The charge length in blasting operations significantly influences the fragmentation of rock (Taiwo, 2022)i. It defines the quantity of explosive loaded into each blast hole, directly correlating with the amount of energy generated along each meter of the borehole profile. An optimal charge length ensures efficient energy distribution, which is critical for achieving the desired fragmentation size and shape.
Charge length is contingent upon several factors, including the total length of the boreho

Blast fragmentation analysis is a crucial process in mining, designed to evaluate the size distribution of rock fragments after a blast. It plays a key role in optimizing the performance of downstream operations, such as loading, hauling, crushing, and grinding. By assessing the fragmentation, mining engineers can determine how well the blast was executed and make adjustments to improve future blasts.
Effective fragmentation ensures that the rock size is compatible with the crusher gape, minimizi
Definition of Burden
Burden is defined as the horizontal distance from the front of the blast hole to the nearest free face of rock. It plays a crucial role in determining how effectively explosive energy is utilized during blasting operations.
Burden and Spacing
Burden is closely related to spacing, which is the distance between adjacent blast holes. Together, these factors influence the distribution of explosive energy throughout the rock mass. Optimal burden and spacing ensure that energy is eff
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
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
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
