Description	This is the most common method for underground coal mining where engineering has advanced technological capabilities. The extension of the application of longwall mining to pitching and steep pitching coal seams with moderate thicknesses opens up a new era of mining. It would be fair statement to say that to completely cover the topic of longwall mining a separate volume would be required. This section has been limited to the principles of longwall mining and strata mechanics under the four following chapter headings: Principal mining systems with equal consideration to advancing and retreat sequences, layouts and productivity. Stability of panel stope structure with a summarizing concept of longwall support load, types of powered face support and an approximation of hydraulic support as a rheological system. Strata mechanics in relation to stress redistribution in longwall mining and the resulting stress patterns in the abutments, face-ends and gobs. The effect of stowing on stress redistributions and the interaction of stresses between longwall faces. Caving mechanics in longwall mining and physical modeling of strata caving, mining subsidence and controlled caving and subsidence. Book Name: Strata Mechanics in Coal Mining
