Technical Note on The Prediction and Control of Flyrock
The control of flyrock within secured distance around the blasting site can largely be established by proper selection of various blast design parameters. Selection of proper burden plays the most crucial role as blasts with very small or very large around the surface mining site (DGMS 1982). However adoption of 500 m as the

Taking precautions against flyrock Business Queensland
Taking precautions against flyrock. Flyrock is the undesirable throw of debris from a blast. Because flyrock can cause severe injury and property damage shotfirers must take precautions to prevent it especially if blasting occurs near property or people. Nearly all previous flyrock incidents could have been avoided.

Flyrock is considered as one of the main causes of human injury fatalities and structural damage among all undesirable environmental impacts of blasting. Therefore it seems that the proper prediction/simulation of flyrock is essential especially in order to determine blast safety area. If proper control measures are taken then the flyrock distance can be controlled and in return the

Flyrock Issues In Blastingstacks.cdc.gov
The majority of blasting occurs in surface mining operations. Blasting results in the fragmentation and often the projection of rocks. Frequently the rocks are thrown beyond the expected limits. Flyrock and failure to secure the blasting area dominate blasting-related accidents in mining especially in surface mining.

Fatal Accidents Due To Flyrock And Lack Of Blast Area
Coal and nonmetal mining used about 4.3 billion pounds of explosives and blasting agents during 2001 in the United States. A major part of this consumption was related to surface mining. Mine Safety and Health Administration accident data indicate that flyrock and lack of blast area security were the primary causes of blasting-related injuries in surface mining.
