Truly energy can neither be created not be destroyed but can change from one form to another. Explosive are chemical compound which at detonation releases specific joules of energy. The energy release during Blasting travels in form of shock  wave, heat energy, light energy, sound energy and gas energy. The first release is light energy followed by shock wave which is associated with heat energy.
The last release energy is the gas energy which finalize the work need to be done by Explosive charge

Water and Mining operation: Challenge to mining efficiency

Dewatering operation is one of the most sensitive and continuous operation during raining season.
The approach to this operation depends on the mine design, mining method and other factors including the mine terrain.
Most surface mine can not escape the challenge of surface water inflow but can be overcome through proper dewatering plan.
Dewatering is define as the process of removing unwanted collection of water in the mine. It describe as the approach use in

Explosive and Blasting: How it Begins

An explosive is any chemical compound that is capable of undergoing instantaneous detonation under the supply of an impulse (high VOD shock wave) like fire, lightening, heat, friction, shock. Such compound at the point of detonation releases high energetic shock and gas energy which result into Explosion (increase in volume) under an exothermic reaction. Explosive energy can be hazardous big not properly managed. Explosives are only design for war (military) and peace (Mining) other usage (terro

Blasting optimization through pre-planning operation

Blasting operation affect both downstream operation efficiency an cost.Blasting a on of the many ways implore by mining Engineer to break rock mass into fragment via th use of Explosive.Industrial Explosive mostly used for blasting include; Nitroglycerin base dynamite (Alfro Nobel), emulsion gel base Explosive (heavy ANFO, NitroGel) and ANFO.Blasting operation is dangerous due to it associated environmental impacts like flyrock, ground vibration, airblast and Noise.In order to mitigate this impa

Where is mining on the Water Stewardship Journey?

Where is Mining on the Water Stewardship Journey?

Three years ago, 27 of the world’s largest mining and metals companies pledged action to support the responsible use of water through the launch of the International Council on Mining and Metals’ (ICMM’s) position statement on water stewardship. By signing up to the position statement, members committed to transparent, consistent disclosure on water performance, managing water at operations effectively and collaborating with others to achieve resp
