ROCK AND MINING REVIEW

 The Earth consist of various sphere including be the hydrosphere (water), lithosphere (land), the atmosphere (space region), the hemisphere and many other sphere. The most valuable among them all that supports the manufacturing and innovation is the lithosphere. The land host in place millions of Mineral components. Mineral as we know it to be is a solid inorganic  substance, generally formed by inorganic process with crystalize structure and consistent of definite chemical composition.  Almost everything around us now consist of one or more mineral. How is minerals formed? The journey of minerals begin from rock formation, to understand the origination of mineral we have to know a bit more about rock and their formation process. Because, rock is an accommodation of various mineral, and the breaking down of this rock through weathering process results in the detachment of minerals into separate grains. Teaching the formation of rock in this slide will assist us in learni...

Understanding Flyrock control: Initiation Technique control

Image
INTRODUCTION Blast-induced fly rock generation occurs when rock fragments are thrown beyond the blast area, posing safety risks [1-3]. Causes include inadequate blast design, excessive explosive charge, or poor stemming. Control measures involve proper blast design, use of suitable explosives, adequate stemming, and implementing safety zones to minimize fly rock hazards. Preventing flyrock in blasting involves careful parameter design and analysis, including WipFrag analysis. Here are key steps: 1. Blast Design : Ensure a well-designed blast pattern, considering rock properties and site conditions. Optimize burden (distance between blastholes) and spacing (distance between rows of blastholes) based on rock type and desired fragmentation. 2. Explosive Selection: Choose explosives that match the rock type and desired fragmentation. Avoid excessive explosive charges that could lead to uncontrollable energy release. 3. Blasthole Design : Use proper hole diameter and depth based on geologic...
