Blasting is the most cost-effective way to fracture rock so that it can be excavated. Blasting lowers costs for building materials, such as sand, gravel, concrete and other products derived from rocks. Who may conduct blasting ? Only a certified blaster licensed by the State of New York may conduct blasting in New York's quarries and mines.
Blasting is one of the most feared and least understood aspects of mining operations in Ohio and elsewhere. But on a typical workday, over a quarter million pounds of explosives are safely detonated in Ohio's quarries and surface coal mines.

ment for blasting contractors to make every attempt both to adopt bulk explosives, and to persuade clients that these are ap-propriate for every kind of application. Most construction blasting requires both limiting the explo-sive mass per hole and ensuring an even breaking eﬀ ect along the blast hole.
A comparison is made with other types of explosives re garding costs for drilling and blasting. By using Bulk Emulsion Explosive it was possible to achieve a better breakage performance. In a copper mine this resulted in a decreased powder factor and thereby less cost for the explosive. In a limestone quarry
