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

< 17 Parameters of Vibration Control in Blasting Calculators

Burden Suggested in Langefors' Formula

Go Burden in Langefors' Formula = (Diameter of Drill Bit/33)*sqrt((Degree of Packing*Weight Strength of Explosive)/(Rock Constant*Degree of Fraction*Ratio of Spacing to Burden))

Frequency of Vibration given Acceleration of Particles

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

Burden Suggested in Konya Formula

Go Burden = (3.15*Diameter of Explosive)*(Specific Gravity of Explosive/Specific Gravity of Rock)^(1/3)

Amplitude of Vibrations given Acceleration of Particles

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

Distance from Explosion to Exposure given Overpressure

Go Distance from Explosion to Exposure = ((226.62/Overpressure))^(1/1.407)*(Maximum Weight of Explosives per Delay)^(1/3)

Overpressure due to Charge Exploded on Ground Surface

Go Overpressure = 226.62*((Maximum Weight of Explosives per Delay)^(1/3)/Distance from Explosion to Exposure)^(1.407)

Amplitude of Vibrations using Velocity of Particle

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

Frequency of Vibration given Velocity of Particle

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

Frequency of Vibrations caused by Blasting

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

Burden given Stemming at Top of Borehole

Go Burden = (Stemming at Top of Borehole-(Overburden/2))/0.7

Diameter of Borehole using Burden

Go Diameter of Borehole = (Burden)^2/Length of Borehole

Length of Borehole using Burden

Go Length of Borehole = (Burden)^2/Diameter of Borehole

Length of Borehole given Spacing for Multiple Simultaneous Blasting

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

Burden given Spacing for Multiple Simultaneous Blasting

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

Overpressure given Sound Pressure Level in Decibels

Go Overpressure = (Sound Pressure Level)^(1/0.084)*(6.95*10^(-28))

Minimum Length of Borehole in Meter

Go Length of Borehole = (2*25.4*Diameter of Bore Pith Circle)

Minimum Length of Borehole in Feet

Go Length of Borehole = (2*Diameter of Borehole)

Burden given Stemming at Top of Borehole Formula

Burden = (Stemming at Top of Borehole-(Overburden/2))/0.7
B = (S-(OB/2))/0.7
