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. Energy is defined by various scholars as the ability needs to do work. The work before Explosive during detonation is to explode rock mass, fragment rock mass, throw rock piles and to  cause other negative effects like ground vibration, airblast, and rock projection (flyrock) Sequence of Explosive energy ULTILIZATION during Blasting  The light energy travels faster than all others energy, it shows the initiation direction of Explosive charge detonation.  Check t...

Pre Blasting and post Blasting inspection for data collection and blast design is very important so as to performance a profitable and productive Blasting. Some of the pre-blasting inspection carried out before Blasting includes; 1. Ground water condition (in-hole water check) 2. Rock face discontinuity mapping 3. Drilling parameters collection. 4. Free face checking. 1. Ground water condition (in hole water) Water may be present in the mine either through surface inflow or underground water outflow. Ground water condition affects Blasting materials, expecially when using a non water resistant Explosive like ANFO. This may result into MISFIRE and poor fragmentation. All holes must be inspected and those with water should be noted. Water tend to reduce the sensitivity of non water resistant Explosive. Explosive like Dynogel and emulsion gel and other water resistant Explosive should be use in noted water filled holes. Hole with water can also be drained or flush by high pres...

The main aim of mining is to secure profit. This in most cases may be affected by mine operation cost if not properly managed. Drilling and Blasting plays high role in ensuring profit in Mineral exploitation. If the expenses incur on drilling and Blasting yield poor result, it tends to affect all the downstream operation cost. It therefore good that blast design be done and monitored thoroughly by the Mine supervisor. This is liken to safety in the mine, workers life is very important and must be given principal consideration. Blasting must be done safely with no accident record or any form of misfire. Explosive is dangerous when poorly handle but peaceful if well handled. In 1960s before Alfred Nobel light up Explosive works, the use of Nitroglycerin Explosive base, TNT and puliminating Mercury & gold had cause great havoc due to there high sensitivity. But for the discovery of Ammonium Nitrate base Explosive which are less sensitive but high exotically sensitive. Explosive is now...

Blasting Design, safety and Explosive handling and Storage: Many scholar contribution worldwide [07/06, 8:33 p.m.] Hanif Ullah khan: The purpose of a good open pit blast design (production blast) is to achieve the following at acceptable costs...: -fragmentation, muckpile profile for safe and efficient loading and hauling and other downstream processee -wall stability -minimum environmental impacts (undesirable effects of a blast): ground vibrations, noise, airblast, _flyrock_, dust and fumes. [07/06, 8:33 p.m.] Hanif Ullah khan: I will be throwing in some of the rules of thumb for open pit blast design. A rule of thumb is basically a principle with broad application that is not intended to be strictly accurate but can be quite handy in coming up with sound and economic designs [07/06, 8:33 p.m.] Hanif Ullah khan: -Mining equipment: equipment also has a say in the blast deasign process. Drilling equipment dictates blasthole diameter and depth limits. Loading ...

Blasting is the technology use in breaking rock mass or boulders into specified require sizes by the use of Explosive. The main objective of Blasting is to reduce rock/Mineral size so as to minimize cost of comminution and other downstream processes. Poor fragmentation affect other Mining operations like; loading, Haulage, crushing, and separation process. It also increase production cost and operation cost. Most Quarry and mine practice secondary Blasting or implement hydraulic breaker to further reduce Blasting output. It therefore good to subscribe to better blast design to ensure good blast output result so as to avoid further reduction expenses. What is micro fracture? Fractures are crack or breakage in rock mass. Micro fractures are the cracks create in rock mass by Explosion shock waves during Explosive charge detonation. What is the important of micro fracture in rock fragmentation? The micro fracture creates slabbing in rock mass and t...

It never ends until you give up!! As an experience mining Engineer or graduate you have hundred plus job opportunities available online for you. All you need is to get the formula right. The general formula for you getting job is titled: "Add up and Network it" You first add up value and do the networking. Recently I was baffled about the available opportunities in Mining after checking through people's request for job on Facebook pages and groups. I decided to take this up and Network friends, make online research to get the crystal view of mining in the world. I sign up for more than four (4) website and keep searching for mining job basin, firstly worldwide and later National. I was supprise to access and get notification from more than three websites on available Mining job from companies. Many companies release their vacancy advert internally, it requires smart job seekers to gain access to this. I will be sharing with us five Giant job searching app and website that...

Cost and Technical Requirements for starting/operating a small scale gemstone Mine Nigeria is a blessed a country with a lot of minerals most especially solid minerals like Gemstone e.g Gold, Diamond, Ruby, Tourmaline, Sapphire and more  To start with, Artisanal and Small-Scale Mining (ASM) are formal or informal operations with predominantly simplified forms of exploration, extraction, processing and transportation. ... While ASM can provide a mean to generate income to get out of poverty, it can also be a way to trap miners and the families in poverty. Briefly, on the mineral we are about to get is technical requirement and cost for mining the mineral. Gemstone is a piece of mineral with special properties like colour, hardness among others which makes it different from other earth forming Mineral. This mineral is such that after it has been cut and polished is made into a piece of jewelry or another accessory FORMATION OF GEMSTONES Gemstones are of substantial monet...
