Overburden given Stemming at Top of Borehole Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
Burden - (Measured in Meter) - Burden is the distance from the blast hole to the nearest perpendicular free face.

STEP 1: Convert Input(s) to Base Unit

Stemming at Top of Borehole: 11.3 Foot --> 3.44424000001378 Meter (Check conversion here)
Burden: 14 Foot --> 4.26720000001707 Meter (Check conversion here)

Diameter of Drill Bit using Burden Suggested in Langefors' Formula

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

Weight Strength of Explosive using Burden Suggested in Langefors' Formula

Go 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)

Maximum Weight of Explosives given Scaled Distance for Vibration Control

Go Maximum Weight of Explosives per Delay = ((Distance from Explosion to Exposure)^(-Constant of Scaled Distance β)*(Constant of Scaled Distance/Scaled Distance))^(-2/Constant of Scaled Distance β)

Distance to Exposure given Scaled Distance for Vibration Control

Go Distance from Explosion to Exposure = sqrt(Maximum Weight of Explosives per Delay)*(Scaled Distance/Constant of Scaled Distance)^(-1/Constant of Scaled Distance β)

Scaled Distance for Vibration Control

Go Scaled Distance = Constant of Scaled Distance*(Distance from Explosion to Exposure/sqrt(Maximum Weight of Explosives per Delay))^(-Constant of Scaled Distance β)

Distance of Particle Two from Site of Explosion given Velocity

Go Distance of Particle 2 from Explosion = Distance of Particle 1 from Explosion*(Velocity of Particle with Mass m1/Velocity of Particle with Mass m2)^(2/3)

Velocity of Particle One at Distance from Explosion

Go Velocity of Particle with Mass m1 = Velocity of Particle with Mass m2*(Distance of Particle 2 from Explosion/Distance of Particle 1 from Explosion)^(1.5)

Velocity of Particle Two at distance from Explosion

Go Velocity of Particle with Mass m2 = Velocity of Particle with Mass m1*(Distance of Particle 1 from Explosion/Distance of Particle 2 from Explosion)^(1.5)

Distance of Particle One from Site of Explosion

Go Distance of Particle 1 from Explosion = Distance of Particle 2 from Explosion*(Velocity of Particle with Mass m2/Velocity of Particle with Mass m1)^(2/3)

Diameter of Explosive using Burden Suggested in Konya Formula

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

Specific Gravity of Explosive using Burden Suggested in Konya Formula

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

Specific Gravity of Rock using Burden Suggested in Konya Formula

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

Acceleration of Particles disturbed by Vibrations

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

Velocity of Particles disturbed by Vibrations

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

Distance from Blast Hole to Nearest Perpendicular Free Face or Burden

Go Burden = sqrt(Diameter of Borehole*Length of Borehole)

Spacing for Multiple Simultaneous Blasting

Go Blasting Space = sqrt(Burden*Length of Borehole)

Wavelength of Vibrations caused by Blasting

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

Velocity of Vibrations caused by Blasting

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

Stemming at Top of Borehole to Prevent Explosive Gases from Escaping

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

Overburden given Stemming at Top of Borehole

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