A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. Various types are used to cut and form metal, initiate nuclear weapons, penetrate armor, and perforate wells in the oil and gas industry.. A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steel to a depth of seven or more times the diameter of the charge ...

The reader desiring additional information may refer to Gary Hemphill's book, "Blasting Operations," McGraw Hill, ISBN 0-07-028093-2 and valuable material published by the various powder companies as a service the mining industry.
The Mining Laser is a powerful high-tech tool with a variety of applications. It can be used as an insta-mining tool with a relatively low EU consumption, as well as a high-power AoE block remover, or even as a weapon. All blocks destroyed by the Laser are dropped, with the exception of non-drop blocks like Glass or Leaves.
The air gap around an explosive charge absorbs the shock energy and results in poor fragmentation. The explosive column illustrated in Figure 8-6 on the right will produce the best fragmentation. EXPLOSIVES ECONOMICS The economic analysis of the use of explosives is an important part of blasting operations in mining and construction.

Blasting ascending wells involves drilling of a fan of the ascending wells, their charge, stemming and blasting. The new method is the implementation of tamping wells in the form of monolithic rods of viscous material with a conical tubes at the ends, placed between the explosive charge in the borehole and the emphasis in development drilling.
Once you are issued an ATF permit or license, you will be legal to purchase commercially manufactured explosive materials from logging-mining supply stores from brands including Austin Powder and Dyno Nobel. The first part of an explosives sequence is the blasting cap initiator. The blasting cap detonates dynamite or other explosive materials.
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
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.
