Well Shaft Drilling
Well shaft drilling is an innovative technique used to drill into the earth. This method is mainly used when creating large, deep holes or tunnels. It is commonly used in the construction industry as well as in exploration projects, such as oil and gas drilling.
The primary b......
leaching mining
Heap leaching is an industrial mining process used to extract precious metals such as gold and silver from ore. In this process, ore is crushed and placed on a leaching pad. A cyanide solution is then introduced to the pad in order to extract the metals into solution form, which can then be recove......
Natural Gamma Spectral Logging
Logging in natural γ-ray spectroscopy
Logging in natural γ-ray spectroscopy (NGS) is a technique used in the oil and gas industry to assess the content of specific materials in a specified area. This is achieved by measuring the energy of emitted γ-ray photons from natural sources, such as ura......
Saturation Logging
What is Saturation Logging
Saturation logging, also known as resistivity and saturation log, is a type of geophysical logging method used to measure the amount of hydrocarbons present in a potential oil reservoir. The two main measurements taken using the method are the electrical resistivity and......
Physical and mechanical properties of rock mass
Introduction
Rocks as a natural material consist of numerous different minerals and they form the basis of the earth’s crust. In addition, their composition and texture determine their physical, mechanical and chemical characters. Therefore, rock mechanics deals with the interactions between roc......
