Caterpillar to exit underground longwall mining business with
IM can now exclusively reveal that Caterpillar Inc is set to effectively withdraw completely from underground coal and soft rock mining through the divestment of its longwall business to Germany’s Hauhinco Maschinenfabrik GmbH & Co KG, based in Sprockhövel, North Rhine-Westphalia.In simple words, longwall mining is a method of underground mining, in which coal is extracted from 60m to 200m long faces, moving continuously in one direction over large distances, leaving behind the goaf. The goaf is packed or allowed to cave. Longwall Mining is currently the main method of underground coal mining in Australia.What is Longwall Mining Method and its types?

influence of advance speed on overburden movement
1. Introduction. With the development of coal mining technology, the improvement in longwall face machinery, equipment manufacturing level and the continuous improvement in management level, high-intensity mining with large longwall faces, rapid advances, large-scale production and high efficiency have become the main In Indonesia, the adoption of the underground coal mining method is discussed to extend coal production. However, the geological conditions in Indonesia are very weak. In particular, the mechanical properties of the immediate roof/floor in shallow depths are weaker than those of coal. Therefore, the control measures to maintain Numerical Simulation on Pillar Design for Longwall Mining under

Assessment of roof fall risk in longwall coal mines
The longwall mining system is the main system used in Poland’s hard coal mines. Retreat longwalls with natural roof caving in the gob are the most common. Difficult mining conditions (e.g. significant depth, influence of previous mining activities, rock mass tremors, geological conditions) result in minor and massive roof falls in the longwalls.Longwall mining is a primary method for extracting coal from underground mines. As shown in Figure 1, three kinds of mining equipment used in the longwall face are a shearer, an armored face conveyor (AFC), and a roof support system.The shearer moves back and forth along a rail connected to the AFC, while the Applied Sciences Free Full-Text Longwall Mining
