The German Lignite Industry in 2020

Germany’s domestic lignite output decreased by 23.9 Mt, which equals 18.2 %, from 131.3 Mt to 107.4 Mt between 2019 and 2020. The lignite extracted in 2020 had a net calorific value of 33.4 Mtce. 93.1 Mt, or almost 87 %, of that output were used in utility power plants supplying the general public. This translates into a decrease of 19.1 % compared to ...

Applications of Industrial Computed Tomography in the Mining Sector

Industrial computed tomography (CT) is a non-destructive X-ray computerized method for studying the three-dimensional (3D) distribution and microtexture of phases within individual solid samples. For geological and mineral product samples, CT allows visualization of phases with significant density contrast as well as the recognition of gas and fluid inclusions. Also, the technique precisely defines the in-situ location of minerals of ...

Numerical Simulation of Shaft Sinking Using the Artificial Freezing Method

A potash mine in Kaliningrad, Russia is to be developed. Two shafts are planned to be sunk to extract the potash deposits in approximately 1,100 m depth and for general mine operation. Demanding lithological layers, namely alternating clays and floating sands combined with high pressure aquifers in large depths pose challenging circumstances for the sinking of the shafts. To overcome ...
