International Journal of Rock Mechanics and Minings Sciences, 2016
Abstract Longwall mining is the most profitable and safe coal extraction method from deep seated deposits. Understanding the interaction between powered supports, surrounding rock and coal strata is the key for successful operation. In this respect, numerical modelling techniques provide great insight into the behaviour of shield support especially ...

Longwall Production with Subsidence

2016
Subsidence is a ground settlement that occurs on the surface after the underground mine excavation. The amount of the subsidence is particularly high for caving method applied in the thick coal seams. Subsidence amount depends on the thickness of bed, the slope of bed, and geological formations.
