The application of LTCC in panels A1, Figure 3 Longwall top coal caving system GEOTECHNICAL CONSIDERATIONS FOR LONGWALL TOP COAL CAVING lower end of the scale for most coal mines in Austra lia. The smaller roadway dimensions are
A brief description of longwall top coal caving (LTCC) is included at the end of the Longwall section of the Fundamentals of Coal Mining module of this web site. Despite the fact that there are numerous coal seams in Australia which are thick enough for LTCC to be used to increase recoveries, potentially at a reduced cost/tonne, there has been little application of the process to date.

This app has been developed for the students of Minerals and Energy Resources Engineering (MERE) subjects at the University of New South Wales (UNSW), Australia. It is intended to provide an introduction into the longwall top coal caving (LTCC) mining method through an
The aim of this project was to provide the Australian underground coal mining industry with an up to date, state of the art summary of the Longwall Top Coal Caving (LTCC) mining system and its potential for application in Australia.
In many cases the top coal caving is the primary production mechanism from the face rather than coal cutting, and overall face cycle times depend entirely on caving rates rather than shearing rates. Research conducted previously on coal resources has identified that over billion tonnes of measured resources of coal in Australia lies in thick seams, seams of m or greater.
