Undergraduates time is a time to discover who you are! A time to change you level and know the level you belong. Not all about the lecture you are able to receive now, but about what you are able to retain. You need to know this early, so it will not be late. There is a grace that help a man to study, to know, to excel and to win on campus. The issue and challenge is not the lecturer, is not about your head but the limitation is knowledge. Knowledge about what is available is important, what you have will always remain in you until you unveil it. The grace of the Lord that brings salvation had appear unto all men.. Titus 3:11 You have heard about the great things the Lord did and is doing in my life even when I was still in FUTA as an undergraduate, how I receive grace to defeat many courses and have A's, how I overcome the war of many exam and outrun marking guide by the help of the holy spirit. I don't want you to be ignorant of what God is able to do if you trust HIM and liv...

MAKING THE MINE A SAFE PLACE: DESIGN OR RE-SIGN   a typical underground working level in a competent formation Many will agree with me that, mining is far different from all other profession, the fact that you have potential and title will not be a respectable fact for falling block or wedge not to break the head of mine manager who fails to put a safe design and measure in place for safe Mining. Also, I submit to you that rock formation has a major challenge of heterogeneity, non elastic, Discontinum, and Anisotropic characteristics which make it detrimental to stress field alterations under excavation and Blasting operation. Since Mining involved holing and extracting, by creating artificial cavity into the insitu rock, ground as the case may apply to remove what is supporting the lithosphere all in the name of profit and economic development. The standard is inevitable, you disturb the crust, the crust adjust and react to achieve stability. In view of this, making su...

INTRODUCTION TO SHAFT AND SHAFT USE IN MINING BY GIANT MINER  Shaft as related to underground mine is a vertical or an inclined opening extend from the surface into the ground to provide access to underground working area.  it not a news that we can mine the ore by surface and underground mining method. Now underground methods requires that the mining Engineers move into the subsurface with their equipments to extract the ore. We can't just disappear at the surface and appear in the underground like a magician!  We provide an access into the ore without stripping the overburden materials.  These access are reference to two, the primary development and secondary development. Shaft is a primary development opening as it has a life span greater than that of the mine. It provide access for personnel entrance into the underground mine, provide duct for ventilation, and many more. Shaft can be classified into categories base on the following: 1 Base in uses 2. ...

Blasting and Mining cost Blasting operation is one of the Technology use in breaking rock mass into smaller sizes. Since rock exist as an Anisotropic and heterogenous massive solid at the lithosphere it therefore requires the use of energetic Technique like blasting to generate sufficient shock wave for fracturing and gas Energy for casting down. Mining operation is known to be a capital intensive project whether small scale or large scale, likewise the place of safety is insuschangable. At this expenses, Blasting operation dictates the cost of other preceding operation and even the downstream operations. Blasting operation is a professional work that and a bit difficult to design for ordinary person since two major factors affect the output result which are the controllable factors such as burden and other hole geometry parameters and uncontrollable factors such as rock strength and other geological and geotechnical properties of rock. Making balance between this two facto...

Short ways reduce open pit mine operation cost: 1. Proper design: remember proper preparation prevent poor performance (5p's  key of good operation system). When it comes to open pit mining I always like to make mine plan and Design first as the key ways to optimize and garantee profitability. See through this: The following factors are the dictator of stripping ratio (Stripping cost), Drilling and Blasting, loading and haulage operation, then processing operation. Find the factors below and how that affects the about operation: Factor number 1: Bench height: This is the maximum vertical extension of the mine bench also define as the vertical distance from the toe to crest of a bench. This factor determine the type of loading equipment that will be strictly permit in the mine for loading because, the loading boom of the equipment must not be longer than the bench height. Small loading equipment means low production or high cost of getting enough loading equipment that will fit for ...

LEARN ON BLASTING PRINCIPLE AND MECHANICS BEHIND CONTROL BLASTING INTRODUCTION From the view of Hoek brown failure graph and failure criterion equation adjustments using the Geological structural index GSI, variation is confirmed to occur in the rock strength parameters due to the effect of Blasting, this was shown in the addition of Rock disturbance factor D  to the determination of s,mb and a which are the rock factors constant. Rock is known to be DIANE (Disvontinous, Anisotropic, Heterogenous and non elastic) according to various claim by rock mechanist like N. Barton among others. Since rock has such dynamic characteristics, it becomes very difficult to understand the perfect behavior of Explosive energy and the quantity of powder require to cause the breaking and the casting of the rock mass.  Actually what the  generated during blast need to reflect is change in medium (solid to air, solid to liquid), this is the important of free face. Free face is the...

INTRODUCTION Operations in mining industry is mainly effected by the mine work because more cost is involved and safety is required.  Blasthole Drilling shows the creation of holes into the rock mass for the placement of Explosive with the intention of fragmentation. According to Barry, (2016) liberation process begin from the mine. Though libration occur in two ways, the intra granular and inter granular libration, both occur during Blasting and during comminution. All Mining Engineering is concern about is extracting the ore from the earth crust safely and getting it to the beneficiary plant for processing, in a bit to achieve this we have the earth stress field been Disturbed and the safety of men been questioned as the various activities in Mining affect both the biosphere and the Abiosohere. This article discuss the process of Blasting as a key way to getting the rock insitu fragmented and the place of safety Paramount as far as profit is concerned. The article als...
