Sweden where Bulk Emulsion Explosives have been used. 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.
Are civil and military explosives the same? In other words, are we using the same explosives in mining and warfare? Well, yes and no. From the ninth century AD (though the historians are still uncertain about the exact date of its invention) to the mid1800s, black powder was the only explosive available.

It has already enabled safer work methods and mining techniques that increase recovery, productivity and efficiency, according to the company. It concluded: "Many technical and regulatory challenges will be faced by wireless blasting, but it is a fundamental step in the automation of the explosives charging and blasting process.
Controlling the Adverse Effects of Blasting This module addresses the control of offsite impacts that result from blasting, namely: • vibrations, • airblast, and • flyrock. Much of the information in the module is derived from the Surface Mining Control and Reclamation Act of 1977 (SMCRA). The performance standards apply to all
General guidelines of Charging and Blasting in Hot Strata condition: Select the number of holes properly so that the total blasting operation should not exceed 2 hour from charging of first hole. Measure the temperature of the holes almost constantly till the commencement of blasting operation.
