The onus of determining the safe distance rests on the qualified person who in most cases is the blaster. In brief the message is " Be alert and share information know the blasting time blast area and ".

Blasting Vibration Safety Criteria for Shotcrete in

 · At the same time a safe distance for shotcrete supports during tunnel blasting was determined by studying the propagation of the blasting vibration through the rock. These achievements can guide the construction of underground excavations and the design of shotcrete primary supports.

A Case Study on Safe Blast Design with Vibration Analysis

 · Safe delicacy blasting is necessarily to decrease safe problems resulting from blasting but if designs to consider only safety it is a problem not to ensure economical gains because the effect of blasting is decreased. the distance with blasting radius (m) W a charge of gunpowder per hang fires (kg) KS blasting vibration constant of

Optimized Calculation for Safe Distance of Blasting

Referring to the typical calculation equation for safe distance of blasting vibration the cause of deviation is analyzed from the parameters. It is considered that the main causes of deviation are from three aspects. ① The analogous value of K and α is not objective. ② The geological condition has been changed by on site blasting. ③ The experimentation is not representative.
