We define mining as the process of extracting useful materials from the Earth. But what are these useful materials and how do we get them? The useful materials we are talking about are minerals. The Earth has more than 3 500 different kinds of minerals. Minerals we mine include gold, copper, iron, or uranium. We use these minerals everyday for many...
Explorationis the name of the process for looking for minerals. In this step, scientists use information from the Earth to look for evidence of the minerals they want. This step must happen before people can start mining. The minerals that people mine are often found with certain types of rock. We call rock containing minerals ore. When we find a l...
Mining companies can use geophysics to measure certain properties. Geophysics is the study of physical properties of the Earth. This includes studying the Earth's gravitational, magnetic and electrical fields. Geophysicistsconduct surveys of these fields so they can create images. They usually measure these fields at the Earth's surface with specia...
Other surveys and methods are also done using geology. Geology is the study of the Earth, its history, materials, and processes. Geologists are the scientists who study those aspects of the Earth. A geological surveyis a detailed investigation of the geology below a specific piece of ground. The investigation of an area may begin with mapping the v...
Geologists use the information collected from the surveys and samples to make geological maps. These maps help mining companies find the best places for mines. Geologists will also analyse the data to determine which areas had the most minerals of interest. Information from the lab will tell them about the percentage of the mineral within the ore. ...

Oct 13, 2022 · The mine’s depth will influence the lumber support design – the deeper the mine, the more lumber is needed. You can use lumber in the mines for support raises, drifts, shafts, stapes, and more. A standard design setup would be two long, thick pieces of lumber called “posts” with a shorter piece on top of the two posts called a “cap” with “lugging” connecting the pieces.

Oct 19, 2023 · Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore. Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times. Prehistoric people first mined flint, which was ideal for tools and weapons since ...
