Review of the Effect of Blast initiation Delay Timing on Blasting fragmentation By Taiwo Blessing Olamide  GIANT MINER INTRODUCTION  Do you know that; Explosive energy is higher when the shock energy supply for the initiation is high and accurate. Also that, most mining operations uses inaccurate blast time and initiation timing. Two things affect Blasting efficiency appart from the blast parameters and rock properties.  These are; 1. the initiation system and 2. the initiation approach.  This article give a brief review on Professor Takis Katsabanis and Nikolaos Gkikizas-Lamptopoupos work. Professor Takis is an explosive Engineer, lecturer in Queen's university Ontario, Canada. Prof Takis of Queen's university Canada with one of His master's student Nicholaos Gkikizas worked on a project relating to this in 2016. The Thesis focus on examination of the effect of Time delay on fragmentation.  The project was effectively experiments in the university R...

1. INTRODUCTION Blasting operation is one of the mine operation begin communition process. It is define as the process of using energy generated through explosive detonation for rock mass fragmentation. In a simple definition, I explain mining engineering to be a profession that provide needed mineral resources through application of safe technology. Mining related with the earth crust in a safe approach to release the naturally deposited mineral resources for human use. Mining Field surely make sense and can't be look down on because of the need for Innovation and technological development in manufacturing companies. The world currently have enough space ships, aircraft, cars, motorcycles and many heavy equipment that demands high supply of metals and fuel minerals. Currently, we consumed more salt, uses more cement produce from limestone, clay, iron ore, gypsum, human being keep constructing more roads with asphalt produced from the mixture of bitumen and granite dust. Infact, mo...

Brief on Blasting Design Blasting operation is one of the most important operation, looking from the capital influence on operation cost, the important of Blasting result on downstream operations and the place of safety. Most mine and quarries are not sensitive enough to understand the principle of Blasting operation and it significant in mine profit margin, because all Blasting is Blasting to them provided the ore ore industrial rock mass is broken down. Some of the blast design by operators in common quarries around Africa and others continent where small scale miners and Artisanal miners dominate are extremely poor and give low Explosive Energy ultilization. It has been proved by many research that poor blast Design with lack of agreement between the blast parameters like burden, spacing, stemming length, subdrill among others will definitely produce poor fragmentation with high environmental illness such as ground vibration, airblast, noise, flyrock among others. Giant Africa mines...

Blow out and flyrock is one of the evidence of poor and unprofessional blasting operation. This can result from poor steaming and overloading of holes and sometimes result from low charge weight. Energy is define as the ability to get the job done, the capacity to overcome the energy barrier. There are many ways to generate energy but for rock breaking, the use of explosive had been the most adopted means since 1900s. In every proper work done, professionalism is very important. Lack of professionalism result into disaster and accident. Since the aim of mining is to promote safety first through new innovation, inventories and safety management system, then the call for help to ensure this is achieve in Artisanal and small scale mines is important. Fact The artisanal miners will keep existing in the stope of mining operation as they has always be because if the following reasons: 1. challenge of start up capital in developing countries to set up large scale mine 2. large sca...

Brief Summary We must be alive to get all the money we are dreaming and thinking about! Mining still remains the most lucrative business in the world with high impact on Technology Development. But the level of safety at the blasting operation cycle is minimal due to lack of sensitivity despite millions of Research work on this area. This article was put together By Taiwo Blessing Olamide to sensitize the World mining sectors on the need to get involved in small scale mining to avoid unforeseen disaster. What blasting may look like if picture from a perspective Check below picture to have a view of what blasting is and what quantum physic can be involved in getting the rock fragmented instantanous casting of fragments from overloaded blasting Article Looking are many developed countries it becomes clearer that they are all functioning well in their large scale mines. Likewise the developing countries, they tends to have some level of success in the record of medium scale mi...

        Sir Dyno Nobel Why Blasting? The rock Mass contain the ore mineral which is the mining engineer major target. Mineral resources are inevitable material needed for Technological innovation and national development. The place of this mineral resources can not be suschanged neither can it be replaced with synthetic materials. By definition, I describe mineral as solid inorganic naturally occurring matter, that is been generated during magma eruption through sufficient time cooling and interrelate and exchange of element in the liquified rock lava. The mining engineer as well known by other disciplines involve themselves in getting the ore from the Earth crust and refining it to fit end user's need. The extraction process begin from altering the Earth land form through wide range of excavation and degredation attempt to get the so called overburden material removed in order to gain access to the enriched ore vein. Emphasis on Bowen series reaction*: D...

#campaign_against_unsafeBlast Brief Introduction It's clear that unsafe blasting is the father of unwanted occurrences. This make all move in the wrong time give birth to the wrong event. All mining operations must be planned properly before in site action. A look at explosive energy  Explosive energy distribution is almost a stochastic  discrete event, the explosion and detonation energy can sometimes be unfamiliar if there is change in rock property stimulation and expectation. Let all blasting put needed factor of safety in place to account for unexpected entities. Rock Mass as a discountinous, heterogeneous, anisotropic and non elastic material host the ore, the unmine rock form the supporting body; damaging the supporting rock is a call to hazardous events. The energy generator is the explosive, but the explosive will always remain calm until the stimulating wave is in touch with it. As mining engineer in this new year, let all our relationship with explosive ...
