3D experimental investigation of multi-port caving technology in LTCC with extra-thick seams

This paper investigated the multi-port caving technology to improve the top coal recovery and caving efficiency of the longwall top coal caving(LTCC)in extra-thick seams.The 3D drawing experiments are designed based on the actual geological conditions of Panel 8222 in the Tashan Coal Mine.Results in...
