Geology: Characteristics and classification of mineral deposits; application of geology to mining; geological structures; folds, faults, fractures, fissures etc. methods of exploration and delineation of the ore bodies; boring through disturbed strata; bore hole survey; sampling; estimation of cut-off grade and ore reserve; losses of mineral in mining.

Steps in Opencast mining 1) Determination of mine boundaries: Exclusion of: high SR area (deep seated, hill, thinning/splitting of seam, stone parting, geologically disturbed areas (faults), low quality areas, etc. natural boundaries (river/nallah, faults), township, railway line, operational factors like optimum strike length for transportation.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal. This paper focuses on open-pit surface mining,

ADVERTISEMENTS: In this article we will discuss about the types of drilling methods used in mining. The types are: 1. Percussive Drilling 2. Rotary Drilling. Method # 1. Percussive Drilling: In this method which is the oldest one of drilling, the hole is drilled by striking .

Chapter 8 is a practical chapter. A copper mining group, Antofagasta, is valued with different valuation methods. 1.3 Definition of terms. Valuation approaches for metals and for mining companies are similar; therefore, for convenience the term "mining companies" will be used for "metals and mining .

3 Surface mining: Is a type of mining in which soil and rock overlying the mineral deposit (the overburden) are removed. Surface mining is the predominant exploitation method worldwide. Surface mining requires large capital investment (primarily expensive transportation equipment), but generally results in: - High productivity (i.e., high output rate of ore)

techniques, extends to other facets of opencast mining. Draglines, generally used in surface coal mines, prove to be a successful mining method with distinct capital and operating cost benefits. ... Mining methods have, until the past decade, been restricted

Mining waste is the high-volume material that originates from the processes of excavation, dressing and further physical and chemical processing of wide range of metalliferous and non-metalliferous minerals by opencast and deep shaft methods.

This SME classic is both a reference book for the working engineer and a textbook for the mining student. This hardcover edition gives a brief history of surface mining and a general overview of the state of surface mining today--topics range from production and productivity to technological developments and trends in equipment. This extremely useful text takes the approach that exploration ...

opencast coal mining methods. Underground mining is practical when The ore body is too deep to mine profitably by open pit The grades or quality of the orebody are high enough to cover costs Underground mining has a lower ground footprint than open pit mining The underground mining methods we use include room and pillar narrow vein stoping and largescale mechanised mining

Currently all major opencast mining is undertaken using the strip mining method with draglines. All hard overburden (shale/sandstone) and coal is blasted using bulk explosives (heavy ANFO emulsion). The coal is transported by truck to the Crushing and Pillar Screening Plant. Smaller opencast .
