Mining geology is an applied science which combines the principles of economic geology and mining engineering to the development of a defined mineral resource. Mining geologists and engineers work to develop an identified ore deposit to economically extract the ore. Mining geology is the process of exploration and exploitation of ore or economic minerals …

Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.

Mine Geology. A Mine Geologist is defined as a geologist that is responsible for using ore body knowledge for short-term mine planning and deciding material movement for ore or waste. Mine geologists are typically located at an active mining operation. Their day-to-day job is to collect, analyze, interpret, and communicate geological and assay ...

Feb 26, 2018· Underground Mining Geology. In the previous topic we learned that the economics of mining is particularly related to the amount of ore that can be produced and the amount of waste rock that must be moved. That makes underground mining particularly suited to structurally compact ore bodies with high grade ores which don't require an …

Prospecting. and exploration. Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, orientation in ...

Jan 25, 2021· It is used to retrieve ore that contains one or more valuable materials that are deep below the ground. There are two main stages in this type of mining, which are development mining and production mining. Development mining is the initial phase of removing the non-valuable components such as rock to access the targeted minerals.

Jan 09, 2020· Coal Mining Geology Introduction. Many obstacles or discontinuities in coal seams, mine floors, and roofs have geologic origins. Changes in the vertical and lateral arrangement of different rock types and rock bedding are related to the manner in which the rock was deposited, and in some cases, deformed after burial.

Jun 25, 2013· Classification of Mineral Resources and Reserves. In the early days of mining there were no standards for the reporting of mineral assets. Companies, or individuals, would usually take grades observed in drill core and using some clever geometry extrapolate them to define a deposit. This usually involved a large amount of guesswork …
