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...
