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)
