Longwall top coal caving (LTCC) is a relatively new method of mining thick coal seams that is currently achieving high productivity and efficiency in application, particularly in China. The technique is similar to traditional longwall mining in that a cutting head slices coal from the lower section of the coal seam onto a conveyor belt [.]
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically – m (2 ft 0 in–3 ft 3 in) thick). The longwall panel (the block of coal that is being mined) is typically 3–4 km (– mi) long and 250–400 m (820–1,310 ft) wide.

May 21, 2018· Abstract: The theoretical equation of initial topcoal boundary (ITCB) is one of the fundamental problems of topcoal drawing law in longwall topcoal caving (LTCC) mining. The granular mechanical model of ITCB is established based on loose medium flow field theory.
Mining operations in section "b" are similar to conventional longwall top coal caving (CLTCC) while the working of section "c" is similar to multislice longwall mining technology. The shield support has a wire mesh laying device on the top to form an artificial roof for the next section "a" of the next new panel.
longwall mining Longwall mining is an underground method of excavating coal from tabular deposits, as well as soft mineral deposits such as potash. Large rectangular blocks of coal are defined during the development stage of the mine and are then extracted in a single continuous operation.
