B = 3.86281188120357

STEP 3: Convert Result to Output's Unit

3.86281188120357 Meter -->12.6732673267327 Foot (Check conversion here)

FINAL ANSWER

12.6732673267327 ≈ 12.67327 Foot <-- Burden

Frequency of Vibration given Acceleration of Particles

LaTeX Go Frequency of Vibration = sqrt(Acceleration of Particles/(4*(pi)^2*Amplitude of Vibration))

Amplitude of Vibrations using Velocity of Particle

LaTeX Go Amplitude of Vibration = (Velocity of Particle/(2*pi*Frequency of Vibration))

Frequency of Vibration given Velocity of Particle

LaTeX Go Frequency of Vibration = (Velocity of Particle/(2*pi*Amplitude of Vibration))

Frequency of Vibrations caused by Blasting

LaTeX Go Frequency of Vibration = (Velocity of Vibration/Wavelength of Vibration)

Burden given Spacing for Multiple Simultaneous Blasting Formula

LaTeX Go

Burden = (Blasting Space)^2/Length of Borehole
