Development of a new model for predicting flyrock distance

For this purpose, six granite quarry mines in the Johor area of Malaysia were investigated, for which various controllable blasting parameters were recorded. A total of 262 datasets consisting of six variables (i.e., powder factor, stemming length, burden-to-spacing ratio, blast-hole diameter, maximum charge per delay, and blast-hole depth) were collected applied to developing the flyrock predictive model.

Quarrying Process And Quarry Products

A stone quarry typically produces the following products: Large size blocks blasted from the quarry face, from approximately 0.5 m 3 (approximately 0.36 tonne weight) to 1.25 m 3 (approximately 5-6 tonne weight), are called rip rap or rock armour and are used in coastal and river flood defence schemes to shore up sea fronts and river banks.

Fatal Accidents Due To Flyrock And Lack Of Blast Area

lack of blast area security accounted for 68% of the injuries [Verakis and Lobb, 2001]. Miners and personnel employed by the mining industry still continue to suffer fatal and disabling injuries from blasting accidents. Blasting generally has two purposes: rock fragmentation, and displacement of the broken rock.
