Limestone quarries. Limestone is often produced using opencast mining methods through a multiple bench system, although excavated quarries can also be found via underground mining. Typical operations include drilling and blasting, both designed with a specific fragmentation curve in accordance with the final product to be achieved.

Boral’s Limestone Mine near Marulan in southern New South Wales is the source of limestone for up to 60 per cent of all cement products used in the state. It has operated since the 1830s, and today it is Boral’s largest mining operation in Australia. The mine blasts 3.5 million tonnes of rock a year using modern open-cut hard rock drill and

Rock fragmentation due to blasting depends upon many parameters. The properties of the explosive are one of them. In limestone quarries, ammonium nitrate–fuel oil (ANFO) or site mixed emulsion (SME) are generally used for rock fragmentation. Both these explosives cause substantial changes in the breakage mechanism of rockmass thereby affecting the fragmentation. This paper reports the effect

Abstract This paper describes the development of statistical models for assessing the boulder count resulting from the limestone quarry blasting. A database of three hundred blasts was created for the development of the model. The database consists of number of holes per row, number of rows, average spacing, average burden, average depth, average stemming, explosive type, total charge fired in
