 The abstract summarises the research conducted on a new method of non-pillar coal mining in long wall top coal caving, LTCC, panels. The method uses four techniques to control the surrounding rock of the retained entry, including the use of constant resistance and large deformation anchor cables, directional roof split blasting, blocking gang support system, BGSS, and temporary support systems. The results show that the surrounding rock of the retained entry is stabilized at 200 meters behind the working face, and the deformation of the retained entry is within a reasonable range at 180 to 190 meters behind the mining panel.
