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

d. Blasting. This method is employed for quarrying hard and compact stones. The various stages involved in the method of quarrying by blasting are as follows: Boring hole in the rock. The holes are usually made (of desired depth, from 1.25 to 2.5 m deep, and 20 to 40 mm diameter) with a steel bar with knife-edged ends called jumper.

This becomes especially important when blasting method has to be used for quarrying of stones. (iii) Distance from main roads: Stones extracted from a quarry have to be transported to the nearby towns and cities. Naturally, the quarry must be located near to the main network of roads leading to those towns and cities.

Typical Method in Open Pit Quarries: A quarry rotary air drill is used to find either the top (hanging wall) or bottom (foot wall) of the deposit between core holes. Samples are taken at intervals necessary to locate the quality by simply blowing out the chips at specific intervals and placing them in sample bags for testing.

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.
