## Description

Developed in accordance with GB 6722-2014 Blasting Safety Regulations.
Perform accurate vibration-safety distance calculations anytime — fully offline.

This application is developed in accordance with the National Standard of the People’s Republic of China — GB 6722-2014 “Blasting Safety Regulations”,
and is designed to calculate the allowable safety distance of blasting vibration.

Required Parameters:
	•	K, α (Coefficient and Attenuation Index):
Represent the influence of geological and topographical conditions between the blasting site and the protected object, determined through field tests.
	•	V (Allowable Particle Velocity):
The maximum particle velocity that the protected object can safely withstand at its location, measured in cm/s.
	•	Q (Charge Weight of Explosives):
The total explosive charge used for blasting; for delayed blasting, the largest single segment charge should be used, measured in kilograms (kg).

Calculation Result:
	•	R (Allowable Safety Distance):
The minimum safe distance (in meters) ensuring that vibration from blasting does not exceed the allowable level for the protected object.

Formula:
R = (K / V)^(1/α) × Q^(1/3)

This formula is widely applied in mining, tunneling, and construction blasting safety analysis to evaluate the potential impact of blasting vibrations on nearby structures and facilities.
