Dhruv Katoria et al 246 extraction of coal. Depending on the content of volatiles, coal is classified into Lignite, Subbituminous coal, Bituminous coal and Anthracite. Open cast mining and underground mining (room pillar, long wall, drift, shaft, slope mining) are some types of coal mining.

The impact energy produced by blast casting is able to break and cast rocks, yet the strong vibration effects caused at the same time would threaten the safety of mines. Based on the theory of Janbu's Limit Equilibrium Method (LEM), pseudostatic method has been incorporated to analyze the influence of dynamic loads of blasting on slope stability.

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

Mechanical drilling and blasting are the first steps in extracting ore from most developed openpit mines and are the most common method used to remove hard rock overburden. While there are many mechanical devices capable of loosening hard rock, explosives are the preferred method as no mechanical device can currently match the fracturing capability of energy contained in explosive .

Jun 14, 2018· ANFO has found wide use in coal mining, quarrying, metal mining, and civil construction in undemanding applications where the advantages of ANFO's low cost and ease of use matter more than the benefits offered by conventional industrial explosives, such as water resistance, high detonation velocity, and performance in small diameters.

A mold is formed into the geometric shape of a desired part. Molten metal is then poured into the mold, the mold holds this material in shape as it solidifies. A metal casting is created. Although this seems rather simple, the manufacturing process of metal casting is both a science and an art. Let's begin our study of metal casting with the mold.

will include noise from drilling, blasting, operation of mining equipment, crushing and screening, conveyor operation, processing plant, stockpiling and loading of ore, mine waste disposal operations, power generation and vehicle movements. With regard to blasting, explosives are used to dislodge overburden
