For free running explosives, the density is often specified as the pounds of explosives per foot of charge length in a given size borehole.

With few exceptions, denser explosives give higher detonation velocities and pressures. Density is an important consideration when choosing an explosive. Instead, secondary explosives are detonated using a primary explosive (e.g., a blasting cap) to start the reaction.

Dynamite is an example of a secondary explosive. Another tier of explosives, tertiary explosives (or blasting agents), require the detonation of a primary explosive, followed by a secondary explosive to ignite%(5).

Military uses of explosives are legion. In civil projects, they are utilized for fragmentation or displacement of geologic materials in surface, underground, and underwater construction (Langefors and Kihlstrom, ); in quarrying and mining (Lewis Comparative Studies of Explosives in Limestone.

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO.

Initial sample temperatures ranged from to K. Sustained-shock experiments showed a strong initial temperature effect.

Except for very deep-seated deposits, open cast mining method has been recognized as the safest and most productive mode for mining minerals. Ever growing demand in minerals and coal has compelled the mine operators to increase the size of mine, which has resulted in an increasing trend towards large capacity open cast projects.
