EXPLOSIVE AND BLASTING DESIGN AND SAFETY MEASURE: TECHNOLOGY FOR SAFE ROCK BLAST AND EFFICIENT USE OF EXPLOSIVE

Image
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 optimization: Micro fracture increase to supplement rock breakage

Image
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...

MINING JOB SEARCHING KEY: THE SECRET JOB DOOR

Image
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...

Gem Stone Mining Tips

Image
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...

Sustainable Frame Work for Financing Mining Sector of Edo State

Image
The availability of immense solid Mineral  in Edo is no longer in doubt as we have proven reserve of Dolomite, limestone, feldspar, kaolin, Granite , Gold , Sand among others. This becomes more authenticated when Journal of National research Volume 3, No.11 published in 2013 shows the distribution of limestone, dolomite and Marble within Akoko Edo, okpella, igara, atte, Etsako to mention few geographical locations. This was the view point discribled by Gov. Godwin Obaseki in December 18, 2016 on Nigeria Observer news that "Edo solid minerals can generate more revenue than oil".  But to strengthen the investor in the mining industry require a clear Road Maps for a sustainable funding.  Who are the Miners? A Miner is someone or a company having relevant Mining Rights, permits or licences from the Federal Government that are currently working no matter how small the level of operations is. Hence this Narrow our search to active Title Holders and not Lease Specula...

This article will dendriticaly explain how someone can add value to himself,  how to become the best in your field of study and get the job of your dream. It not new that securing job nowadays is very difficult for fresh graduates and that only those flexible enough with content rich brain can secure for themselves good job even after 4/5 years of study. Is not by grade or certificate now, the new currency exchange in labor market for job is value the son of knowledge. Thanks to God almighty, the giver of all wisdom, wisdom is the principal thing, in all your gettings get wisdom and knowledge. Actually, most Mining Engineers are paid base on productiveness, efficiency and knowledge inbuilt. This fact can't be compromised, how good is it if you can be sincere with yourself as a student reading this article or as a graduate reading this article, ARE YOU EMPLOYABLE? CAN YOU ACTUALLY DELIVER BY DEFENDING THE CERTIFICATE YOU CARRY??  Job interview is a package put ...

The mystery of Mining engineer Tools: Drilling and Blasting

Image
 I will be sharing knowledge on most important aspect of Mining Engineering, which is Drilling and blasting.  Actually, I always considered this as the most important aspect because as a Mining Engineer this is our tool, this is the only aspect that other Engineers can never share with us as a Miner. This aspect is wide and extend to various other Fields. Some of which are: 1.Petroleum in terms of casing perforation, Exploration (seismic survey) among other applications 2. Civil engineering works in the aspect of road construction ( road obstacle rock fragmentation), subsurface liquidification/compaction to mention few. 3. Borehole drilling: most time during Borehole drilling bed rock encountered are fragmented by blasting. This is just few out of the application of drilling and blasting in other Fields. What is Drilling? Drilling is the creation of artificial hole into rock by man controlled or automated machines without the admittance of man in the hole. M...
